Designed in Solidworks, rendered in Keyshot
H-bot belt drive (XY motors don't add weight to the extruder, they act at a distance)
Inductive sensor for automatic bed-leveling for each print
Heated bed (no more warped parts!)
Strong cooling fans to cool the extruder and the printed part
Sturdier, lighter construction of gantry enables much faster printing
Overall lighter, more compact, and still inexpensive
In the interest of working on more urgent projects, I am reluctantly postponing work on this project. I still really want to finish this!!
