Gearing Down the Arms
05/31/2016 at 00:08 • 0 commentsThe long arms in the delta mechanism amplify the quantization from the stepper motors, resulting in ridges on the surface of printed parts. To combat this effect and increase print resolution, we added 5:1 gears to the motors using GT-2 belts. The roughly designed prototype:
This modification was a total success, there is no discernible "ridging" from the motors anymore. The new mechanism in action (but out of frame).

Initial Build

Success! A working printer!
