Title: backlash comp, pendant and mdi difference
Post by: jonny quest on May 28, 2012, 11:54:08 PM

I have .004" backlash in my z.

I tuned it out with backlash compensation, and was verifying it with my Vista CNC pendant.

I then decided to check it with an mdi command. It was spot on with pendant, but overtravels by a thou with mdi.

Why would this be?

I love it when I figure things out for myself!

When I entered z-.001, then z.001... That is actually .002" movement.

Everything works like it should.
