PLA bushing sliding on precision ground 8 mm rods is actually quite smooth movement. I don’t think it can go as fast as the original Sells Mendel (which was ball bearings sliding over the rods), but it’s only half the printed parts and the z-axis is much smoother motion too. I will try oiling or greasing the bushings to try to get smoother and faster motion without losing steps. So definitely some tradeoffs but overall a super awesome bot. The Prusa is also fully parametric and entirely made from OpenSCAD. All sources are available on github FTW.
As this is the first bot I built that I actually own, I named this awesometown after my HS science teacher, Mr. Sloate, who really got me into Biology and now, robotics for Biology.
What will we print next?
