LASER CUTTER SAFETY WARNINGS

Never expose yourselfto the laser beam since

it may cause physical burns and cancause severe eye damage. Proper useand care of this laser cutter system areessential to safe operation.Never operate the laser cutter systemwithout constant supervision of thecutting and engraving process. Exposureto the laser beam may cause ignition ofcombustible materials and start a fire. Never use PVC or other nonconductiveduct materials for the exhaust system.Static charges may build up and maycause a risk of fire or explosion.Always use fire rated rigid or flexiblemetal or metalized ducting in theexhaust system. Non-fire rated exhaustducting may increase the risk of fire.Always inspect the exhaust fan and ductwork for obstructions and ensureproper air flow exists before each use.Unobstructed and properly maintainedexhaust fan and duct work will reducethe risk of fire and effectively extractcaustic fumes and smoke.Never engrave or cut any unknownmaterial. Only engrave materials

recommended by the manufacturer. Thevaporization/melting of many materials,including but not limited to PVC andpolycarbonates, can give off hazardousfumes. Always refer to the Safety DataSheet (SDS) from the materialmanufacturer to determine the responseof any work material to extreme heat(burning/fire hazard) to prevent hazards.Always use the air assist asrecommended by the manufacturer,especially while cutting. Cuttingmovements are relatively slow andapply an extremely large amount of heatto the work piece. Avoid the build-up ofheat in order to reduce the risk of fire.Keep the interior of the laser cutter,including the table tray, clean and freeof debris. Clean the laser. A build-up ofcutting and engraving residue and debrisis dangerous and may increase the risk offire. Never look into the beam of thealignment laser. Eye injury can result.Never operate the alignment laserwithout the focus lens or other opticalelements of laser cutter in place. Theunfocused beam may be reflected out of

GENERAL SAFETY WARNINGSclothes, jewellery or long hair can be caughtin moving parts.Be careful removing work pieces from thelaser cutter. Cutting with a laser increasesthe temperature of the work piece and thetemperature of the work piece may remainhigh after laser cutter stops operating.Touching hot work pieces before they cooldown may result in burns.Do not let familiarity gained from frequentuse of laser cutters allow you to becomecomplacent and ignore laser cutter safetyprinciples. A careless action can causesevere injury within a fraction of a second.

Laser Cutter Use and CarePrevent idle laser cutter from being usedby children and do not allow personsunfamiliar with the laser cutter or theseinstructions to operate the laser cutter.Laser cutters can be dangerous in the handsof untrained users.

Maintain laser cutters. Check formisalignment or binding of moving parts,breakage of parts and any other conditionthat may affect the laser cutter’soperation. If damaged, have the lasercutter repaired before use. A poorlymaintained laser engraver may result in arisk of shock, fire and/or serious injury.Use the laser engraver in accordance withthese instructions, taking into account theworking conditions and the work to beperformed. Use of the laser engraver foroperations different from those intendedcould result in a hazardous situation.

Exhaust Management


25

SETUP

Choosing the Exhaust ManagementMethodThere are five options for managing theexhaust generated during the laserfabrication process:A. Onboard FanB. External Booster Fan (design flow

rate at least 90 CFM)C. Light Duty Filtration UnitD. Heavy Duty Filtration UnitE. Commercial/Industrial Mechanical

Exhaust System (design flow rate atleast 90 CFM)

When selecting an appropriate exhaustmanagement method, multiple factorsmust be considered, such as the intendedoperating location of the Dremel LC40Laser Cutter, the size of room where it willbe operated, and the frequency and

duration of laser fabrication. Consult Table3 below to determine an appropriateexhaust management method.Room size in Table 3 is based on ceilingheight of 8.5 feet. Adjust room size foractual ceiling height. If room size or laserfabrication time is not known, err on theside of caution and select the higherfabrication time and/or smaller room size.Home, office, and classroom scenarios inTable 3 are based on standard modelsfrom the EPA, ASHRAE, and CDPH, resultsmay vary based on your use location andoperating parameters. Always operate theDremel LC40 Laser Cutter in a well-ventilated area. Installer of Dremel LC40exhaust management system isresponsible for complying with applicablecodes and regulations including those forhazardous or noxious exhaust ventilationsystems.

This box can be movedanywhere on the screen simply by draggingit. The gear button in the top right cornerwill expand “advanced” settings for morecontrol. The “X” will minimize the box andcan be reopened by clicking on the pencilthat appears.

CUT This function is used when cutting througha work piece. This function is also called“vector” since a vector, or line file is neededin order to execute. The Laser Head willfollow the lines of the file. The LC40 ControlSoftware will detect up to 21 differentcolors in a line file and allow adjustment ofthe print settings based on those colors.The order that the different colors are cutcan be adjusted in the print preview screenonce ready to send.

Print Settings box (Cut)

HEAT – Adjust how quickly the laser isfiring, or how much heat is generated on thesurface of the work piece. Turning up theheat will cause charring for materials likewood or paper, but will create a glossy edgefor a material like acrylic.SPEED – Adjust how quickly the Laser Headmoves. Slowing the Laser Head down allowsit to cut deeper into the work piece, whileturning the speed up prevents the cut fromgoing as deep.DEPTH – adjust to control how deep thelaser will go into the work piece. Turning upthe depth will increase the likelihood thatthe work piece will be cut all the waythrough.# OF PASSES – adjust to control how manytimes the laser traces over the lines.Increasing the number of passes means thelaser will execute that job, then immediatelyexecute it in the exact same locationhowever many times entered. Increasing thenumber of passes can be an effective way toensure the work piece is cut completelythrough, especially as the thickness of thematerial increases.

