UGS touchplate error

I get this error using Dec, 2020 UGS whenever the touchplate is triggered. Any thoughts?

Error: An error was detected while sending 'G38.2 Z-20 F100': (ALARM:4) 
Probe fail. Probe is not in the expected initial state before starting probe cycle when G38.2 and G38.3 is not triggered and G38.4 and G38.5 is triggered. Streaming has been paused.

@jgroppe Welcome to the group, John. What axes are you trying to zero - all of them, just Z, etc? Can you post screen caps of your touch plate settings?

Our original problem was a wiring error. We fixed that and tested continuity. To protect denting the touch plate again we were manually completing the connection. This is when we got the error. We switched to using gSender, and got an error doing the manual connection. But allowing the machine to do the probe, everything works! My hypothesis is that the probe program retracts the bit, and we couldn’t do that fast enough manually hence the error.
