M2 ASSEMBLY GUIDE
2. BUILDING THE FRAMEThe Frame has 2 main parts: The Top Beam that holds the motors (we recommend attaching it to a wall) and the Wasteboard on which you will clamp the material you want to the M2 to cut.
The size of material the M2 can cut is only limited by the chain length. These instructions are based on the chain included with your M2 and will walk you through how to set up your kit to cut material as large as 4’x8’.
STEP 1Measure wall studs for Stud Mounts that will hold the Top Beam
STEP 2Attach Stud Mounts to Top Beam, at measured distance of wall studs. Then attach Top Beam to wall, aligning Stud Mounts with Wall studs.

4. MOUNT ARDUINO DUEAt the M2’s core is an Arduino DUE microcontroller. We recommend mounting the DUE to the wall behind your Wasteboard, but it can be mounted in any safe location where it won’t be stepped on or conflict with the M2 during operation.
Note:Unfortunately, with the initial version, the hole for the MicroUSB is for the wrong port. You will need to remove the DUE and mount it without its case, or modify the case to plug in the MicroUSB into the covered hole. We apologize for the inconvenience and appreciate your understanding, here’s a video of the quick fix!
With Case Without case (notice how the “DUE” written on the board is upside-down, that is the orientation for these instructions)
STEP 1:Using included screws, mount Control Board in its case to wall behind Wasteboard

M2 ASSEMBLY GUIDE
Warning: We recommend wearing safety goggles and having a friend help mount the sled to the frame. The chain can snap back causing damage to self and surroundings.
STEP 1: Hold M2 sled against the Wasteboard near the spring and hold it against the frame with your body weight.
STEP 2: Take the loose end of one chain and thread through hole in the Roller Bearing Carriage built in Step 1 of Mounting Sled Brackets.
Insert cotter pin to attach chain to M2 into second to last chain link.
5. ATTACH M2 TO FRAME
STEP 3:
Move M2 to center of Wasteboard and have a friend pull the tension on the opposite chain to a length of 20” or less (from the nail to the spring). You can pull the chain away from the spring and lock onto the top of the motor for the tension to hold.
When you have enough slack in the chain, thread through the opposite Carriage Mount and attach with a cotter pin.
Let go of the sled and it should rest against plywood or MDF. Your M2 is ready to calibrate!
Warning: Beware of chain tension! We recommend a friend help connect the spring and each person wear safety goggles during stretching. The chain can snap back causing damage to self and surroundings.

M2 ASSEMBLY GUIDE
CALIBRATION & OPERATION
After the frame is built and the M2 is assembled, you are ready to use your new CNC! This guide is for using standard bit diameters and does not cover V-bit usage. To better understand CNC, we recommend reading through this whole section before beginning the calibration process of the M2.
EXPERIENCED MASLOW USERSThis section will be covering calibration with Makerverse 1.0.6.
You will have to set your Z Step Per Rotation to 472.5 for Easel, by inputing $102=472.5 in the console, the Z-axis is already swapped. You will also have to measure your actual X/Y cuts, the distances between your motors, and the distance from the chain to the Wasteboard. The process is explained below.
BEGINNER TUTORIALTo use your M2, you will need a digital file, CAM (compter-aided manufacturing) software to create the Gcode program the M2 will follow, and a machine control application to send the Gcode to the M2. This quick tutorial will show you how to use CNCjs, a machine control software, and Easel, a Gcode generator, with a digital .SVG file.
GET A DIGITAL .SVG FILE
1. Digital file: You must have a digital file to CNC with the M2. We suggest a black and white SVG file. There are many files available online and tutorials on how to create them on YouTube!
2. Create a file: You can download an SVG file or create one yourself using Inkscape, found on your flash drive.
USING CAM SOFTWARE
1. CAM software:We suggest using the CAM program Easel to create your Gcode. Create a free Inventables account and login here to use it.

M2 ASSEMBLY GUIDE
2. Open file:Once you login, load your design by clicking “File” > “Open” and selecting your .SVG file.
3. Choose depth:Click on your file and “cut” tab in the dialog box to choose how deep the M2 will cut. If your SVG is split into multiple parts or isolatable, you can select different parts of your file to cut different depths.

6. Change BitChange the bit settings to the same bit that is on your router. Click the “bit” tab and select your bit.
There are preset bits for the X-carve, but the best way to change it for the M2 is to scroll to the bottom of the tab and manually type in your bit size.

M2 ASSEMBLY GUIDE
7. Change depth per passThe safest and cleanest way to have a clean cut is to change your depth per pass to half of your bit diameter. Here, we have a 1/4in bit, so we changed our Depth per pass to 0.125 inches. You can leave the other values as they are for now.
8. Arrange:When you create your gcode, your M2 will start cutting your file based on where X,Y both equal zero millimeters (0,0). You can arrange your file to start based on where you home your M2. Either select and move all the parts of your file or click the “shape” tab in the dialog box after selecting your model. Click the bubble in the five part matrix to choose where your M2 will start. The bottom corner of the grid is (0,0), and will correspond with where you set (0,0) home in your Machine Control Application for your M2.

3. POWER:Ensure your M2 DUE Board is plugged into power and the USB to your computer.
*See Chapter 3: Assembling your M2 and be sure your motors are connected!
ATTENTION: When connecting your M2 for the first time, be sure to be close to a power source to unplug if anything does not go as planned.
If the X, Y, and Z motors are not plugged in completely to the motors and Arduino DUE Board, the M2 will not follow your commands and will act wonky (like continuing to move when you only told it to move 1 inch).

