Don't get hung up on the rule of thumb about using 10 - 25 x the voltage to
drive steppers. It is true that you can get faster rapid moves with higher
voltage if you are using current limiting drives, but you can also drive the
motors at lower voltages and get fine performance. My first CNC set-up was
with a Camtronics 5 amp chopper drive kit running at 24 vdc. It gave me 90
ipm on that machine. Yes I could likely have gotten 120 ipm if I used 60 vdc
and drives that could handle the voltage, but so what. 90 ipm was more than
enough.

Hi All:

I'm looking for a Circuit, or Kit for Bi-Polar Steppers. Except for Gecko,
I've only seen ones using 24 volts or less. It's my understanding that I
should be running my Steppers up to 20 times their Labelled Voltage but at
the Labelled Amperage. My Steppers are 6V and I would like to get up to 60V
minimum.

Thanks

John Bell
