i'm about to test my cnc machine this week.
i've set the stept per turn to 160 (because i have a ballscrew that moves 1.25mm per turn -> 200 steps / 1.25mm = 160 steps per turn when not using microsteps).
-> question 1: is this O.K. or is microstepping with 1/2 or 1/8 better?
also i'm using these motors: "57BYGH56-401A Single-Shaft Stepper Motors 1.26Nm/175oz-in 2.8A" and this controller set: http://www.benl.ebay.be/itm/18084063...84.m1423.l2649
-> question 2: so i'm wondering what to set the 'velocity' to without overheating the motors or controller?
this probably also depend on the material i'm cutting or not? i am about to use the machine mainly for cutting PVC plates...
thanks in advance!!
