RE: [CAD_CAM_EDM_DRO] Driver current in steppers

Very interesting! I will have to remember that. A very similar setup is
used on my old WWII vintage Lionel Train Transformer.

Hi Bill and the List,

For an experiment, I connected a 12V auto (US) brake light in series
with the 45V motor power supply to my new/used Centent, er, Gecko
microstep driver. This doesn't appear to affect the motor's operation
at all! You can thus watch the current drawn by the driver, and it
affords some protection in case of a wiring short. 2A current set, 350
oz/in 3.43V, 3.3A NEMA #23 SloSyn stepper (yes, I'm only running 2A).
