Hello everyone, I’m looking for P2S owners who have experienced the same issue. My printer is approximately one year old, with only 420 printing hours, mainly using PLA. It has always been used for simple prints.
The problem:
-
The printer is printing normally.
-
Suddenly, it makes a noise, like abrupt braking or grinding.
-
The toolhead unexpectedly moves to the rear nozzle-cleaning station.
-
It cleans the nozzle, returns to the model and resumes printing.
During the print shown in my video, this happened FOUR times. On previous occasions, the printer also resumed printing in the wrong position. No error messages appear. I have already cleaned and lubricated the XY idler pulleys, checked the belts and toolhead movement, and completed a full calibration. Everything moves smoothly, but the problem persists. A ticket to the Bambu Support is open and it takes days.
The issue started on November 4, shortly after updating Bambu Studio to version 2.9.1.70. The printer firmware is updated.
Note about the video: I removed part of the audio because I was speaking very loudly out of frustration but you can hear the noise.

Has anyone experienced this exact sequence of events? Did you find the cause or a solution?
Thank you for your help!
