I am trying to adjust my post processor to have the machine go to the back left corner after the job is done using:

M5
G53 Z0
G0 X0 Y120

When this executes, after the Z moves to the top, as the machine is moving across to the XY position, the Z starts moving down. I can specify a Z like G0 X0 Y120 Z6, but I prefer not to guess what a good Z is here and just have the Z stay at Machine 0.
