Benefits of Belt Drives for Steppers

[Tool-n-Around]

Are you building a moving gantry type machine or mill?.

Gantry. Considered Moving and Fixed Gantry, and Moving Table, but moving gantry seemed to best fit my goals.

Hi Kelly welcome to the forum, this is exactly why you should share/start a build log, your design doesn't have to be novel but it will be interesting to allot of us, we can focus on the construction aspects together and maybe learn from each other too :).

I'll see what I can do but am pretty far along. The Z is built. Most of the linear motion components are in hand or on order and design fairly well committed. Motors, drives, machine controller not yet committed but fairly far along yet I must confess, still learning.and plenty of room for learning and input there. Here's teaser on the Z.



Best,
Kelly

I always use belt reductions to get 5um per half step, tuck the motors out of the way and keep the hand wheels. I round every movement out to 0.005mm. Works for me.
Thing is my latest mill conversion has steppers and DRO's. Not a problem unless the stepper controller can read the DRO's. I couldn't resist...
What will I have it do when the motor disagrees with the DRO by >0.01?
