Thanks for the reply!
Cannot find manual on net
But the web site is   stepper3.com
drive is  stepper3 rev 0c    model stepper3 roc
manual says 1v above and 6-10 times the amps listed on stepper when using a common power supply
When i use these v and amps(7-8v 12a), ipm and velocity must be set low or i lose steps
When i used 12v i got better performance but motors were getting warm.
  Might be time for a better drive

Hi
First post here and have a question on selection of a power supply for my bench top mill.
I am using a 3amp stepper3 3 axis control  with 304oz 6v 2amp unipolar steppers.
Everything is wired and working,now my question is,  what voltage and amp power supply would
you guys recomend?
I have read in past post art saying 60% amperage of all three motors.I have used 12v 10a with ok results.
In stepper3 manual 24v seems to be the max.
This is my first cnc project and I am planning on buying another 3axis control board but for now trying to squeeze
a little more out of this one.
Thanks in advance!
