Regarding wet filament:
I ordered some other brand, brand new bag, printed and had all kind of print issues (layers separating, filament clogging nozzle, uneven layers, even tested extruding filament and saw bubbles appearing). Sometimes it was ok, but mostly had failures.
I really had no clue what was going on untill I tried to dry filament.
I used my microwave oven (but in convenction mode) and set it to 50C. Used old kitchen rag and wrap PLA spool in that. Considering I can only set to 1hour timer, i did that for at least 5-6 times. No more print quality issues.
So you can try this method to dehumidfy your filament and i would advise to use rag like i did, so that the spool is not directly exposed on oven heater. And yea, different fillaments require different temperatures (PLA is safe with 50C, PETG needs higher I think, ABS also higher…) so take that into considering.
The 1st time I cleaned my LIDAR, I kept getting that message too. Turned out I had not seen the diodes as it is tricky to get a good view there. Check the wiki for that. Once cleaned with IPA and a Q-tip, it went away with the next self-test.
Calibration in Bambu Studio is straightforward. Just go to the Calibration and run through the steps. Just don’t confirm a succesful calibration print in the printer before saving it through BS.
Further options are in Orca slicer but BS aleready covers a lot of ground.
I had a similar problem and it was not wet filament. PETG is extremely sticky, and it sticks to, and builds up on, the nozzle. When enough of it builds up, a lump can fall off and end up on your print and get dragged around. So first thing, I’d watch your nozzle closely while printing and see if that’s what happening.
When I noticed this, I started doing some test prints. A temperature tower indicated that the print head temperature should be higher than I was using. When I print PETG around 275-280C, it works great! Yes, I know that’s higher than the recommended temperature range for PETG, but it seemed to work well for me. At a higher temperature, the PETG is more fluid and doesn’t stick to the nozzle nearly as much. I also needed to turn the part cooling way down, and turn up the chamber cooling.
I find printing my Orange EYRONE PETG at these high temperatures also works really well!
Thanks for all the replies. I cleaned my lidar sensor better and i didn’t get the warning anymore. I also printed the hygrometer bins and inserted silica-gel. So far the prints are good again
