Re: [CAD_CAM_EDM_DRO] Re: Fred, Digitizing probe ??

Fred, I must not understand digitizing or have a misconception on how it is performed. My understanding is, that a pattern is ran with the X axis perhaps, back and forth, +/- with a stepover on each pass. When the stylus is traveling along and a vertical surface is encountered that is higher (Z+) than the present surface. What moves the probe up to the higher surface? Or use a round stylus with a radius greater then the height of the vertical surface? I can see dropping off the vertical to a lower surface but, not the other way around.

The probe stylus has to be longer than the vertical rise of any square
shoulder. If the probe body hits the shoulder, crash boom. It's not a
good thing.
