I just need to get pointed in the right direction -
I have a Bridgeport Series 2 with air assist on Z axis. If we turn the air off over night and forget to lock the knee the Z will wind up at the bottom of it's travel below the limit and homing switches.
So I want to have the homing routine look at the current position variable, add to it and make a small move to get it above the switches.
Thanks!
