Hello,
Having a strange issue with my BlTouch on my smoothieboard. My probe is behaving as follows.
When it starts up, the probe end closes, extends, and then closes like normal.
The red light is on the probe while the prob is retracted.
The probe extends on M280 S3.0
The probe retracts on M280 S7.0
M119 Always results in saying that the probe is triggered. When I attempt to start a print (with the probe up), it fails and says that print aborted due to the probe already being triggered. (My start g-code is with an auto leveling sequence).
What could cause this behavior? Has anyone else experienced this? I also included my config for endstops/probing.
