I don't understand this Z-Live calibration

Hello everyone,,

I ran through all of the calibrations and everything was good except the nozzle was rubbing the bed on location 2 (it rubbed some of the printed white text off of the bed). The machine still printed and I had the Z-Live set to -0.560. Tech support said I needed to drop the PINDA and run the calibration again, just make sure I didn't drop it too far. So I lowered it ever so slightly, reran the calibrations and no rubbing this time. Now the Z-Live setting for the first layer calibration is at -0.900 and the first layer looks bad, it still needs to go lower. I thought if the PINDA was lowered the Z-Live would get smaller not higher. I don't know what to do now. Any suggestions?

Thanks.

First off, set the PINDA level like the construction manual shows. Drop the nozzle to a sheet of paper on the bed.

Loosen the PINDA and slip a piece of zip tie under it. Use that as the spacing. Tighten the PINDA mount - and don't change it.

Now read this and follow:

Closer you get to the bed, the more negative Z gets. Not smaller - more negative. Don't let the nozzle - ever - touch the bed.

It will no neither the nozzle or the bed any good.
