Ive recently purchased this old machine (1987), I had to restore all the parameters, im missing the 9000 programs- but I dont know if that affects this problem:
I can home all axis, I can move them all, orient and run the spindle in MPG/INC modes.
I cannot get the AUTO/MDI modes to run any code.
The cycle-start button does return the right switches in the diagnostics, so physically working. Its like the PMC isnt communicating with the CNC to actually run code.
I cant for the life of me figure out the ladder (printed with near invisible ink in the manual) to find out of im missing anything.

I don't know fanuc ladders at all, but im learning- searched through every site and post i could find. Most posts just die out without posting results.

Any help would be greatly appreciated!!
