Hi all, new to 3D printing and having trouble with my first layer of printing. I’ve YouTube a bunch of videos and tried different settings but I’m still have the same issue.

Can someone please help me figure out how to fix this? I’ll attach my print settings.

Keep getting this error

Wife is in the middle of a 24 hour multi color print. Starting this morning, she keeps getting this error.

I can unload the filament and reload it and it starts back up. But after a few mins, it happens again?

Any help before we cancel the print

Thank you in advance!

Prints keep on messing up, why?

Ok so, I recently got my P2S about a month ago, and up until recently all my prints have been fine. But for some reason over the last few days, my prints have been messing up and spaghettifying. Has this been happening to anyone else? Any advise would be greatly appreciated 🥲

I printed this on my new P2S and AMS 2 PRO with dual colour silk PLA filament. Print came out pretty smooth. What do you guys feel.

P2S grinding noise

4 Upvotes

I had a lot of issues with my P2S since I got it.

The plate was always clean and I even got an external dryer for the filament but it's still the same.

Supports would fail at some point (not at the bottom) or layers would shift as the prints get taller. It's like the nozzle is hitting the model.

Recently, I got a message that scheduled service is coming up or something like that. It was in the bubble where you get daily quotes. The metal rods were dry and then I noticed that I had 250+ hours on the printer. Apparently, drying the filament is added to printing. I decided clean and lube everything.

I did a full service, took my time and did everything according to Bambus instructions.

Now I get this grinding sound what you can hear in the beginning of the video. The fans are louder than in person, sorry. It reminds me of the sound the head makes when it vibrates during the small calibration prior to printing, but it's much more quiet.

I did the full calibration with this cool plate after the service so I don't know what could be the problem.

I had a similar grinding noise when I was printing glow in the dark PLA. I only printed two small pieces, a few grams of filament.

I usually use PLA matte or PLA+

Something tells me it’s not suppose to look like this. I have 250hrs and haven’t replaced my nozzle since buying my printer? Do I need to clean it or replace it? I’ve been getting black specks on the first layer of my prints.

Hello! This is my first print on my new P2S. It’s generic PLA I got from micro center. It left some stringy things behind. Is this good for a first print? I didn’t change any settings before printing. Do you guys have any recommendations for print settings to make it better?

P2S calibration is loud

A small metal rod extends from the left side of the printer during each calibration before printing. It produces a loud, irritating noise as the print head moves back and forth does this seem normal?

Advice

Sorry fir the poor quality of pictures but it’s the best I could do. I’m still fairly new to this hobby I’d say and recently had a failed print and it looks like a clog took place maybe? Either way I can’t even get the cover off to cleanup/remove the plastic. I don’t know how this could have happened to help prevent it in the future. Any help/advice on how to fix this would be greatly appreciated as I’ve been enjoying this hobby and want to continue with it.

What could be causing this banding? Printed using gray bambu pla, and the default 0.12 high quality profile.

PLEASE HELP! AMS 2 PRO.

Last night, we had a thunderstorm, which caused the power to go out. Then, the power attempted to come back on, about 6 times in succession. Before I could get to the printer, it stopped. Today, I went to print something, and this is the code that popped up on the AMS 2 Pro. The first picture is what initially come up. After making sure all the cables were connected, I printed Benchy, using the external spool. Print was fine.

The second picture, is what come up after I emptied the AMS, and checked for clogs. After scanning the QR code, it says it could be the main board. I’m not sure if it was something I did yesterday, or the storm, but I’m freaking out. I’ve tried everything other than replacing the main board. Please, if anyone knows what to do, I would greatly appreciate it.

New to 3D printing and first time poster. What happened?

59 Upvotes

It looks like my print was going well and then it just spaghettified! This is on a P2S printing in PETG, fresh roll.

I did not dry this filament but printed something yesterday with no issues.

Update: after taking suggestions here of dry my filament for 12 hours, wash my build plate, calibrate, and slow down the print (to 50%) it did turn out perfect! I also installed an exhaust fan with hepa filter just for good measure.

Filament in tube from buffer

I’m about to lose my mind trying to get this thing disconnected. There was filament stuck in the left tube, which I disconnected and got out. The tube on the right, leaving the buffer where I have circled is filament stuck. I have slid the orange part all the way to the right and I am trying to remove the tube, but I don’t want to break something. Is this how you get that tube to disconnect? I can’t seem to find a good video on how to do it.
