I'm having issues with a new to me Excel PMC5v20T. I believe the tool macros are not present. Does anyone have a copy of the original macros or even suggestions on how to write new ones. The front panel controls will rotate the pots, and move the pot out/in but tool arm isn't working. Should I see the programs in the program list or are they hidden? The machine has a Fanuc 0-m. I do have a parameter backup but no tool change macros are saved if there are any.
