Inkscape Laser Tool Plug-in

The folks over at Inkscape have developed a very good vector editing software program that also allows for extensions.  We have updated and modified the original laser engraver plug-in to allow for multiple versions of on and off commands for different printers and CNC machines.  If you are installing the newer version of 0.92, I would suggest making a clean install or you might run into problems.  Just uninstall your older version before upgrading.  We have both versions listed below.

For Inkscape version 0.92:
To download Inkscape:
Click here to download the plugin:   J Tech Laser Tool Plugin V 2_2 for inkscape 0.92

For Inkscape version 0.91:
To download Inkscape:
Click here to download the plugin:  J Tech Laser Tool Plugin V1_10 for inkscape 0.91

This plug-in will convert a path object in inkscape into a G Code file for use in your laser upgraded machine.  Put the contents of this .zip folder into the “inkscape\share\extensions” folder.  Once it is there it will show up under the “extensions” tab in inkscape.  If you are on a mac, here is how to install the extensions:


The new plug-in allows for multiple commands for laser on and off for all the different versions of printers as well as the ability for multiple passes for cutting.  Here is a description of the features of the plug-in.

  • Laser ON Command:  The command for turning ON the laser.  For example, M03 or M106.J Tech Laser Tool inkscape picture 2
  • Laser OFF Command: The command for turning OFF the laser.  For example, M05 or M107.
  • Travel Speed:  The speed of the machine when the laser is OFF in mm/min.
  • Laser Speed:  The speed of the machine when the laser is ON in mm/min.
  • Laser Power: If you have PWM control, then you can adjust this.  For J Tech firmware and most 3D printers use a number between 0 and 255 (255 being full power).  For GRBL 0.9 and 1 standard, use a number between 0 and 12000 (12000 being full power).   If you don’t have PWM, keep at max power (either 255 or 12000).
  • Power On Delay:  This will turn on the laser and wait to move until the delay is complete.  It is used to heat up the material and initiate the burning process.  Delay in ms for 3D printers and seconds for GRBL.
  • Passes:  If cutting, this will repeat the entire path by the number of passes.  If engraving leave as 1.
  • Pass Depth:  This will move Z axis down by this amount for each pass.  For example, 3mm piece of material with 3 passes might use 1mm per pass to cut all the way through.
  • Directory:  The directory to store the file.
  • Filename:  Name of the file.
  • Add numeric suffix to filename:  Adds a number to the name in case there already is a file with the same name in the directory.
  • All Units: Change the units to either mm or inches.  This will make everything in inches or mm.
  • Live preview:  Shows the path being generated.
  • Apply:  Click to run the converter.

Using the Plug-in

We have made some instructions on how to use Inkscape for engraving text and other objects and using the plug-in to generate the G Code.  We have also shown how to import images to make outlines of them to engrave.
