Failed print after few layers on SV08
Hi! I have had this printer for about 3 months and it's been mostly alright. Surely it is a bit fiddly but I can't complain about the size speed and especially the price. Some time ago I had plastic extruder gear tooth break and Sovol support sent a set of new ones together with extra spares I purchased. The printer worked fine for some time but one of the gears failed again and while replacing it I also changed nozzle to a hardened steel one.
And now I'm facing a very strange failure - the print is fine for a few layers but then it turns into a spaghetti mess. It is not a bed adhesion problem - it never detached from the bed and was properly stuck to it after I canceled the print. I tried two different petg fillaments that both printed fine before with the same settings. Turning off fans also didn't help.
I'm used to fixing my old ender 3 but I am very puzzled with this issue, can anyone help me figuring this out?
