Live Z - First layer CAL, cannot go Postivie ?
Hi ALL
My printer went stupid so I've reset the calibrations (XYZ) and used the wizard again.. The Z is too high and I want to change the live Z to get closer. I can rotate the wheel to get a - (minus number) however I cannot go past 00:00 and get a positive number (to get closer). This must have changed in a firmware release ? I need to get the nozzle closer using Live Z, any idea ?
Thankyou
RE: Live Z - First layer CAL, cannot go Postivie ?
negative means closer. 00.00 is "all the way up". Normal range is -1.00 to -1.8 if you installed your PINDA according to the instructions.
If at first you don't succeed, skydiving is not for you.

Just chatting to support and they said the same thing, oops 🙂 I swear the older firmware had it the other way around !!! Anyway, all good... thankyou !!!
RE:
You'll need to move the PINDA lower
The Super PINDA should have about 1.5 mm distance between nozzle and sensor, so that you’re around -1 when your Live Z is correct. That gives you enough wiggle room up and down.
Instructions for adjusting the PINDA are in:

I put this little helper on Printables to help position the PINDA: https://www.printables.com/model/57192
Works better than zip ties or credit cards, which have less well-defined heights.
