Re: [CAD_CAM_EDM_DRO] Re: Novice - Stepper Motor questions

Mariss,

I'd like to see it! I have several Minerta 50v servo motors that I've
seen used in daisy wheel printers. Also sold in Servo Systems
Catalogue. Funny shaft encoder on the ones out of printers. It should
do for the "brake". Don't know about the current sink.
