Z Adjust Positive Broken
Since the latest firmware update (3.12.2), the z height adjustment (both first layer calibration and live adjust) can no longer be adjusted in the positive direction. My smooth sheet cal should be 0.6, but it's stuck at 0 (or negative), which is unusable for me. BTW, the wheel works fine for all other operations.
I'm dead in the water. Please confirm that this is a firmware problem and advise.
Best Answer by JimB:
That Z adjustment should be between 0 and -2 (and -0.5 to -1.5 is probably a better target range). You might need to adjust the height of the (super)pinda.

It used to accept a positive number by moving the wheel clockwise.

I could be wrong, but I'm not sure you can set positive values. You would normally be expecting the Z-offset for the first layer calibration to be a negative value assuming that you have correctly set the height of the PINDA probe. Mine is -1.4 or so.
Check the PINDA is not loose in its mounting and that the height is correctly set according to the build instructions on pages 130-131 or this web page.

Thanks Tim & Jim. I moved the super pinda down closer to the plate as instructed. Now I have a negative z offset and I'm back up and printing.

Excellent! Try a first layer calibration by printing this test strip. You are aiming for a smooth top surface with no visible gaps between the extrusion lines. When it comes off the bed you should not be able to easily pull it apart. Also hold it up to a light to see where there are holes.
