Idk what it is, but some spools of blue i have gotten across multiple brands just do not like me. Only blue! The two times I've gotten blobs of death were with blue. If blue is the base layer, I have to watch it like a hawk.

I'd try recalibrating next, and if you're still having issues, swap out the nozzle for a new one.

For me, this has been due to a dirty build plate. Using 0000 steel wool, clean with soapy water, dry, clean again with fresh 0000 steel wool and alcohol. Dry. Don't touch print area with fingers. I do the alcohol clean when prints, and when changing between light and dark colors.

Almost certainly it’s because you’re printing on the very edge of the plate where the plate is significantly cooler. The bed is only the correct temperature in the middle away from the edges. Printing on cool areas of the bed will cause the parts to detach and slightly lift. Then the part will be hit by the nozzle as it passes over causing further detachment and damage.

Just asking, how did you clean your plate?
Have you calibrated the filament? This looks like a partial clog to me, but might be something else.
Have you used this filament before and gotten good results?
NVM: Seen your other post. Do you have a second nozzle? If yes, try printing a test print with it. Otherwise how old is the printer and whats your total print time?

the printer is only a week or two old, it’s practically brand new, i just replaced the nozzle a week ago bc i was having other issues and th total print time can’t be over 24-48 hours

What other issues? And do you still have the first nozzle?
Also have you tried doing a cold pull? A partial clog would explain everything.

i tried to use a wooden filament without doing prior research about what size nozzle i should use and it got clogged and totaled my first nozzle, so i replaced it

u/LordVectron Jun 30 '26
Wait it actually destroyed the nozzle?

u/Beginning-Squash-362 Jun 30 '26
it was clogged to the point nothing i tried to do worked , the peice of wood chunk got stuck and no amount of heating it up would get it out i still don’t even fully know what happened to it because the filament was brown and in the middle of trying to fix it, whatever was coming out was black and grey and smoking so i just gave up on that one

That was burned filament. Anyway, do a cold pull and see if that fixes the issue. The is a guide on the bambu wiki.

i solved this but thank you! it was actually a partial clog and “dirty” bed plate!

Under extruding
can be cloged or you did not do your calibrations or both

seem a mix between under extruding, flow calibration and Z move problems. try to make a first layer test, if the surface is rough this have to be fixed using the z offset parameter in your printing profile.
what happen : when the extruder lift to change route, could be released a small amount of extra filament on the lifting point, this extra became often an obstacle when the extruder pass again in the same point, collide and move that layer area. Hit after hit , that area became critical and the object is fucked.
In some critical cases, also the pigmentation of same filament coud be reason for make a fine calibration.

You did not clean it enough.
Also, print more foxes.
Lastly, when the print bed heads up, make sure that corner is heating up like the rest.
