[BUG] MicroProbe doesn't stay down with "BLTOUCH_DEBUG COMMAND=pin_down" #772

Closed YosypC closed 1 week ago

YosypC commented 1 week ago

Either BLTOUCH_DEBUG COMMAND=pin_down or BLTOUCH_DEBUG COMMAND=pin_up result in the probe deploying and retracting without any further command. Homing and further debugging will fail.

BLTOUCH_DEBUG COMMAND=touch_mode will deploy and retract. QUERY_PROBE will yield TRIGGERED with !PC14 and OPEN with PC14 and ^PC14, both when the probe is still retracted.

edit: the probe tests fine, with a couple of retractions and deployments when powered. the light always stays on.
