Bad adhesion on a new plastic

Hello, newbie here.
I’ve printed an object using Bambu filament - everything went fine. Now I’m trying to use another filament, PLA too but another manufacturer.
Temperature recommended by the manufacturer: nozzle 210-230, bed 50-70. Two attempts - the object pops up from the bed at random layer, therefore spaghetti.

The printer is new, it is the third object in its life only, so the bed (Textured PEI) is clean. The filament is dry (I believe), and the humidity in AMS is 35%. The settings are on the screenshot. It is P1S, so the printer body is closed (doors too), so the air temperature is stable.

Could you please help - how to fix the issue? Thank you.



A new printer does not mean the bed is clean.

Wash the bed with dish soap and hot water, dry it with a new paper towel and be sure not to touch the surface.

Maybe need to calibrate your new filament, they won’t be the same as the Bambu settings.

@JonRaymond as a laugh Bambu Labs should stick a Dawn Sample sachet to the Build Plate. Every Dishwasher and Washing Machine come with samples. Heck, maybe they need to make their own formula like they do with Gluesticks.

I know that we must not touch the bed, and I didn’t. I’ll try to wash it, though, thank you.

calibrate your new filament - yes, but how? Any instructions for newbie?

Its under the Calibration Tab. Here on the Wiki is probably a good reference (for a lot more than this too). I’d recommend the Automatic methods.

Just a heads up, the P series only has the manual method available.

Just try using the generic profile to start with for new manufacturers filament. Don’t pay much attention to the minimum temp settings on the box, your printer will usually need higher temps than recommended, due to the faster speeds it’s capable of. If it says 230 max, print at 230.
And like others have said, if it’s coming off the bed, is likely an adhesion issue. Or it could be your nozzle is hitting the infill, which appears to be quite common when using grid infill. Gyroid is better in this regard.

Solution: I’ve increased bed temp from 70/60 to 80/70, and reduced min fan speed to 10%.
Also, I added a brim of 3mm, but it was unnecessary: with the brim, the adhesion was so strong that it was difficult to get the object from the plate.

No washing was needed.
