neat and distinct appearance. can you apply the coating to other surfaces than paper? If this works for hard objects like ceramics and metal, you could make some neat decorative items that way.

FWIW I had pretty good results upgrading my lasercutter to 32-bit with a Panucutt Re-Arm board as the main controller, hosting Smoothieware. Lightburn works fine with it. I had so many buffer problems with the original 8-bit configuration. Engraving and cutting all works a lot better and it wasn't too difficult to get to work. Also it was a reversible hack since I retained the original driver board talking to the steppers and the HV laser module. However, I've never managed to dial in any semblance of good gradient / exposure intensity control.

this may be too obvious, but have you considered exposing the plates using the UV backlit LCD of a resin 3D printer? You can buy UV modules with collimators and 8K panels pretty cheap. Of course that would produce a fixed-resolution pixel grid as opposed to the variable pitch raster exposure mode you have now.

There is also perhaps the question of what flavor UV you need. I think resin 3D printers expose with UV-B light, and that's what those lamp modules and collimating fresnels are designed for. What's the spec on your UV laser?
