Can't Print Silk PLA

Bambu Lab H2 Series
1

I have a new H2S with about 140 hours of printing time on it thus far. For the first time I tried to print Generic Silk PLA multi-color using the AMS2. I changed the filament settings accordingly and got an error and it wouldn’t print at all.

I changed the filament to a different spot and got the same error message. Changed to a different roll of filament, thinking maybe I had a defective roll. Again, same error and wouldn’t print. I don’t remember exactly what the error was but after checking online, it seemed as if I needed to make some manual adjustments to the printer if I’m going to use Generic Silk. Tried drying the filament for several hours today and tried once more. This time I got an error (different from the last two) saying it is unable to feed filament into the extruder due to entangled filament or a stuck spool. Checked this and I don’t see that as the problem.

Printing now with a standard generic PLA (NOT Silk) and it’s printing fine. Can’t figure out what I’m missing here. TIA for any help/suggestions.

Did you set the filament type on the machine to match the slicer?

whats the error?

This time I got an error (different from the last two) saying it is unable to feed filament into the extruder due to entangled filament or a stuck spool.

Visually inspect the PTFE line as it tries to load.

  1. Does it clear the buffer/hub before you get this error?
  2. Does it enter into the final bend of the PTFE line before it enters the top of the toolhead?
    2b) Do you see it get caught here?
  3. Does it make it far enough to generate a poop, but fails after that and before printing?

It may sound silly but try snipping the end of your filament off again, flatly, send it back thru and see if it gets caught again.

Silk filament can be quite challenging to work with — issues may arise from incorrect bed or nozzle temperatures, or other related factors.

My first and only attempts produced a visually nice model, but with extremely poor strength :grin:

did you install funnel savers ?
this cursed spool has the same quantity of filament of the working ones ?

UPDATE: Thank you all for your replies and suggestions! I did snip the ende of the filament again - flatly. I know I snipped at an angle before. I was able to successfully print a benchy so I’m thinking I should be good to go now moving forward.

Thank for your reporting the update and fix for the problem. I’ll definitely keep this in mind.

With Silk, slow down the printing speed to get shinier/smoother results, mess with the

Max Volumetric speed

Generic silk defaulted to 7.5 for me, try 3 or 4 and compare results. Prints will take longer but should be better quality, potentially.
