Describe your issue:

Hello,
my printer cannot home Z-axis via G28 anymore after updating to version v0.12.0-256-g6d700502. I had no issues before.The X- and Y-axis perform homing, Z-Axis moves up and goes to the middle of the bed and does not deploy the probe pin anymore. In the console I can read:

BLTouch failed to verify sensor state; retrying.

BLTouch failed to verify sensor state; retrying.

BLTouch failed to verify sensor state

My debug: pin_up and pin_down, both work. QUERY_PROBE gives me “probe: open” and when touch_mode is enabled, it reports “probe: triggered” when I touch the probe pin. Also checked the wiring, everything fine. As I said before, the printer performed well before the update. I saw on GitHub, that bltouch.py was modified 5 days ago. Maybe the reason is here?

Same here. Genuine v3.1 BLtouch. Tested another with same result. Tested against a spare MCU and same result. Host v0.12.0-258-g9318901f MCU v0.12.0-257-g4d21ffc1
