Yep. That's what I was looking for.

Can we have a folder where members can discuss some of the mechanical aspects of printers? Here's a problem I want some help with:

I'm chasing some comments on the degree of accuracy of extruder movement we should be chasing. I want to know how finely tuned the movements have to be to produce an acceptable product. I want to put a "cotton reel" on a 1.8 degree per step motor. If the cotton real has a radius of 7.95mm, then at the circumference, each step makes an arc 0.25mm long. Would that be accurate enough for movment in the X & Y axes?