SCOREThis function is used when it is preferrednot to cut all the way through the workpiece. This function requires a vector, orline type file and is most useful whenemphasizing the outline of text or an object.It is very similar to “cut,” but the softwarewill default to less powerful settings, in anattempt to mark the work piece, but not cutall the way through it.

BLACK/WHITE THRESHOLD – Use this toadjust the amount of black that is includedin the image. The furthest left setting willinclude a larger amount of black from thefile, while the furthest right setting willinclude less black, or a larger amount ofwhite.GRAYSCALE – Takes a black and whiteimage and assigns different densities ofdots to visually create a number of differentshades of gray. Darker areas of the imagewill have more dots, while lighter areas willhave less dots. This is useful for images thathave a lot of different colors, and it isdesired that the finished product appearmore realistic. This setting can be toggledon or off.INVERT – This setting will transform theimage so that the white areas becomeblack, and the black areas become white.DEPTH – Adjust to control how deep thelaser will go into the work piece. Increasingthe depth will remove more material, sothat a noticeable void is felt when touchingthe work piece, creating almost a 3D effect.

Reducing the depth will keep the surface ofthe work piece relatively flat or even.SPEED – Adjust how quickly the Laser Headmoves. Slowing the Laser Head down willgenerally make the engraving darker ordeeper, while increasing the speed typicallyresults in a lighter finish.RESOLUTION – 3 different resolutionoptions are available: low, medium, high.This setting adjusts the DPI (dots per inch)in the image, the low setting will be fasterand lighter than the high setting. In lowsetting the resolution is pixelated, orindividual dots are easy to see. The highsetting will result in a less pixelated finalresult.

JOB PREVIEWAfter pressing “start” the PREVIEW screenallows review of all the settings andplacement of the files before sending thejob to the laser. Changes can be made tothe order the files execute. By default,engraving is completed first then cutting. Ifother settings need to be adjusted, exit outof this box before sending the job. Ifeverything looks correct, the job can besent to the laser. The physical Start Buttonon the laser must be pressed twice beforethe job will begin.

TESTS & ALIGNMENTS

Mirror Alignment Overview



Fig. 28

Alignment of the mirrors is performedbefore the Dremel LC40 Laser Cutter isshipped. However, before the DremelLC40 Laser Cutter unit is used for thefirst time and periodically during its use,the mirror alignment should be checkedand adjusted if necessary.Misalignment most often occurs when:• Gantry is manually moved while the

motors are locked,• Air Assist Nozzle is displaced,• Laser Tube is replaced,• mirrors / lens are replaced, or• during shipping.

Alignment of the mirrors is necessary toensure that the Laser Beam remainsproperly aligned with the Focus Lens asthe Laser Head moves to all four cornersof the workspace. After alignment, theLaser Beam should be centered on theFocus Lens and perpendicular to it.Improperly aligned Laser Beam will resultin the focus point being out of line withthe centerline of the Laser Head (Fig. 28).

TESTS & ALIGNMENTS

4 Corner Mirror Alignment TestBefore running the first job, check tomake sure that the mirrors are properlyaligned. This test should also beperformed as a troubleshooting measurefor power loss, clipping (Laser Beamhitting Air Assist Nozzle), or incompletecutting. For this alignment test theDremel LC40 Laser Cutter must be “testfired” once in each corner of the machine.This is done to make sure the Laser Beamis following the correct path to themirrors, to the Laser Head, and ultimatelythrough the Focus Lens to the work piece.Note: Dremel LC40 Laser Cutter Lid mustbe closed for each test fire.Materials needed:

• Thermal paper (supplied). • 2.5mm hex wrench (supplied).

1. Open the Lid. 2. Place the thermal paper: Take a small

piece of thermal paper approximatelythe same size as the face of the lensand place it over the focus lens underMirror #3. Fig. 30.

3. Press the paper down with a finger sothat a circle appears thatdemonstrates the outer rim of thelens. Sometimes pencil lead or crayonwill help to show the edges of the lensand mirrors.

4. Position the Laser Head: Move theLaser Head into the upper left corner(Location A) of the workspace, Fig. 29.

5. Close the Lid.6. Using the LCD touch screen display,

test fire the Dremel LC40 Laser Cutter(by tapping Test Fire on the Homescreen) from the Test Fire screen. TheFire button will appear after all of thesystem checks are passed. Press thebutton one time and observe wherethe spot lands on the thermal paper. Ifthe spot does not appear, repeat. If itstill does not appear, change positionso it is possible to look through theopenings in the Tube Guard andconfirm that the Laser Tube is actuallyfiring.

7. Repeat Test Fire in other threecorners: Without removing the thermalpaper, repeat firing the Dremel LC40Laser Cutter once in each of the othercorners of the machine (Lower Left B,Lower Right C, Upper Right D). Fig. 29.a. Open the Lid.b. Position the Laser Head.c. Close the Lid.d. Repeat as in step 5. Observe which

mark is from which location. 8. Check Results: With the fourth corner

test fire complete, open the Lid andobserve the thermal tape. The fourspots should overlap each other (Fig.32). If the spots do not overlap asshown, perform the Mirror AlignmentProcedure on page 65.

