Those lines appear randomly on a print. I print a lot of those frogs, some print perfect, some has this problem. What can be the reason? I don’t change settings between prints. And I don’t touch the printer while it prints.
Printer - P1S, Sunlu filament, latest Bambu Studio.
You could have some wet filament. Have you ever dried this filament?
filament calibrated and dried?
I dry the spools in AMS PRO, then start printing frog after frog.Wet filament just couses some stringing. Calibrated? No, but I print frog after frog from the same spools, and some are good, some looks like that.
This is not layer shift, but extrusion problem. Could be partial nozzle clog, failed bearing at extruder gear, worn out PTFE tube or simply dodgy filament that doesn’t have consistent diameter 1.75mm like some small sections have diameter of 1.50mm for example.
