Repetrel 3D Software

Printing Basics

Repetrel is a robust 3D Printing Software developed by Hyrel. Repetrel is a based on the Repetier

platform, has embedded Slic3r software, and we provide in-house recipes to optimize your 3D Printing

experience. Our research and testing of how different printing variables affect different materials

allows us to provide you with a large number of unique Slic3r Recipes to use based on your needs. You

can choose the default recipes we provide and recommend, but you can also create custom recipes

based on special or complex build requirements, materials, work environment, etc.

The following two pages detail our naming conventions for different Repetrel Screen areas.

The first diagram is the first page that appears in Repetrel. We informally call these areas by their

physical screen location.

• Main Top Menu Bar

• Left Side Window

• Right Side Window

The second diagram details out more specific items and areas of the Repetrel Software. The Right Side

Working Area Window is where you Open STL and GCode files, Select Recipes and Process STL files for

Slicing, ultimately generating your GCode file. You also have options for manipulating your 3D Object

with regards to size, position and orientation to the build platform. There are more advanced options

on the right side where you can view, search, and edit GCode data instructions.

The Left Side Window contains two frequently used tabs: the 3D View Tab for viewing 3D STL and

GCode Objects in different perspectives, zooming in an out, and use your mouse to navigate and move

your object freely on the bed. The Control Tab view displays options for controlling and configuring up

to four print heads and your heated print bed platform. We configure your printer to work out of the

box, but you can also verify and dial in your print bed and print heads to ensure all settings are correct,

including: Tramming (Leveling) your print bed, Calibrating the Z Height distance between print head

nozzle and print bed. You can even Fine Tune the Z Height as your first layer is printing, if needed.

The goal in developing Repetrel was to provide a single access page for the most common tasks. Many

of the areas will not be used as frequently, especially for new prints. This document lists the steps

required to perform basic printing steps and a quick communication check if needed.

This document will illustrate screen areas, buttons, tabs, pull down menus and basic tasks required for

printing. For simplicity, we are listing the basic printing steps.

Printing Steps for Hyrel System 30 using Repetrel Software

Repetrel requires a configured GCode File to send the print command to the 3D Printer.

The following Repetrel Steps are required to convert an STL File in to a Printable GCODE File.

1. Open an STL File in Repetrel to prepare for 3D Print.

a. Go to the Right Side Screen, Select Project Composer Tab.

2. Click the Pull Down menu, then path: Add STL File => Open STL

3. The default directory for Repetrel First Prints using STL Files should appear.

• If not, navigate to C:\Repetrel\First Prints\stls\



4. Click to select the STL File you will use, then Click the button.



The Repetrel window will appear.

Your STL File appears on the Object Tree. The 3D Object appears in the 3D Tab View.

Note: The (0,0,0) origin of your STL file will be centered on the (0,0,0) origin of the Build

Platform.

5. To Center the STL Object File:

a. Click the tab, then Click the Bullseye button.



Note: The3D Object now should be centered, if your model was centered about the (0,0,0)

point. If not, Right Click on the physical object and hold and drag the Object to the center or

change your OffSets values manually.

In order to Print, we need to generate GCODE File from the STL. The first step is to Verify and Select

the SLICER Recipes specific for your print. Repetrel comes with default recipes for different materials

including ABS. If your recipes are not already saved by default or you have changed them, correct

them and save the Recipes by clicking Save As Default.

SLICING the STL File

Slicing the STL File takes the STL File with your selected recipes to create a GCODE file.

To Slice your STL file take the following steps.

1. Click the SLICER Tab .

2. The Repetrel / Slicer (Slic3R) Recipes selection boxes will appear.

3. If you have not selected your recipes, Select the items listed below before SLICING.

• Select the Pulldown menu Buttons for each of the fields above.

• Scroll and select the correct recipes for the material you are printing with.

• For an ABS Print, the defaults recipes should read as follows.

Print: HYREL Z.2 S1800 noSprt

Printer: HYREL 30M

Extruder 1: HYREL ABS 230c Fan 50%






Note: If you are printing with just one print head, it is only necessary to enter the recipe

for Extruder 1. Ignore Extruders 2, 3, & 4 for Single Head Prints.

• Click the button, to save your settings for later prints.

4. Click the pull down menu, then Click Slice with Slic3r

The following progress window appears.

Once the Slicing Process is complete, you will notice two things:

• Text displaying “Exporting GCODE to

C:Users\(User Name)\Documents\Slic3rOutputFile.GCODE”.

• Repetrel adds the GCODE File to the Process Tree, just below the STL File.

You would rarely have to Kill Slicing Process, other

than to redo a step you missed.



• Your GCODE Object appears overlaying the STL File with different color and opacity.



5. Click the button.

• Repetrel will process all of the information to send to the printer.

• Repetrel will indicate “Writing Print Job”.

• The Print Timer begins, showing progress toward your Estimated Print Time.

The example below shows an in process print, already printing 50:25 minutes out of a 6 hours.

When the print is complete, Repetrel will automatically turn the heat and power off to the Print Head

and the Heated Build Platform, if you use our recipes.

The following sections detail how to check and if needed, troubleshoot communication problems

between the Tablet/PC and the System 30 Printer.



Checking Communication between Tablet/PC and Printer

When you Open Repetrel, if Repetrel sees the printer, you will receive confirmation in the Log File

Display Screen (Hyrel Printer Found, SW REV.Hy: Rev_2.414), indicating communications between

Repetrel and the Printer. The Rev_2.414 indicates the Printer System Board Controller Firmware

revision number. The first line lists the Repetrel Version number (Repetrel v2.855).

If “Hyrel Printer Found” confirmation does not appear in the left Log Window, try these quick checks.

1. Click the Button pull down menu, then Click Turn Light On.

a. If the Printer Bed Light turns on you are communicating with the printer.

2. Also, Under the Control Tab, Repetrel will recognize the Print Head and the Print Bed, and you

can power both on and off.

If the light does not turn on and you do not see the Print Head and Bed, see troubleshooting steps on

the next page.



Troubleshoot Communication problems between the Table/PC and 3D Printer

1. Click the button in Repetrel (Top Right). Then repeat the Light check above.

If you still are not communicating with the printer, try the Comm Link Tab.

2. Under the Right Side Sub Menu - Click the Tab.

a. Click the button and click REFRESH.

b. Click the button and select the highest Com number.

c. Click the Baud Rate button and select 38400.

d. Click the to save your settings.

e. Click to send a communication test to the printer.

See confirmation message in the text box, confirming “Connected to Printer”.