9. Once the spots are aligned, placethermal paper under the Air AssistNozzle on the Honeycomb Plate at allfour corners. Fire the Dremel LC40Laser Cutter into each piece of

thermal paper using test fire and verifythat a circular spot appears on thepaper. This ensures that the Air AssistNozzle is not clipping the laser path. Ifthe spot is not circular, fine-tune theAir Assist Nozzle by loosening the setscrew and adjusting.

10. Once the mirror alignment test issuccessfully completed, the DremelLC40 Laser Cutter is ready for use.

TESTS & ALIGNMENTS

Mirror Alignment ProcedureSteps:

1. Gantry Alignment 2. Preparation 3. Verify centering and no clipping at

Mirror #1 4. Align Axis A-B (Y-Axis) using red dot

generated by the Alignment Laser(fig. 36).

5. Align Axis B-C (X-axis)6. Centering on focus lens. (Z-axis)

Materials needed:• Thermal paper (supplied). When supply

is exhausted, purchase adhesivebacked thermal paper.

• 2.5mm hex wrench (supplied).

Step 1: Gantry AlignmentThe first task of mirror alignment is toensure that the Gantry is perpendicularto the Y axis rails. Often misalignmentoccurs when the Gantry is bumped ormoved while the motors are in a lockedstate. 1. To verify alignment, push the Gantry all

the way forward until it contacts thefront stops and backward until itcontacts the rear stops.

2. The Gantry should touch the stops atthe same time on both the left andright side. If it touches evenly, move toStep 2: Preparation.

3. If the Gantry does not touch bothsides, the motor connector under thetube guard needs to be loosened. a. Do this by removing 3 screws of the

Tube Guard and lifting the TubeGuard up off of the posts. (see TubeGuard Removal, page 70)

b. Loosen the screw on the left side ofthe motor connector.

c. Shift the Gantry tight against thefront stops and hold evenly.

d. Tighten the screw on the motorconnector while holding the Gantry.

e. Replace the Tube Guard using greatcare not to damage any wires or theLaser Tube.

4. Rerun the four corners mirroralignment test to see if furtheralignment is necessary.

Step 2: Preparation Prepare your tools and workspace.1. Power On Dremel LC40 Laser Cutter:

The machine must be powered on tocontinue this procedure. Allow themachine time to boot up the touchscreen operating system.

2. Gather Tools: A 2.5 mm hex wrench(supplied) and thermal paper(supplied) are required to perform themirror alignment procedure.

NOTE: DO NOT over-tighten or over-loosen adjustment screws. Tightening orloosening any of the three adjustmentscrews on the mirrors or the red dotdiode will move the position in aparticular direction depending on thepositioning of the other screws. Someexperimenting is required to understandthe relationship of each screw and howadjusting one affects the alignmentlaser's red dot positioning. When adjusting the screws, use theabsolute minimum turn of the hex wrenchto move the red dot or the mirror intoposition. If one or two turns of the screwfrom the just seated screw position doesnot move the red dot into position, it isrecommended to release all three screwsback to the just seated position and startover. Over tightening the screws candamage the mirror holding plate. Checkfor any loose screws at either the mirrorholders, the lens, or anywhere on theGantry to ensure efficiency duringalignment procedure.

TESTS & ALIGNMENTS

Step 3: Verify No Clipping atBeam Combiner and at Mirror #1. 1. Open the Lid.2. Place Thermal Paper: Take a small

piece of thermal paper (approximately1 inch (25 mm) should be plenty) andplace it firmly over the Beam CombinerLens near the aperture side of theLaser Tube, Fig. 33.

3. Press the paper down with your fingerso that a circle appears thatdemonstrates the outer rim of thelens. Sometimes pencil lead or crayonwill help to show the edges of the lensand mirrors.

4. Close the Lid.5. Using the Touch Screen Display, test

fire the Dremel LC40 Laser Cutterfrom the Test Fire screen. The Firebutton will appear after all of thesystem checks have passed. Press thebutton one time and observe wherethe spot lands on the thermal paper.(From here forward called *Test Fire*)

6. The spot should be centered on theBeam Combiner Lens. Remove thethermal paper.

7. Repeat steps 2 – 5 at Mirror #1 (Fig.34).

8. The spot should be centered at Mirror#1 and not clipped by the BeamCombiner Lens. If it is not, there is aproblem with the tube mounting asthere is very little to adjust betweenthe tube and the mounting of Mirror#1.

9. Remove the thermal paper and cleanall tape residue from the BeamCombiner Lens and Mirror #1.

Spot should be centered.

Clipped spot indicates an

alignment issue.

TESTS & ALIGNMENTS

Step 4: Align Axis A-B (Y-Axis)using Alignment Laser's Red Dot.Conceptually, you will be aligning theinvisible cutting beam and the AlignmentLaser's visible red dot with the axis of theshaft from A to B. When the beams areperfectly parallel with the A-B axis, donot continue to change Mirror #1. Furtherchanges to Mirror #1 will then negate thealignment to the axis. 1. Open the Lid.2. Place Thermal Paper: Take a small

piece of thermal paper (approximately1 inch (25 mm should be plenty) andplace it firmly over Mirror #2, Fig. 36.

