RE: [CAD_CAM_EDM_DRO] power supply for stepper motors

This power supply should work fine for any of the Geckodrive drivers as
long as the voltage is apporpriate for your motors and the amperage is
sufficent. The resistors are likely there as current limiters for the
indexer which is likely not a chopper type unit. If you use the Gecko
G2XX drivers you will not need the power resistors.

I would be wary of using Gecko G3X0 servo drives with a plasma cutter.
It seems difficult enough to eliminate interference on the encoders on a
mill and it will only be worse with a plasma torch.
