Re: [CAD_CAM_EDM_DRO] Re: CNC Converting Questions

Thank you all for your help.

Another question, what is the determining factor in deciding which
wiring method to use, full or half? Any advantage other than power
supply requirements?

If a motor is rated with a step angle full/half will micro stepping be
possible with a driver like the Gecko? I am a little confused:(

Anybody had any experience with ClickAutomation steppers or would care
to recommend another distributer?

Thanks again for you input.
