[Solved] Z Axis Calibration Fail
If I lower the PINDA sensor, during the calibration process the Z axis lowers the extruder head and the calibration process stops and you get a calibration failed message. Sensor about 1.5mm off paper. Just noticed that the extruder is hard on the bed, guessing a bed sensor has triggered the failure.
If you lift the PINDA sensor as per 18.104.22.168, the extruder will start trying to calibrate, i noticed that the bed is being deflected.
The PINDA light is on, but how do you tell whether a signal is coming back from the PINDA to the motherboard.
just letting you know i had flashed firmware for Mk3S instead of Mk3. After reflashing with correct product firmware, z calibration was fixed.
FYI the PINDA light goes out when it senses the steel sheet. LED on = pinda off, LED off = PINDA on / triggered
