Ok so you have your native units set wrong, you have them set to inch and you should have it to mm. Config menu then Set Native Units and change to mm. Because you already have the motor tuning set to correspond to mm then it is likely you will not have to retune the motors but go carefully just in case it screws up.

OK there is the 4.5 " offset in the g54. That was why I asked in the beginning about fixture offsets. I  Bet you have mach set to cancel all offsets on a M30 (;-) if so when the M30 ends the program it removed the 4.5" of fixture offset.

That could be part of the problem.

Still a little weird about the switch when it converts over to G21. It does it here as well, BUT if you rezero after it does it it does no harm. But IF you don't rezero it will go to another location.

Just a thought, (;-) TP

I reconfiged. the menu and changed to mm.  I removed the offset and zeroed all .  Program runs as it should.

Thanks to all for all the help.