3. Press the paper down with a finger sothat a circle appears thatdemonstrates the outer rim of Mirror#2. Sometimes pencil lead or crayonwill help to show the edges of the lensand mirrors.

4. Move the Gantry to position B, Fig. 29.5. Close the Lid.6. *Test Fire* Observe where the spot

lands through the Lid. Withoutremoving the paper it may benecessary to mark this spot. This isSpot B1.

7. Adjust only the visible red dot tomatch the spot.

a. Do not move the Gantry at thistime, and do not adjust Mirror #1yet.

b. Using the 2.5mm hex wrench, makemicro adjustments to the threeadjustment screws of theAlignment Laser, and position thered dot exactly over the burn markat position B on Mirror #2.

c. If the red beam is not hitting themirror at all, it may be necessary touse a larger card or paper todetermine where the red dot is.

d. Go slowly and do not overtightenscrews. Small turns of the screwsare required to move the beam atlong distances.

e. It is best to align the red dot at thefurthest distances B and C to avoidsmall angle issues introduced at Aor D.

8. Without removing the paper, move theGantry to A.

9. *Test Fire*. If possible change positionto see if the test fire lands on thethermal paper without opening theLid. If it is not possible it may benecessary to use the suggested marksin step 6. This is Spot A1.If the two spots are exactly on top ofeach other, then the Y axis is aligned.Do not make any more changes to M1.Move on to B-C X axis alignment.

10. If the 2 spots are not on top of eachother at A and B, continue as follows:a. Move the Laser Head back to

position B.b. Note that the red dot can now be

used to predict where the nextlaser fire shots will be if it isaligned as in step 7.

c. While at position B, slowly adjustMirror #1. Not the red dot!

d. Change the mirror so that the reddot moves halfway toward SpotA1.

e. Leave the Gantry at B, Close theLid and tap *Test Fire*.

f. The new Spot B2 should havemoved toward Spot A1 and matchthe red dot.

g. If the red dot does not match thenew Spot B2, tweak the red dot(not Mirror #1) as in step 7.

h. Move the Gantry to A, close the Lidand *Test Fire*. Observe the newSpot A2. It should be only a littlecloser to Spot B1.

i. Note: If at any time spots becomeconfusing, shift the paper orremove it completely and startwith a clean piece. Spots will haveto be redone and *Test Fired* atboth A and B.

j. Continue this cycle of:i. Fire Spot B, ii. Tweak the red dot, iii. Fire Spot A, iv. Adjust Mirror #1 while the Gantry

is at Spot B,v. Until the spots created are

perfectly on top of each other.The spots on Mirror #2 may notbe perfectly centered, butshould certainly not extend off ofthe edge of Mirror #2.

Step 5: Align Axis B-C (X-Axis)using Alignment Laser's Red Dot.Alignment of the B-C axis is often mucheasier than the A-B axis due to proximityof the Gantry and experience learned onthe first axis. It cannot be stressedenough that the A-B axis should bealigned before attempting to align the B-C. As with A-B and Mirror #1, once B-C isaligned, do not continue to adjust Mirror#2. Further adjustment of Mirror #2 willnegate the alignment of B-C. 1. Open the Lid.2. Place Thermal Paper as before on

Mirror #3. 3. Move the Gantry to Position C.

4. Note that it is possible that Mirror #2can be adjusted far enough out ofrange and potentially damage therubber of Mirror #3 when the DremelLC40 Laser Cutter is fired. Look forthe Alignment Laser. It should give anindication of where the Laser Beam ispointing. Adjust Mirror #2 so that thered dot is hitting the thermal paper.

5. Close the Lid and tap *Test Fire*.Without removing the paper it may benecessary to mark this spot. This isSpot C1.

6. Adjust only the red dot beam to matchthe Spot C1. As this is the furthestdistance it will take extremely smallmovements of the screws to move thered dot.

7. Move the head back to position B.8. Close the Lid and tap *Test Fire*

observing and marking the spots asnecessary. This is Spot B1.

9. As before if Spot C1 and Spot B1 arenot exactly on top of each other adjustthe red dot using Mirror #2 this time toadjust the location of the red dot halfway to Spot B1.

10. See steps above and repeat this cycleof:a. Fire Spot C, b. Tweak the red dot, c. Fire Spot B, d. Adjust Mirror #2 while in position

until the spots created areperfectly on top of each other. Thespots on Mirror #3 may not beperfectly centered, but should notextend off of the edge of Mirror #3.

Step 6: Align Axis Lens holder (z-Axis) using Alignment Laser'sRed DotCentering of the beam on the lens is themost critical component of alignment.However, as the distance from Mirror #3to the lens is very short, it is difficult tomake drastic changes to the position ofthe laser spot. Resist the urge to adjustMirror #2 or Mirror #1, because asindicated before, it will only createmisalignment. 1. Open the Lid. 2. Place Thermal Paper: Take a small

piece of thermal paper (approximately1 inch (25mm) should be plenty) andplace it firmly over the lens.

