Hi,
I have pored over my post processor, I cannot find where to modify it to do the following: end of cycle rise up all the way, go back 300mm.  Is this an easy mod, can it be done within Mach 4 apart from the post processor? I did attach the avid post processor.

Currently is makes this: "G0 Z15."  Id be happy with
"G0 Z80.
Y300"

Thanks

Is homing setup on your machine? If so, you need to set the position for G28. For instance - on mill mill I have G28 go yo Z Machine Home 0, Y machine home zero, and X -6.5 from machine home to put the table toward the front and centered.
