Thanks Eddy

I had a look at a different gecko document to get the voltage and amps but thanks for the link, I will check that out.

I know not to daisy chain the drivers and will look into the wattages now but I thought the rule of thumb regarding the amount of amps provided by the power supply was 2/3 of the combined total of stepper motors.

The steppers I want to use will draw a current of 4.2 amps each, x3 = 12.6amps so 2/3 is 8.4amps, am I totally wrong with this?

Just looked at my post again, that was supposed to be 60v not w, whoops...

Thanks
