AMS first stage feeder issue

[tutankhamen77]

Hello everyone. I’m trying to investigate an issue with one of the first stages feeders in my bambu AMS. There is no broken filament or any other abnormality in it’s channel. The feeder module looks ok, i.e. I don’t see any contamination inside and it looks like it detects when I insert filament.

Any idea what could it be?

Thank you!

AMS Slot 4 - Red Solid Light

So as the title says, slot 4 on one of my AMS units is solid red. It apparently thinks that there is filament loaded between itself and the AMS Hub [Screenshot 2023-11-03 at 2.08.35 PM] I have broken down this unit, cleaned it out, replaced the first stage feeder with a brand new spare I have for justInCase and internal PTFE tubes, swapped in a brand new AMS Hub I’ve opened a ticket, but have little expectation of a quick response, so here I am … anyone have any ideas on what else this can …

Thank you for the advice, but I already checked all the recent AMS related threads on this forum, but I wasn’t able to find exactly the same symptoms. Regarding the topic you recommended - I don’t have permanent solid red and there is no false filament detection if no filament is inserted. Also, i can manually load filament and push it it all the way to AMS output PTFE, i.e. there is no broken piece inside.
