I have a job that I am having problems with after moving to the EX controller. I make a small box that uses G54 and G55 in the gcode. The box and the lid are machined from their own stock and set to G54 and G55 respectively. I use multiple tools in the job so one tool will do both offsets before I change tools. when I was using mach4 I could see the G54/55 commands in the gcode when it should switch between offsets, however the since using the Avid CNC EX Router post processor in fusion I dont see them… Does anyone know how I can get fusion to generate them in the gcode? are they even needed with centroid or does it use a different command to switch between offsets?

They are turned off by default in Fusion

You can turn them back on:

No problem!

And just to add, switching WCS systems in G code is super easy:

G54, G55, etc are all you need to switch them. You can also do it manually in MDI by entering those commands, or you can go to Set Part Zeros\>WCS Table
