Z offset calibration

[jeffbearer]

Is your feature request related to a problem? Please describe. It would be a real timesaver that if before the bed leveling calibration there was one to determine the appropriate z offset.

Describe the solution you'd like Imagine a calibration that creates several tabs like the bed level ones but each one is set to a slightly different height simulating z offset. This would allow you to run one calibration and have 5 or so tabs with some small z offset change.

Describe how it would work Calibration menu like the others. generate buttons with useful presets, perhaps one coarse and one fine.

Describe alternatives you've considered I've considered that this can't be generalized to work in most cases. and it might cause out of of bounds violations in firmwares etc. idk what do you think?

I think it can scratch/destroy the bed easily, or be useless as they are all too far away.

You want another option in the bed level to be quicker to print?

Gotcha, in my case the paper test is too close. and I need to back off. And I've found using 1 of the tabs and adjusting the z offset in klipper lets me dial it in really well. but for example today it took 8 tries to dial it in after I did some work on the printer. So maybe it could be after the bed level test. ie . If your prints look like any of the too close. try this z offset test which will try 5 tabs with increasingly raised z that you can set the z offset?

I can add a button to generate a test with only one path at the center, for printer that can only be adjusted via a single z-offset? It 's safer to go down from a safe height without going into the "too low"
