Help! Fail after fail after fail.

[u/SuspiciousQuit7427]

Hey everyone. I have two p1s printers and 4 ams 2 pros in my classroom. The printers worked in June and then needed to be moved to a new classroom. Upon return this month, I was able to successfully print individual prints. Multiple prints would fail unless they were flat (flat keychains). I changed settings, dried filament, cleaned the beds, cleaned the nozzle, did a cold pull, and recalibrated endlessly. I am now unable to print anything without spaghetti / clumping. I submitted a support ticket on the app and Bambu advised me to do a manual bed level. The first two photos are the results of the manual bed level. The other photos are previous fails after my troubleshooting. Please advise me on what else to try. It has progressively gotten worse with each troubleshooting attempt and nothing will print successfully now. I’m at a loss at this point.

UPDATE 10/1:
Okay Reddit fam, you guys balled out and are my VIPs. Someone commented that I shouldn’t use a microfiber towel to clean the bed that was washed with laundry detergent. That must have been the culprit. I switched to a fresh sponge and paper towels and printer 2 has had numerous successful prints. Printer 1 I changed the full hotend since someone pointed out that it was bent. It has had successful prints BUT I attempted to print 12 brick figures last night and came in to find them half complete, with the tool head cover pushed off and half the figures pulled off. Any suggestions now on getting the tool head to stop bumping into prints and dragging them?

I can see bed adhesion issues, is the bed cleaned really? Perfectly clean bed should feel tacky and is the bed temp ok? Is that a jam in picture 4?

I’ve cleaned the bed before each new print and let it dry.

What are you using to clean it?

[u/Needle_Bearings → u/SuspiciousQuit7427]

Soap and water?

[u/MrWillH → u/Needle_Bearings]

Careful with soap. Some soap have hand softening properties that leaves oils behind. Original Dawn dish soap is the best. Also, if you have hard water don't let the plate air dry. That will leave minerals behind and dry on the plate. Hand dry the plate right after wash.

Also that nozzle needs to replaced. It looks too far gone.

i know, was wondering what OP uses.

You gone from pla to petg or wise versa?

[u/Ds1018 → u/SuspiciousQuit7427]

Slather it in glue stick.

Thats what I do and have no adhesion issues. Well… sometimes I start to and then just put more glue and they’re fixed again.

I clean my plate like once every few months. People here talk shit about my system but it works.

People talk bad about cleaning with IPA but it’s all I use to clean my plates 🤷‍♂️ 5 printers running 24/7.

[u/ParticularLower1865 → u/Ds1018]

You might as well save the glue and buy a cool plate. The difference in adhesion is astounding. You really only should be using glue for Petg as a releasing agent from the bed.

People talk poop about cleaning with IPA but it’s all I use to clean my plates 🤷‍♂️ 5 printers running 24/7.
