hi. tnx for the reply!!

its nterpretation 2: everything simple quits with no more interaction until you reset the printer.

I've done quite a lot of different experiments and the problem still exists

i print pla. I tried different temperatures - 200c/205c/210c/220c/230c
I was suggested to try different retraction settings. I tried 6.5mm-25mm/s(cura default)/3mm-35mm/s and 1.5mm-30mm/s

Until now, nothing has solved the problem

I wish you could guide me how to get through it ..
