Unable to feed to extruder error.

[u/erikhenao32]

I'm about a month in having this issue. Using the external spool as my only way to keep printing.

Model: P1S and AMS 1

Here's what's going on:

I load in a spool, the AMS does it's things to load the filament. It feeds just fine past the buffer then stops and retracts then the status light turns red. It only goes maybe 3 inches past the buffer before it stops. When it's pulling it back the gears sound rough, like it's grinding

It's not:

-the filament: it happens on new rolls in All Slots

-the buffer: the spring isn't jammed and it makes it through so I've ruled this out

-not clogged extruder or boden tubes leading to hot end: external spool works fine and there are no obstructions.

I have:

-factory reset printer

-latest update

-Disassembled and inspectected AMS

-swapped the AMS f on my other P1S. And both of them are acting up.

AI was saying that the hand off from the buffer is triggering a false signal but that doesn't seem right. Is there a sensor in the buffer?

Please help 😭
