Calibration problems

I just made the latest slicer/firmware updates.

And so, i did the complete calibration.

flow dynamic done.
flow rate…well see:

What is happening there?

Looks like a local bed adhesion problem. Maybe a couple of fingerprints?

Once that is eliminated, you may also want to heat soak the print bed a little before the next calibration attempt or even uncrease 1st layer bed temp by 5°.

Seems to be not calibration only:

Ouch.

Is the filament dry? It looks way out. Keep in mind that new filament is usually moist and will print worse.

Next, is that with a 0.2 or a 0.4mm nozzle?

With what filament (Brand & Type) and which temps (in particular nozzle) are you using?

Finally, you can try printing two figurines in parallel but separated by a distance on the build plate or enforce a prime tower by taking a smooth Timelapse. Both will increase layer times and force the nozzle away from the prints to enable sufficient cool down of each layer.

0.4
maybe moist
Bambu PLS refill

Printer also somnetime comes up with “Partcoller not working” yadda yadda

That is rather important! Check if the part fan is working. If it is not, you’ll not get a good print.

If the part fan is not working, the filament takes too long to cool and become firm, so the model moves around with the nozzle, as shown in your gif.

Definitely check your fans. It looks like your filament isn’t drying so it just wobbles around and gets bad adhesion.

Never thought of that! The partcooler is dead.

dead dead.

Seeing that you are based in NRW, open a ticket with Bambu and ask for a part cooling fan replacement under warranty (if that still applies). It may take a bit of back-and-forth, but with a broken part cooling fan the machine is not gonna give you acceptable prints.
