Z calibration
Hello,
Last night I did my first calibrations of the first layer.
I lowered Z to -550, but apparently I need to lower it further.
Question: Is there a safety feature that prevents the nozzle from hitting the plate when lowering?
No, you are calibrating the safety level.
If you are using the built-in first layer calibration routine then at the end of the calibration you are aiming to print a single layer postage stamp sized *sheet*. It should be possible to peel it off in one and fold it without the threads seperating. If it breaks into lines it is too high, not squished enough. If it is a single sheet but with wavy lines or drag marks on it you are too low.
If in doubt feel free to post a picture of the result of the calibration run *on the print sheet*.
Cheerio,

You can speed it up by using something like my calibration strip https://www.prusaprinters.org/prints/105404 to test a range of values in one run.

I had a problem like that too, I was printing something and it had weird squiggly lines on the first layer. The edge started peeling and the nozzle seemed to burn some of the filament on the edge. luckily I stopped the print before it got too bad, but the print was still ruined.
I tried recalibrating the level of the first layer by lowering it, but that just made it worse. apparently I had to calibrate it higher.

anyone care too guess what's going on here ....

at a guess I would say, there is a missing picture!

RE: Z calibration
Hi Joan .... not really I did the test with orange Prusament ... dried the white and decided to test it ... only thing I did in-between was to finally securely attached the Z axis brace .... amazon delivered the M5 screws and t-nuts .... here's the orange pla layer again ... then the white pla after afixing the brace ... I did snug the axis screws again and later this morning I'm going to Lowes to get a cement paver and I'll try the live Z test again .... thanks