3. Press the paper down with a finger sothat a circle appears thatdemonstrates the outer rim of thelens. Sometimes pencil lead or crayonwill help to show the edges of the lensand mirrors.

4. Move the Gantry to Position C. 5. Move the lens to its lowest position

using the Spacer Puck on theHoneycomb Plate.

6. Close the Lid and tap *Test Fire*without removing the paper as it maybe necessary to mark this spot. This isSpot L1.

7. Tweak the red dot to match the spoton the paper. Due to the reflections ofall of the mirrors the red dot may notmove with the same screw turns as itdid previously.

8. Adjust Mirror #3 continuing to test fireuntil the spot is nearly perfectlycentered.

a. Note: do not overly tighten Mirror #3. b. In rare instances, it may be

necessary to access the Mirror #3mounting screws.

c. Fully remove the lens holderassembly by loosening the LaserHead Knob, Fig. 37.

d. Loosen the two Mirror #3 mountingscrews (Fig. 38) enough to rotatethe lens in the direction of themissing spot. While holding the lens,retighten. The screws tend to rotatethe mirror in the direction oftightening.

e. Replace lens holder assembly. 9. After the spot is centered rerun the 4

Corners Tests. The spots should nowbe nearly on top of each other. Also besure to check that the Air Assist Nozzleis not clipping the laser path andadjust if necessary.

This product uses a laser beam to rapidlyheat, melt and partially or completelyvaporize the material, creating a number ofgases and particulate matter. Thesebyproducts of laser operation can, in somecases, pose health risks to those exposed tothem.To reduce or minimize exposure to theirhealth hazards, always use an appropriateexhaust ventilation and/or filtration systemand carefully choose your material. Whenusing materials other than those suggestedby Dremel, ask the manufacturer for theSafety Data Sheet (SDS) for each material.The SDS “Hazards Identification” sectionwill provide information to help determine ifthe material or its by-products are harmful.If the material does not have an SDS,consult the manufacturer to determine ifthe material generates toxic gases and/ordust, and if it presents fire or explosionhazards. Representative materials listed in Table 1may be used with a properly installed and

maintained exhaust ventilation and/orfiltration system when used as described inTable 3. However, these materials can varyin composition depending on manufacturerand other factors. Dremel has not tested allpossible combinations and not all materialshave documented health effects when usedwith a laser cutter. As such, the user issolely responsible for material choice andsubsequent health consequences. The Dremel LC40 Laser Cutter may be usedwith several exhaust management methodsto manage the exhaust created during laserfabrication. Always ensure the exhaustmanagement system is properly functioning.Refer to the Exhaust Management sectionon page 24 for proper exhaust ventilationand/or filtration methods. Exhaustventilation and/or filtration systems may notbe able to remove all hazardous substancesor reduce their concentration to acceptablelevels, so never use materials that areprohibited (see Table 2). Always checkhttps://digilab.dremel.com/ support/faqfor the latest material information.

OPERATING THE LASER CUTTER



Always use a properly configured, installed, maintained, andoperating fume/smoke exhaust system as recommended by the

manufacturer when operating the laser system. Caustic fumes and smoke from theengraving process must be extracted from the laser system and exhausted outside.

Always inspect the exhaust fan and duct work for obstructions andensure proper air flow exists before each use. Unobstructed and

properly maintained exhaust fan and duct work will reduce the risk of fire andeffectively extract caustic fumes and smoke.

Never engrave or cut any unknown material. Only engrave materialsrecommended by the manufacturer. The vaporization/melting of

many materials, including but not limited to PVC and polycarbonates, can give offhazardous fumes. Always refer to the Safety Data Sheet (SDS) from the materialmanufacturer to determine the response of any work material to extreme heat(burning/fire hazard) to prevent hazards.

Choice of material used during laser cutter operation andsubsequent health consequences are the sole responsibility of

user. Health effects of materials used may not be documented nor available.Discontinue use and seek fresh air if respiratory or eye irritationoccurs. Ensure ventilation, exhaust, and/or filtration systems are

working according to manufacturer specifications and make any necessaryadjustments before further use. Exposure to fumes may cause allergy, asthma,breathing difficulties or other adverse health effects.

Before the Dremel LC40 Laser Cutter canbe used, a project must be created. Theproject is then sent to the Dremel LC40Laser Cutter as a job and fabricationbegins. When done, the work piece isready for removal from the unit. Thefollowing steps cover the process frombeginning to end.Sequence of Operations:

1) Create a Project.2) Place work piece on the

Honeycomb Plate.3) Focus the Laser Head.4) Send the job to the Dremel LC40

Laser Cutter.5) System check.6) Run the Job.7) Finish the job.

Step 1: Create a ProjectProjects are constructed by opening theworkspace in the LC40 Control Softwareand importing a file (or files). The filesare available from (3) sources:A) Creating files in a graphics program.B) Importing previously created files.C) Using the camera capture feature.Most files are created through the use ofsoftware such as CorelDRAW®, AdobeIllustrator® or other graphic software.Depending on the software and how thefile was created, a project is developedto run a job that will allow the DremelLC40 Laser Cutter to cut, engrave and/orscore the material. Table 5 below listsseveral file types which can be importedinto the LC40 Control Software. Pleaserefer to the graphic softwaremanufacturer’s instructions regardingcreation of vector or image files.

