I am a new user and I am trying to learn printer, but last 3 days I couldn’t finalize any print outs due to spagetti failures or bed adhesion problems. I only used 2 kg of filaments including bambu sample,and until now I had 2 broken filaments inside extruder and hotend. I learned how to solve these issues. on the otherhand, now I am trying to print even benchy and I am having bed adhesion problem. I used same brand for all from begining. first week all prints were flawless, but now all spagetti or first layer problem. I have upgraded firmware, then downgrade, now again upgrade but no solution. is changing hotend a solution or should I change texture pei plate. I am open to solutions
have you washed the plate with soap and water?
You also may need to dry your filament, when pla gets moisture it gets brittle.
You haven’t loaded up the support filament that you got with the printer? It’s a common mistake.
Yes I have done it several times, thanks for advice now I started to use other side of plate
moisture level is 2 now so I haven’t thought of it, thank you for advice, next I will try that one, on the other hand all filaments are almost 3 4 day before opened
Thanks for advice but it is not about supports. now printing starts and after 30 layers it removes from its location so it gives spagetti failure
Use some of the Bambu glue stick. Not much is needed. Leave the door a little open.
Thanks for advice, I also tried that instead of glue I used hair sprey and door was open in various conditions. Now I decreased part fan to 90 % and cooling starts after 5th layer, door is closed and it seems working until now 75 % work is completed and no problem. I had no problem with part and it is going on. it is a low poly rabbit figure to try. next time I will try a little complex part to see. but it is intresting that, stock settings were working and after a clogg in hotend it started to fail.
A clog will almost always leave filament behind. Follow this video on how to do a cold pull. You may have to perform the procedure several times. Use white or a light color filament.
That still looks like a dirty plate to me. Give it a good scrub with dish soap and hot water. Be very careful not to touch the build surface once it is cleaned. You can also add 5-10 c on the bed temperature and be sure the door is closed during the first few layers.
Actually it is just cleaned and bed temperature raised to 65, door is closed and I set part fan after 5th layer. on small model such as 3d benchy I have no problem, but for large surfaces is not holding plate. I am not sure may be since material is not cooled down this happens. and an addition machine is almost new not too much used especially for large models
Bambu recommends open door and top for PLA, PETG, and TPU.
The only time I do not follow that recommendation is when my semi-heated shop is below ~24 °C, in which case I preheat the closed chamber to 28 °C with the bed, and then open the door and top if chamber temperature approaches 35 °C.
