I recently bought 2 rolls of Bambu Basic PLA in black and both rolls are a spaghetti nightmare. I also bought white and it prints fine. I dried one of the rolls and it printed ok but still not as well as the white. Any one else have this issue recently or is it just me screwing something up?
I just ordered the X1 with a bunch of filaments and AMS, one of those being black pla basic. When It shows up i’ll let you know how the black prints if someone else doesnt reply already.
I would really need to see a picture of what you’re experiencing. I don’t have any recent rolls of PLA from them, but the ones I have used in the pas worked fine.
I have already cleared the mess. I am drying the roll again and will try printing again later. It seems to print fine with any other PLA roll from Bambu. Will test and if it fails I will post a picture. Thanks!
I am printing with a random black roll now. I did flow calibration on every roll i put in to far and saved the config. and my prints are solid stuck to the plate and printing great. Ive run 4 different brands and no issues at all.
My poop chute is printinv right now and is 8 hours in with black pla and its looking very consistent. Ever figure yours out?
Thanks for the input. I dried the filament for 48 hours at 50c in a filament dryer and it seemed to be ok for a couple small prints. I dried it previously in the X1C for 12 hours but it didn’t change anything so I dried it even more. I have not tried a larger print yet but maybe 12 hours wasn’t enough. I will try some larger prints to make sure it continues to stick. I can’t believe the first drying wasn’t enough but it seems like that may be the culprit
Possible, Did you leave the filament dryer cracked open at all? Mine tends to bring the relative humidity up to about 50-60% on rolls that have sat for a month or two If i just shut the lid and leave it. If I don’t crack it open (if its the sunlu dryer like mine then you have to open the lid a crack and slowly let it down so it doesn’t seal) and let it run while letting out all the “wet” air then the RH meter stays at and raises slowly basically baking you filament in 60% air. when I crack it open for about 12-16 hours it brings it to <20%. I test this by securing the lid fully shut and leaving it for an hour to see if the RH% goes up at all. If it stays at 20-25% I consider it dry enough otherwise i crack the lid again and let it run another 6 hours.
If you already do this then good.
Other than that every single one of my random rolls no matter the color have all printed virtually perfect as far at prints go (Aside when i did a low surface contact PETG…that spaghettied all over, User error) including mixing up different brands and SIlk/basic/matte/CF PLA all in one print. SO definitely validate its dry and and retry, then go from there.
I’m loving the printer so far and my kid loves it more than me with all the “new toys” in multi-color she gets almost every day.
So quick update. I replaced the nozzle and it seems to help. I still get an occasional problem with adhesion but as long as I watch the flow control and verify it is sitting well the rest of the print is fine. When the initial flow control looks wonky or didn’t stick right then the print will fail if I let it go. Thanks again for the replies and things to check out.
