@siam This fixed the issue, thank you.

@phaedrux The z probe value in duet web control is at 0 before trigerring, and remains at 1000 after triggering.

I have a Duet 2 Wifi with a Precision Piezo set up in digital mode. I had some initial trouble setting it up, but now the Z-Probe will trigger, but will never untrigger. The leds on the Zprobe still trigger correctly. Any thoughts on solutions? Config pasted below.
