Filament stuck in AMS slot

Hi,

I purchased an X1 Carbon w AMS from Microcenter last weekend and bought a few Inland PLA boxes from Microcenter at the same time. I tried loading filament in slot 2, but the AMS pulled the filament slightly and then got stuck. The filament in that slot is stuck and I can’t unload it.

I put in two other filaments that are also Inland PLA in slots 3 and 4, and had no issues there loading or unloading. Has anyone dealt with this issue, and if so, how did you resolve it?

I ran into this on day 2 of having the X1 Carbon and AMS. I cut the filament at the print head, detached the fittings that hold the tubes in. Had my son hold up on the gray tab in the AMS that releases pressure off the filament and then i pulled really hard. Might not be the best way but everything works fine after…

Thanks for the response. I tried that and the filament came out, but now the same slot just won’t load filament at all. Slots 1, 3, and 4 work fine, but now I get a red light flashing in slot 2 when trying to load filament.

You might have filament stuck in the path (PTFE tubes) in the AMS itself.

For the AMS (not AMS 2) you have to:

Remove filament from the AMS
Disconnect the AMS from the printer
unscrew the two hex bolts that are now exposed since you removed the filament
under that cover you can see four short PTFE tubes, you might have something stuck in there

Here is a good video on how to check the ptfe tubes
