CoreXY Laser Engraver Mk2

thingiverse

I've been working on an upgrade for the original engraver. When Jogi posted his Make of the original version (https://www.thingiverse.com/make:523254) he improved on many shortcomings (much cleaner build, larger area, chain belts) and we began discussing about a Z axis implementation. It took quite a while but here's now the Mark 2 engraver with a motorized Z axis iwht 50 mm effective travel range. The Z axis can for example be used to find the optimal laser focus by scanning a certain height range. You can also adjust your focal spot on a sacrifical layer on your work piece and later correct for its height by using the Z axis. And, of course, you can engrave 3D surfaces. although this probably requires a proper CAM software. I will add more details in the future and generally report on the new design.
