why would you upload to tiktok!?
Maybe something is loose, like the tube that the filament travels through? It definitely seems to be clicking during retractions, but if the print quality isn't affected then it's probably not the stepper motor or extruder.
I don’t have a BambuLab printer, but the printers I have owned have done that when the nozzle is clogged, when over extruding or when the print bed is too close to the nozzle.
Basically, something is preventing the plastic from extruding out and the extruder motor is slipping.
After watching the video I’m not certain what it could be, but I’ve heard similar before from my printer so I’ll list them in order of sound similarity:
- My X belt wasn’t fully aligned in its track and it was rubbing on the side, which caused a similar clicked noise when any X move occurred.
- When there too much pressure in the hot end (from a clog, low temp, or too close to the bed, etc), I’ve seen the filament “kicking back” out of the extruder. Watch for a sudden backwards jerk of the filament.
- My X stepper motor made some terrible noises after tightening the associated belt. I’m not sure what’s causing it exactly, but I’m replacing the stepper soon.
