The SainSmart Genmitsu Jinsoku LC-40 rotary doesn’t come with much documentation for using it with LightBurn, so I walk through how I got it working.
I flash the firmware, enter the GRBL commands in the LightBurn console and set up the rotary settings, including mm per rotation and roller diameter. I also show how to switch back to the standard GRBL settings.
Getting the GRBL commands and settings right is what makes it work, so I share the specific values I used. The files from the video are linked, too.
Once it’s set up, you can engrave cylindrical things like rolling pins and tumblers.
