nozzle / pinda calibration
I got my MK3 kit, built it and calibrated it without any special problems.
I successfully printed something like 10 or 15 prints
and then had my first failed print.
I am now trying to re-calibrate it and when I get to the first layer calibration I can see that the nozzle is so high above the printer that it just drops the filament onto it (i.e. its too high).
I am a bit confused on the order of doing things.
The PINDA adjustment part of the kit assembly is shown to be performed without the steel sheet and the the "Calibrate Z" requires that the printer be without the steel sheet on?
It seems like aligning based on the zip tie height does not work that well (it positions the nozzle too high and live-z only seems to allow me to adjust z upwards...
1) what does the PINDA sensor (by the way - what does PINDA stand for?) sense ? the bed or the steel sheet?
2) what should be the height of the nozzle above the bed when adjusting the pinda? 3) and what height should the pinda be above the nozzle ?
4) why does Z adjustment not let me move the nozzle downwards to make the printed material more "squished" as explained in page 24 of the manual?
also I wanted to say that when Z calibration starts it first moves on X and Y and if the nozzle is touching the bed it might damage the bed and it might be smarter to first move up on Z before moving horizontall.
Is this a good question?
