ok so is the 1600 we were setting using the switches witch on the side of the driver refers to as step/rev is the same as in pro tune when you set the micro step?

many thanks

Ok I think I see your confussion Charlie.? There's 2 ways to describe the same thing.!
Some will say 4X 8X 16X etc which is technicly more accurate and this relates to the amount of degree's the stepper motor gives per revolution multiplied by the number.
Other way just assumes typical 200 steps per rev and gives total micro steps per rev.

IE typical stepper uses 1.8 degree or 360/1.8=200 steps per revolution. So 4 x 200 = 800 micro steps per revolution
If you used 1.2 degree steppers then it would be 360/1.2=300 so 4 x 300=1200 MicroSteps Per Rev

The Drives show typical 200 steps per rev on the front but the protune uses the more correct multiplication factor. so if you want 1600 micro steps you'd use 8 in protune.
