RE: [CAD_CAM_EDM_DRO] Wire Gauge for Stepper Motors

Hi Jan,

Thanks. I think I will use some 20 AWG wire I found. I only have three
different colors, but I managed to put a black stripe on one using a
permanent black ink pen, so now I have four!

I forgot about the ARRL Handbook. I'm a ham myself (AC6RN) and often forget
some of the generally useful information in there.

Thanks,
Kory
