I'm trying to configure an infrared probe from filastruder and I'm having some issues. I normally use proximity probes that are detachable and below the hot end. This seems to work great and I have no problem with auto calibration.
I'm not sure if it's related, but this probe is above the hot end and it will not move all the way down to the bed using G30. It stops at varying spots and reports like it received a probe hit.
During full calibration the first probe doesn't match the second so it stops.
Do I need negative probe heights? Or am I just getting false readings from the probe.
Smoothieboard v1,1, output pin connected to GPIO pin 2.11. Probe registers when manually triggered checked using m119
