My machine has the X008.7 SKIP1 input on the same pin as Single Block mode (SBK.S), so if I try to use G31, it works correctly, but then I have to hit the start cycle to have the machine continue again.

Parameter 0017.4 is already zero (tried 1 just to see what would happen).

I also tried the X008.4 (SKIP4) input and set parameter 0033.3 to map SKIP4 to G31 P1, without success (the input was working according to the diagnostics screen).

Machine: Fanuc 0-MD without PMC

Is there anything else to try? I haven't tracked down where this is configured in the ladder logic - if I do, is there a chance I could change it or is changing the ladder going to be a nightmare?

Thanks,
Eric
