CoreXY Laser engraver

Over the Christmas break, I wanted to create a small laser using materials I had in the drawers already. I was inspired by other designs on Thingiverse. Neither of them was fit for my use case and I ended up creating a new design using OpenScad.

The controller board runs FluidNC with WebUI v3 enabled, that provides a nice interface you can access via a web browser from your PC, tablet of phone. Upload files to the SD card and repeated cuts becomes very easy.