Most designers use software such as CorelDRAW® or Adobe Illustrator® to create the designfiles to import into the LC40 Control Software, but pictures that have been taken with a cameracan also be used. Any software can be used that exports PNG, JPEG, PDF, or SVG files.

The LC40 Control Software accepts both vector (SVG or PDF) and image (JPEG, PDF, PNG)based files. It is best to think of “cut” and “engrave” separately when designing for theDremel LC40 Laser Cutter. Vector file types are optimal to cut something out of a material,or trace along lines with the Dremel LC40 Laser Cutter. Image file types are optimal toengrave into the surface of a material with various levels of intensity.

In order to use the file created in the design software, simply “save as” or “export” your fileas one of the above file types. It is best to save parts of the file that will have applieddifferent laser settings or applications to, as different files before importing.

By default, the LC40 Control Software will recognize different colors in vector files and allowthe application of different settings based on those colors. For a single image file, the sameprint settings need to be applied to the entire file.

For example, to engrave the dark area in this image in a dark shade, and the white in thisimage in a light shade, it is best to export the dark area and the white text and circleoutline as two separate files:

dark engrave (image file) + light engrave (image file) = light and dark engrave

A similar output could be obtained by bringing in a single image file and applying“grayscale”. In this case, however, the engraving will fill the object with tiny dots, rather than appearing solid.

Similarly, to engrave the dark area and cut out the white text, it would be best to save thetext outline as an SVG or PDF and the dark area as an image file:

dark engrave (image file) + text outline (vector file) = text and circle cut out

Multiple files can be sent to the Dremel LC40 Laser Cutter as a single job. Simply importmultiple files. If multiple files are exported from the same source file, the LC40 ControlSoftware will place them on top of one another by default.

Source C) On-board Camera Capture

There are two ways to use the cameracapture feature. The first way is to usethe camera to pull a picture of thematerial into the background of the LC40Control Software. Being able to see thesize and location of the work piece in thesoftware helps with aligning importedfiles, and reduces wasted materials. Thisis especially useful when wanting tocover the entire surface, to place a file inan exact location (center, near an edge orcorner, etc), or if it is a small piece ofmaterial. In order to use this function (Option 1):1. In the LC40 Control Software, go to

IMPORT menu. Click onIMPORT>CAPTURE.

2. Follow the on screen instructions —Place the material onto the center ofthe Honeycomb Plate and close theLid. Click “NEXT”.

3. The LED Lights in the laser will flashoff, and a red dot will appear. If thered dot is not on top of the workpiece, adjust the work piece and startagain with step 1.

4. The camera will then capture 9different images of the bed and stitchthem together.

5. Click “Done” to place this image intothe background of the workspace.

6. The background image can be clearedat any time by going to Import>ClearCapture.


76

Once the project file(s) are created theycan be imported into the Dremel LC40Laser Cutter and executed.1. Import, drag and drop a file, or use the

camera capture to begin a project.

Import PDF or SVG files for objectsyou would like to cut or score.Import JPEG, PNG, or PDF files forobjects you would like to engrave.More than one object can be sent tothe Dremel LC40 Laser Cutter in asingle job by importing multipleobjects into the same workspace.


The second way to use the cameracapture is to trace a drawing or sketch.For this application, it’s best to use ablack marker on white paper. Steps 1 - 4 are the same as in theprevious capture method.Follow steps 1 - 4 on previous page.5. Drag a box around the area of the

sketch that will be turned into a laserfile. Choose to make the selectionsensitivity higher or lower by switchingbetween the 3 threshold options andclick “next”.

6. Choose whether the file will beengraved or cut, and whether thebackground image should appear inthe software by toggling the switcheson or off and then click “done”.

7. The background image can be clearedat any time by going to Import>ClearCapture. The cut or engrave files canbe cleared by hitting “delete” on thekeyboard.

2. Select the material type and thickness.The material library will automaticallypopulate suggested cut and/or engraveprint settings based on the materialand thickness selected.

3. Move, scale, and adjust objects to thedesired orientation. More preciseadjustments can be made in thebottom left side of the screen.

4. Adjust print settings as needed. If thesettings are changed in this box, theywill override Dremel recommendedsettings until a new material isselected. The top right side of theprint settings box will unlock moreprecise setting options. Review joband job execution order to make surethe desired result.

5. Send the job to the Laser.

If you would like to save a job to yourcomputer to repeat again later go toFile/Save. The job will be saved in a .binformat and will contain each object, itslocation, and its print settings.

Step 2: Place Material on the Honeycomb Plate

Observe all providedwarnings and safety

instructions when using the DremelLC40 Laser Cutter. Failure to do so mayresult in fire, equipment damage,property damage or personal injury.

Never engrave or cutany unknown material.

Only engrave materials recommended bythe manufacturer. The vaporization/melting of many materials, including butnot limited to PVC and polycarbonates,can give off hazardous fumes. Always referto the Safety Data Sheet (SDS) from thematerial manufacturer to determine theresponse of any work material to extremeheat (burning/fire hazard) to prevent hazards.

Always use providedwork piece support

structure when cutting or scoring.Fabrication without Honeycomb Platemay lead to fire or release of strayradiation.

Do not use irregularlyshaped work piece.

