I have an old (1998) cnc machine with fanuc o-mc control on it.
When i try to use multiple work coordonates, in this case G54, G55 and G56, and it gets to G55 it goes z overtravel.
If i run the same program with just one woork coordoante system (doesn't matter which one), it runs fine. Below you can see a part of the program. I use Fusion360 as CAM and the Fanuc post processor from fusion library, if that matters in any way. Bellow you can see the program i am trying to use.
Also the machine has an umbrela style atc, which if offset by one. the atc pocket 2 corresponds to T1 in the control, and so on. In the diagnostic screen T1 is assigned to D420, which is the tool in the spindle, D421 should be T1, but i do not know how to change this settings (diagnostic and parameters are two diffrent things on this machine).
Any help will be greatly appreciated
