Failed Print. Bambu Pla

So i picked up an X1 carbon off facebook a few weeks ago. Previus owner only printed on it a few times. I printed in PLA and PetG with good results.
The last few prints were Petg.
I had some stringing with Petg HF but i seemed to have cured that with an Auto calibration.

So i went back to Pla for a few prints and i get this.
Bambu basic Pla.

Welcome to the community.

This can’t be right. Filament does not flow at this temp.

You could try to increase the temp of the filament but check the basics first and print a first layer primitive using stock settings.

If you haven’t done a first layer before, here is how to do it.

  1. Create a square primitive by right-clicking and adding a cube.

  2. Scale the cube to 200x200x0.20mm which will create a single layer sheet.

From there you can quickly tell if your filament is flowing correctly. A properly calibrated filament should flow very smooth.

I’m assuming the screenshot was taken after the print was canceled and the nozzle was cooling down.

Correct.
I was watching it before it failed. Tenps were normal. I canceled it

Ill try it. Thanks.
Just crazy how ot printed basic fine before but now its not.

Is that some filament blobbing? Perhaps the silicone sock, or nozzle has some build up?

It might be but hard to tell. To do a decent inspection, you have to take the magnetic cover off. Also, I found that this tool is perfect for inspecting the nozzle from underneath.

You want the version that has the rotating lamp so that you can aim the light. I purchased and returned 3 of these because they all have fixed lights which is damned-near useless in my experience. This one pivots the LED so that you can aim it properly onto the nozzle.


These are not easy to find. There are hundreds of BS Chinese vendors spamming Amazon with the same cheap product. They all have two things in common: they don’t have a pivoting lamp, and the battery holder needs to be unscrewed. This model is what you would expect from a proper light—it has a snap-on battery cover with no tools required and no small cover screws to lose when swapping batteries.