1. DOWNLOAD: You need a machine control application (also known as a Gcode sender). We suggest our Makerverse for your M2 and many other CNC machines. It’s based off the open source CNCjs software. Download it for your Windows, Mac, or Linux computer here: https://makermade.com/m2-resources/
2. OPEN MAKERVERSE: Click “allow program” to open. It is pending release in the Windows and Mac App Stores. An account is not required, but you may set one up later.

6. VERIFY CONNECTION AND ENTER Z-STEPSYou will know your M2 is connected when you see the Grbl Gcode readout in the Console, shown below. If you don’t see lines of code, then your M2 is not connected. To disconnect at any time, click close.
You will also have to set your Z Step Per Rotation to 472.5 for Easel, input $102 = 472.5 in the console and press enter. These commands will only have to be entered once.
7. UNLOCK:Because the M2 is an omni-directional CNC without endstops, the “Alarm” is active and must be unlocked. Click the yellow “Unlock” button in the top right corner to start the calibration process. The console will confirm the machine is unlocked.

10. HOME TO (0,0):The home position must be set on your M2 before you can CNC or jog your motors. If your sled is not already in the center of your wasteboard, click the Set Home command and move the M2 sled and chains to the center of your wasteboard using the X-, X+, Y-, and Y+ jog commands on the right.
NOTE: Home must be set before you attempt to jog. If you try to jog before setting home, the sled will continuiously move in the direction you clicked until you unplug the DUE Board from power.

Once the M2 is moved to the center, click the blue “Set Home” button to set home. X, Y, and Z are now set to zero (0,0,0)on the M2 and will be remembered on the M2’s internal memory. You are now able to jog your M2!
11. SET Z-HEIGHT:Set the height of your bit to touch the surface of your material, so it will cut the depth you choose in your CAM software. To set, change the units to “1mm” and click the “Z-” until your bit is barely touching the surface of the material you want to cut. Click the Home in the Z Axis position to set the new Z-height on your M2. You are now ready to load your Gcode into CNCjs and start cutting your project!
The home position must be set on your M2 before you can CNC. To home, move the M2 sled and chains to the center of your wasteboard using the X-, X+, Y-, and Y+ jog commands on the right.

12. UPLOAD GCODE:Click “upload Gcode” and select the Gcode file you created in Easel.
You’ll know your Gcode loaded correctly when CNCjs displays the paths of the Gcode you loaded! You already set the dimensions and depths in Easel for the M2, so it’s ready to start! We recommend a one foot or one meter square as your first test cut for calibration.

13. START:Before you cut, raise the Z-Height 3mm above your print surface (so it doesn’t start touching your material). Put on safety goggles, set your router RPM to the recommended cut speed for the material, manually turn on your router so your bit is spinning, and click “Run” to begin cutting out your project! We recommend running the first cut with the router off to ensure everything is running properly.
When your M2 is cutting for the first time, be close to the power source to stop all opperation if something goes awry. After your first test cut, you will measure and compare the real values to the values of your Gcode for scaling, described in step 16.

14. PAUSE/STOPTo pause or stop the M2, click the “Pause” button on the top bar. Once the M2 is paused, you will be able to stop the project by clicking the “Stop” button next to it. It must be paused before you can stop the project!
15. WORK POSITION:When working on projects, setting and changing your Work Position Home will make using your M2 more fun and efficient.
Once you home your M2 out of the box, we recommend changing your Work Position (0,0) for projects, instead of resetting home every time you are cutting a new project. This will save time and calibration headaches!
For example, to use every part of your 4’x8’ material you can set different work positions each time you cut with your M2. Then you could cut the same project out of different sections of your material!
To set the work position, jog the M2 to the position on your material where you want to begin. Then click the “Zero Out Machine” locator icons for X and Y under Machine Position to set your new Work Home.

Now when you run your M2, you can begin from where you set your temporary home position! We recommend cutting 3 or 4 times and measuring until your cuts are near exact to your Gcode.
You now know how to start making projects on the M2. Happy making!
16. MEASURE CUTS AND SCALINGAfter your first cut, measure from the center of the cuts across the X and Y Axis and compare it to your Gcode file.
Enter the X values in the X Scaling.
Then enter the Y values in the Y Scaling.

TIPS & SAFET Y WARNINGS
We recommend attaching a hook to the Top Beam to hold the M2 when not in operation.
Always wear safety goggles.
Always clamp the material you’re cutting to the Wasteboard Stud Mounts so it doesn’t move during operation. You can also securely attach it to the Wasteboard using screws.
Always raise the Z-Height to 3mm above your print surface before you turn on your router and run your M2.
Never leave your M2 unattended while in operation.
Always pause your M2 before stopping your M2 in CNCjs.

M2 ASSEMBLY GUIDE
CNCjs does not control your router, it only controls your M2. You must manually turn your router on and off.
In case of an error always turn off your router before you turn off your M2.
Always remember to turn on your router before clicking “Run” in CNCjs and turn off your router after the M2 is paused, stopped, or has completed the project.
It’s a good idea to make sure you’re behind the waste board when you declamp materials, as they can fall to the ground on your foot. Nobody wants that.
When installing the frame, we recommend a friend help connect the spring and each person wear safety goggles during stretching. The chain can snap back causing damage to self and surroundings.
