AdCNC - Now that your machine has been running a while ... i appreciate its servos not steppers ... but any comments / after thoughts on belt size/pitch/width/type, gear size/material, ratios or the design you used to allow for tension adjust?

If you remember .. what were the specs of the belt + pulleys you used?

BIG THANK YOU!
