Kitchen table tip from Mariss - a "safe" power supply
 

Mariss (the designer of the Gecko drives) says that if you use a 24VDC 1A power supply while you are testing, you CANNOT blow anything up! I know the V series are supposed to be un-killable, but...seems like a great tip. Most old printers in my house have a 24VDC 1A supply.

Bench-running means putting it on a desktop, wiring a motor to it, connecting a step and direction source (if Mach3, then in 'ports and pins' set STEP 'active high, in 'motor tuning' set step pulse width to 2 microseconds).

Find a 24VDC, 1A power supply. This is a little known secret; you cannot blow up a drive with such a supply no matter how badly you mess up motor or supply wiring. Get the drive to spin a motor with this setup. Once it does, move the whole shebang to your machine and use a more serious power supply (50VDC). Things should go smoothly then.
