A remix of the ZDV LASER ENGRAVER.
All structural parts should be printed with PETG or something more stable. Minor parts can also be printed with PLA. Prusa filaments work well for both. No supports needed. 0.2 mm per layer works well. Finer resolution not needed. Further Explanation for assembly and firmware configuration can be found here: https://www.zhildv.ru/zdv-laser-engraver-v2/