Risk of stray radiation or fire.Do not stack workpieces. Stacking work

pieces increases the risk of fire.Place the work piece inside the laser onthe Honeycomb Plate, Fig. 43. Alwaysplace the work piece on the HoneycombPlate for cutting jobs. For engraving orscoring thicker pieces of material, theHoneycomb Plate can be removed andthe work piece placed directly placed onthe surface that supports the HoneycombPlate. If it is an irregularly shaped work

piece (such as a cylinder), place the workpiece anywhere on the laser bed and usethe camera capture feature in the LC40Control Software to align the design withthe work piece. Be careful not to damageany part of the machine during thisprocess. The Laser Head can be movedout of the way by hand if necessary, bypressing the “unlock” button on the LCDTouch Screen.Make sure the work piece sits flat on theHoneycomb Plate. If the work piece is notflat, the Laser Beam will be out of focus.If the difference in flatness of the lowestspot to the highest spot or your workpiece is more than 1/8" the Laser Headcould touch or move the work piece outof position. Depending on the job, thework piece can be aligned with the topleft corner of the Honeycomb Plate, orplaced at any location on the HoneycombPlate.


Fig. 43


79

Step 3: Focus the Laser Head

The bottom of the Laser Head must be atthe correct distance from the top surfaceof the work piece in order to cut orengrave a clean image. To focus the Laser Head (Fig. 44):1. Move the Laser Head so that it hovers

over your work piece, either bypressing the arrow buttons on the LCDTouchscreen, HOME menu, or bypressing “unlock” and moving theLaser Head manually with your hand.

2. Loosen the Laser Head Knob (left handside of the focus lens). Loosening theknob frees up the focus lens to moveup and down.

3. Raise the Laser Head and place theSpacer Puck between the Laser Headand the work piece.

4. Let the Laser Head rest on the SpacerPuck and tighten the Laser Head Knobto fix the Laser Head in place.

5. Remove the Spacer Puck.

Note: If the work piece to be engraved istoo thick to fit in the laser with theHoneycomb Plate, remove theHoneycomb Plate and place the workpiece directly on the surface thatsupports the Honeycomb Plate. However,this is only recommended whenengraving. Do not do this if the materialneeds to be cut.

Send the job file to the laser so the laser can perform its system checks. From theLC40 Control Laser Software toolbar click "START" to run the job.

Step 5: System Check

Review the screen to make sure that allfour system icons are white, indicatingthe system is ready to run.If any icons are red, the Dremel LC40Laser Cutter Touch Screen will notify youthat these systems need to be fixedbefore beginning the job. Touch the “?”next to the appropriate line item for helpdiagnosing and correcting each error.Refer to Touch Screen informationstarting on page 36 for additionalinformation.


Step 4: Send the Job to the Laser

Close the Dremel LC40 Laser Cutter Lid. The “Run Perimeter” feature on the LCDlaser screen or in the LC40 Control Software can be utilized to ensure that the workpiece and the design are aligned. The “Run Perimeter” feature moves the Laser Headaround the perimeter of the job as it is set up in the software.


81

Note: If an external ventilation system isbeing used, make sure that it is operatingbefore starting the job.Ensure tools and parts such as SpacerPuck, wrench, debris, etc. are removedfrom the Honeycomb Plate beforestarting a laser job.On the Touch Screen, verify that allsystem warning icons are still white.Press the Start Button twice to start thejob (Fig. 45).



Always use a properly configured, installed, maintained, andoperating fume/smoke exhaust system as recommended by the

manufacturer when operating the laser system. Caustic fumes and smoke from theengraving process must be extracted from the laser system and exhausted outside.

Never operate the laser cutter system without constantsupervision of the cutting and engraving process. Exposure to the

laser beam may cause ignition of combustible materials and start a fire.Always use the air assist as recommended by the manufacturer,especially while cutting. Cutting movements are relatively slow

and apply an extremely large amount of heat to the work piece. Avoid the build-upof heat in order to reduce the risk of fire.

Do not operate when access door is open. An open door can lead tostray radiation, increased exposure to hazardous vapors or burn

hazard.

Step 6: Run the Job

Once the job is complete, wait at least 30seconds before lifting the glass Lid andremoving the finished part and remainingmaterial from the Dremel LC40 LaserCutter.1. Verify that the Laser Head is not firing

and has stopped moving.2. Wait 30 seconds, and then open the

Lid to get access to the parts.

3. If the Laser Head is above the part,unlock the Laser Head by pressing the“Unlock” button on the HOME menu ofthe Touch Screen and then move theLaser Head to the top left corner byhand.

4. Carefully remove all pieces from theHoneycomb Plate. Be careful not todamage any part of the Dremel LC40Laser Cutter during this process.

Step 7: Finish the Job

Water Tank Maintenance1. Change water every 30 days to remove

particles and compensate forevaporation.

