Z-Height Calibration Offset / Adjustment

I’ve run the bed leveling and z-height check multiple times.

The first layer of my print is always squished. Everything is telling me to set the z=0 height via offset, but the only way I’ve found to do that is via this thread : Finer adjustments to z offset?

Is there a better way to do this? I’m hoping this will also work for this IDEX machine, since that’s for an Artisan machine.

My local testing of the G1029 D x.xx command from the terminal yielded no change in the z calibration and resultant first layer.

I am having the same problem, but with a hovering nozzle that doesn’t come close to the bed.

Tried to manual raise to ‘0’, but it stopped about 10mm away from the glass bed. Tried a ‘turn a bit higher’ on the back knob, then ran heat bed leveling again. After trying a calibration print it was a ‘tad’ closer but not enough.

Tried another guess adjust height and ran heat bed leveling again. Ran the calibration print and the back was smashed and other corners of different heights.

Have to agree, is there a better way to adjust Z? I feel like I’m guessing to get there with a lot more steps than any other printer.

I dunno what M1029 is exactly, but I use M206
eg it may look like this by default:
M206 X0.00 Y0.00 Z-13.38
Moving it more towards Z=0 will be closer to the bed (eg in the example above, changing it to Z-13.33 would be 0.05mm closer to the bed), more away from 0 will be further from the bed.
Doing a print bed calibration will erase this value, but once you have done it a couple of times you will typically know by how much you want to adjust this value, so I find it pretty quick.
