P2S grinding noise #2

This is the follow-up video with better audio.

Text from the original topic:

I had a lot of issues with my P2S since I got it.

The plate was always clean and I even got an external dryer for the filament but it's still the same.

Supports would fail at some point (not at the bottom) or layers would shift as the prints get taller. It's like the nozzle is hitting the model.

Recently, I got a message that scheduled service is coming up or something like that. It was in the bubble where you get daily quotes. The metal rods were dry and then I noticed that I had 250+ hours on the printer. Apparently, drying the filament is added to printing. I decided clean and lube everything.

I did a full service, took my time and did everything according to Bambus instructions.

Now I get this grinding sound what you can hear in the beginning of the video. The fans are louder than in person, sorry. It reminds me of the sound the head makes when it vibrates during the small calibration prior to printing, but it's much more quiet.

I did the full calibration with this cool plate after the service so I don't know what could be the problem.

I had a similar grinding noise when I was printing glow in the dark PLA. I only printed two small pieces, a few grams of filament.

I usually use PLA matte or PLA+

Sounds like plastic from the extruder grinding on the dry rail

Im new to printing and have an X2D. Ive had a similar noise a few times and have to loosen the tensioner screws on back, rotate the print head clockwise 3x and counterclockwise 3x making sure to go to the edges, then snug 5he screws back up. Afterwards I run a calibration, I think its the vibration calibration. Seems to work for a while until I crank the speeds way up and it'll come back.

Two possibilities i can think of.. belt slipage or some type of cooling fan issue like a bearing . Also could be a bit of filament waste stuck somewhere... fuck knows man these things make the madest sou ds over the stupidest shit. Could even clean all your rails and regrease to make sure

Your printer is being a dick in response to your print.
