I have been experiencing consistent errors with Slot 3 on the AMS Lite, making it difficult to use. Specifically, I encounter errors every time it would like to change colors, such as “Failed to pull out the filament from the tool head (1200-8015-032113).” Sometimes, I can resolve the issue by pressing resume, while other times, I have to manually assist by pulling the filament gently at the spool. I also receive errors stating, “The AMS1 Slot3 motor is overloaded” and “Unable to feed filament into the extruder (1200-8006-032122).” At times, simply resuming the process works, while other times I need to gently push the filament at the spool to resolve the issue. The yellow button on the AMS Filament Funnel Unit for this channel is harder to push than the others. Additionally, the spool seems to not turn automatically like the other units. The unit is relatively new, (only a few weeks old) with just over 200 hours of use, and Slot 3 has been the primary slot I’ve been using. I’ve already put two full rolls of Bambu PPLA Basic White through this slot. However, this new issue has now made Slot 3 unusable, as errors now occur with every filament color change to and from this slot. Once the filament loads, the printing is perfect, but I’m keen on being able to print in 4 colors.
Take a look at the rollers of that slot. Sometimes one of them is not sitting correctly.
Thank you, after reading some threads today it made me start to think about having to take apart the Filament Funnel Unit, since that was the primary channel I was using. I was thinking maybe gunk filled up around the rollers. It is just the instructions looked a little complicated.
Update for anyone that has this issue.
I did take apart the AMS Lite Filament Funnel Unit. This instruction a fairly strait forward, just be sure you understand the gear location when you put it back together, Although I did not find anything in the unit out of the ordinary, I did clean the gear that pulls the filament and put it back together. All seems to be working right now.
