Axis registers not Zero-ing when homed was created by jamby
Hey
I am just finishing up after installing 2.8 and I noticed that when homed none of the axis registers are zeroing out. Which is what I remember was normal in 2.7. Or am I just suffering another brain fart?
Thanks
Jim

You have some offsets in place...

Once again the brain thingy gets me. I have a program named Zero that clears all the offsets.
You don't have a write up on how to set up the homing function for a 3 axis bridgeport mill do you?
Thanks again
