Not an issue, but an idea about autocalibrating switch_offset value about klipper_z_calibration HOT 4 CLOSED

I was just thinking the same thing, but a step further: if we probe the two end stops right on top of each other as you describe, then we don't need to probe the body of the mag probe at all. Thoughts?

I'm sorry, this will not work! Please read the switch section. I had this discussion already many times!
How would this solve your intention to measure or eliminate the switch offset? Can you tell what exactly would happen if you do so? I cannot.. it depends on so many things and even if it does what you think it would be very fragile. It would just work out in a perfect world where both switches always trigger at the exact same time..

I had the same idea, but just because the Z Endstop's switch triggers, doesn't mean that it doesn't travel further down after being triggered - potentially falsifying the actual travel distance. Same for the magprobe. Depends on who triggers easier.

This would (maybe) work if both switch trigger and have 0 travel of the switch actuator afterwards... or not, i need to read up on that again. ;-)

Correct! And, even if there would be no overtravel, the probe has to trigger before the endstop - reliably! The latter one could be achieved by a sexbolt endstop with a spring...
