Hello there. I made a mod for my broken Mega Zero 3d printer. This mod will give your old Mega Zero (v1) printer a new life. This will convert one into a Pen Plotter. I removed the hot-end, fan, and other things that generated heat and turned off those settings in cura. I screwed in the mount where the extruder used to be with the original screws and used a zip-tie to stabilize the pen to keep it from wobbling. Use 2 m1.7*5 screws to hold a pen or another drawing/writing utensil in place. Clips and tape should help hold the paper in place. I can share my cura settings if you want.
I followed some of the instructions from this video by: Hackbatch, but changed some settings for my own printer.  Do this mod at your own risk.
