PINDA temperature calibration

My Z adjustment seems to be super inconsistent on the mk2.5 upgrade I just installed. I set it accurately, printed a great first layer test, then a couple minutes later when the printer had cooled down, I printed a first layer test that was absolutely smashed flat, almost with the nozzle crashing into the bed. It's as if the temperature is being way over-compensated, except that temperature compensation was off for those two prints (I assumed it was on by default, which is false), so that makes even less sense.

Anyway, I'm trying to run the probe temperature calibration now and it's been sitting on point 1 of 6 for maybe 30 minutes, and hasn't moved at all. Is it supposed to take so long?

Follow-up: my issue was that I'd plugged in the electronics wrong - I had the one-pin connector from the PINDA probe mixed up with the one-pin from the new hotend fan, so the PINDA temp reading was stuck at 25C. After swapping them back, my hotend fan no longer runs below 50C (it had been always-on), and I'm able to do a PINDA temp calibration.
