That's all it was. I deleted both deploy and retract probe files from the SD and problem solved.
Thanks so much for that dc42. Because I was using the IR probe I never even looked at the deploy or retract so couldn't work out where the command to move outside of the soft limits was coming from and I never read anywhere in the G30 or G28 codes about deploying or retracting.
Thanks mate

RE: Z-probe command (G30) causes runaway in X and Y
I changed the offset when I was mucking about trying to find out what was going on.
I've changed it back to what it should be.The problem is when I issue a G30 command my understanding was the bed would come up and trigger the probe at the current X and Y position. Is this not the case?

Z-probe command (G30) causes runaway in X and Y
I've just set up my coreXY and can home both X and Y axis but cannot for the life of me work out how to probe the Z.
The homing endstops are at the positive end of travel for both the X and Y and they home no problem but when I hit home Z the printer runs very slowly diagonally back to X/Y zero then probes the bed, the probe triggers and causes the bed to drop to its maximum and then for no apparent reason the head takes off in an X negative and Y positive diagonal until the carriage crashes.
I initially se it up with reprap configurator and have had this problem from the start.
Thankyou
