I have progressed calibrating my x and y axes using the encoders and without encoders the Z axis is also working, but the encoder is showing strange behaviour.
When i try to move the FB using manual mode in the webapp the encoder values jump all over the place and are generally quite low (100 mm movement show raw value variance of 40-60). Manually without encoders the motor will perform the movement just fine, but the moment i turn the encoders on, I can hear and see the software struggling with retries and the movement is not completed.
What is even more strange that at the moment I disconnect power from the z axis motor and move the lead screw by hand, the encoder values is changing and showing more consistent behavior.
I have set the A4988 stepper driver to 4 microsteps
I have tried various settings, have checked the cable and have reflashed the FB but no success. Any ideas anyone?
