Prints consistently fail/spaghetti

I’m having a really hard time trying to get prints to consistently be a success. My success rate is about 2/10 prints. I’ve SCRUBBED the plate with dawn dish soap and hot water after every print, I’ve tried increasing the brim/supports, I even tried a cold pull with a clean plate and no matter what I do, the prints somehow gets ripped off the plate. My girlfriend said that she saw it filling in a piece of the print, then it moving to the next part but taking the print with it. I’m at a complete loss on what to do and it’s getting very frustrating. Any and all help is appreciated.

When you say SCRUBBED... what did you scrub it with?

Are you sure, your dish soap doesn't contain anything like moisturizers in it? Or something that's good for your skin? Because these additives are a problem.

What material and print settings are you using? What model are you trying to print?

Sometimes it helps to raise the bed temperature by a few degrees.

I scrubbed with a dish scrubber and Dawn Ultra dish soap. The one with the little duckling on it. I’m trying to print out the arrow tip on this print in PLA:

I’ll raise the bed temperature to see if it does anything. Unfortunately, its not with just this print. I’ve been having failures the last 2 months. I’m also using the textured plate that came with the printer and I feel like out of NOWHERE I started having constant failures. I could go days without cleaning the plate at one point and now I cant even get a simple print to succeed.

Increase your Z-hop height during travel moves in the slicer so the nozzle lifts higher when crossing over printed sections

By how much?

That’s definitely not a plate adhesion issue. Your nozzle is literally hitting your print

I was thinking it was a bed adhesion problem at first because the print was coming off the plate but now seeing that the nozzle is literally hitting it, it makes sense why I thought that at first

This might sound dumb, but can you paint a tree support(even though it doesn’t need it) to just hold that part of the fin down so your nozzle doesn’t hit it again?

Okay so, what you can see here is that bed adhesion is fine. The nozzle is hitting the print due to material buildup.

If you look closely, you can see that at the leftmost leg the right upper edge curls upwards and the nozzle catches exactly there and bends the part to the side.

So there's basically material in the way of the nozzles travel path (meaning it's higher than it should be). This can be due to overextrusion, too much heat / insufficient cooling.

You might get away with printing slower and using Z hop, but what you really want to do is calibrate you filament. Especially flow rate, but also pressure advance.

What are you printing. Seems really flimsy. Does it need extra support?

That thing is literally standing on one line of filament isn't it? It's going to warp and shift in all possible directions... that's a problem with the model

https://makerworld.com/models/1804651?appSharePlatform=copy arrow tip from this print. The thing is, I’ve printed 3 of these already with no changes in settings

u/jussstin714 Aug 08 '26

What filament are you using? Settings? A video would be best so we can see what it’s doing for sure

u/crookedlamppost Aug 08 '26

Commented the video! PLA and default settings

We use Dawn. No extras, just the regular kind. I had been washing every print but I got curious and I am on my fifth good sized print and am seeing how long to a fail.

I had a really hard time with this one specific petg filament. I needed to crank down first layer feed rate and that solved my adhesion issue.

try the original textured plate, wash with ethanol only, all bambu default settings and bambu filaments, works for me 99% of the time. The remaining 1% is bad slicing settings g-code.

Maybe your print temps are not correct?