2. Check water level daily. Remove cap tocheck water level. Add distilled waterif needed.

3. Check to verify water is circulating byremoving the cap to the water bottle.Check daily.

4. Check water tank for mold. Clean withbleach if mold develops.

Cleaning Mirrors and LensesClean mirrors and lenses every 4 to 5hours of use. When using material thatproduces a large amount of smoke, suchas wood, cleaning is recommend morefrequently. Use extreme caution whencleaning the lens. If any scratches orpitting can be seen on the surface, thelens must be replaced. Theseimperfections reduce power and willresult in less energy reaching the workpiece.Contaminant left on the lens may resultin damage to the lens surface.Materials needed for cleaning mirrorsand lenses:• Finger cots or latex/vinyl gloves,

powder free.• Cotton tipped swabs or lens wipes with

alcohol free solution.Procedure for cleaning the focus lens:1. Remove the lens from the lens holder,

Fig. 46.2. Dip the swab or lens wipe in the lens

cleaner solution, use a gentle circularmotion to clean the lens surface.

3. Use dry swabs or wipes to gently drythe lens surface.

4. Reassemble the focus lens in the lensholder.

Procedure for cleaning mirrors:Never remove themirrors for cleaning.

Take extra caution to not move theorientation of the mirrors as this willaffect laser beam alignment and wouldrequire time intensive laser beamrealignment.Remember to check alignment aftercleaning the mirrors.

Procedure for cleaning the Laser Beam Aperture and Beam Combiner LensThe Laser Aperture and Beam CombinerLens should be cleaned every 4 - 5 hoursof use. For locations of the Laser BeamAperture and Beam Combiner Lens, referto Fig. 2, page 17 and Fig. 47.1. Cleaning the Laser Aperture and Beam

2. Do not remove the Beam CombinerLens. The Laser Aperture cannot beremoved from the laser tube. Be extracautious when cleaning the LaserAperture. Any damage to the LaserAperture will result in a damaged lasertube.

3. Dip the swab or lens wipe in thesolvent. Use a gentle circular motion toclean the surface of the Laser Apertureand Beam Combiner Lens.

4. Use dry swabs or wipes to gently drythe surface of the Laser Aperture andBeam Combiner Lens.

5. Reassemble the Laser Tube Guard.

Guide Rails X and Ya. Clean the X and Y guide rails weekly.

Clean more often if debris is visiblyaccumulating.It’s important to keep the left and rightside rails clean to allow the movingparts of the Dremel LC40 Laser Cutterto glide freely without sticking orbinding. Also, clean the guide railbetween the two side rails supportingthe moving Gantry. Keeping these railsclean is important to maintain the highprecision of the Dremel LC40 LaserCutter.

b. Use a clean soft cotton cloth to wipedown the rails. Re-lubricate with alight coating of white lithium grease.

Enclosure and Top CoverThe enclosure and glass Lid for the lasershould be cleaned at least monthly.Cleaning the enclosure:• Wipe down the external surfaces of the

enclosure with a soft cotton towel. Uselight pressure to avoid scratching thesurface.

Cleaning the glass Lid and side covers:• Use glass cleaner and a soft towel to

clean the Lid.• The plastic side covers should only be

cleaned with glass cleaner or a mildsoap solution. Use a soft towel andlight pressure. Do not use a papertowel, as this is more abrasive and canscratch the surface. Do not use alcoholto clean the plastic side covers.

• Use caution when cleaning the displayscreen as it is made of glass. Use lightpressure.

Cleaning the interior:The interior of the Dremel LC40 LaserCutter should be kept clean of debris.Check at least once per week and clean ifnecessary. Keeping the interior clean willreduce the risk of particles flaming duringuse and will reduce the chance ofairborne dust interfering with the laserpath.• Remove the Honeycomb Plate and wipe

or vacuum the interior clean of anydebris.

• Pay particular attention to the LaserTube Guard as the small outletopenings can become clogged withdebris.

Y-Axis Beltsa. Checking belt tension. Check the

rubber belts for tension every sixmonths. The rubber belts worktogether to move the Gantry front torear. It’s important that they haverelatively the same amount of tension.

MAINTENANCE

Tension is difficult to measure butthere should not be sagging in one beltand complete tension in the other.Laser Cutters are delivered with theproper amount of belt tension. It isadvisable to check belt tension whenthe Dremel LC40 Laser Cutter is newto establish a good baseline for futurereference. Simply depress the beltlightly with your fingers and note thedeflection. The belt should deflectabout 1/4-1/2 inch with a light force.

b. Tensioning the belt. Push on the idlerpulley mount by hand to loosen thebelt and to ensure the spring loadedpulley is free to move and not binding.Moderate to strong force isrecommended. Tighten or loosen theidler pulley tension screw using a1.5mm hex key (not supplied) asnecessary. Repeat for the oppositeside belt.

Exhaust FanDo not try to cleanexhaust ducting. The

high concentration of particles maybecome airborne and create inhalationexposure.a. Clean the exhaust fan and ExhaustShroud.After prolonged use, the fan performancecan diminish due to dust build up on thefan blades and Exhaust Shroud. If thelaser has been used for a lot ofwoodcutting, cleaning will need to bedone more frequently. Debris can stick toany surface in its path. If fan noise orvibration is detected, a cleaning isrequired.Disconnect the exhaust duct from theExhaust Shroud. With a clean soft cloth,wipe the inside of the Exhaust Shroud toremove all residue. With a soft cloth,clean the dust off the fan blades. It willbe necessary to remove the fan from theenclosure.b. Inspect the exhaust duct.Periodically inspect exhaust duct forwear or damage. If any duct appearsworn, constricted or damaged, replacebefore further use.
