OK, next challange:

I'm now trying to tune my motors and am thinking the following:

My steppers are 1.8degs and I am assuming this is 1.8degs per step, which would mean 200 steps per revolution (360/1.8=200)

My ballscrews are 1605, so again an assumption that 1 revolution of the ballscrew is going to translate to 5mm linear travel

So I am thinking that to get the number of steps per mm for Mach3 I am going to have to set the motors to 200/5=40 steps per mm?

Not sure what the velocity should be set to or acceleration in that case, but I guess I can play with the sliders and get the motors running "smoothly" and not stalling.

Again any advise welcome.

Cheers


Chris
