Re: [CAD_CAM_EDM_DRO] Repeatability of microswitches

Spehro,

Good question, I'm in the same place. The motors run, now it's time to
add limit switches and a HOME. I'm thinking about using a photo
interrupter, and AND the signal with a phase from the stepper. This
narrows the "width" of the home. Now, where to put them?
