Hi,

I have settings set sw 1 ON sw2 ON sw3 OFF, sw4 I left off and then I thought I needed to set sw 5 6 7 8 25600 not sure where I read something about that so OFF OFF OFF ON for SW5 thru 8.

That does not mean that much to me, these are your stepper drivers, you have them in front of you. You have to use the

driver instructions to determine what that means.

If your microstepping regime is 25600 steps/rev its unrealistic.

You need to set the switches for 8 microsteps per full step or 1600 steps/rev. Note that 4, 8, 16 or even 32 microsteps

per fullstep would be adequate. Adjust the following calculation to suit if you choose other than 8 microsteps.

I assume because you have metric ballscrews that your native units are mm?

Then you steps per unit, which you put in the motor tuning page would be:

1600 (steps/rev)/5 (mm/rev)=320 steps per unit

I would set, as a preliminary estimate, a max velocity of 500 rpm or 500 X 5 =2500 mm/min

I would set, as a preliminary estimate, a max acceleration of 500 mm/sec
