Probe Active before non-probe move

      Hi all;I was having this error randomly pop-up while running my level-check routine. Searching the forum I found  Billiiles  response to seuchato's post on a similar topic and applied his suggestion to add some dwell to insure the machine was stable before the next move statement, but I'm still getting random errors during the routine. The routine I wrote uses a touch plate made from 1/8 aluminum plate offset from the table by 5 cabinet bumpers, one in each corner and one in the middle. (See attached picture).I had used this routine and plate extensively without issues prior to a major rebuild of my machine to add a second Y axis to eliminate racking and a 2 DOF gimble to square the Z axis to the table. With all of that retrofitting completed over the winter I'm finally back to leveling the table. Now I'm having issues with the routine. In addition, I've verified that there is a open between the plate and the table using an Ohm meter on the 2 ohm setting while there is .2-.3 ohms resistance between the touch plate and the point where the touch plate cable plugs into its receptacle on the front of the bench.  Connection is made with a banana plug and socket. I've attached my code for your review. I'm probably missing something obvious (forest and the trees syndrome).  Any suggestions would be greatly appreciated.

Kind Regards,

IMO this is a bug in the source code, i have this error disabled in the codebase I use for work

I once set a digital input in my probing sequence that was and2'd to the probe signal to stop this.
I think a better way would be to use motion.motion-type = 5 to signify probing was in use and disable the signal if this is false.

I'm currently running 2.9.4. BTW- the error always occurs at line 38, G0 Z0.
