I know this has been asked before, but I wanted to see if the community had any other sage advice… I unpacked the P1P yesterday after a move to a new location, got everything setup. Calibrated the machine, loaded PLA to make sure it was all working, everything looks good. Hooked up the AMS and imm…

I am glad that the issue is solved, and thanks for sharing. That’s a typical event in the AMS (at least for me). Sometimes, the filament breaks inside, and you must disassemble and remove it. What I didn’t understand was where your filament was broken. In the hub or the feeder? @okokok , thanks fo…

For me, it occurred that when I made space in the AMS for a different filament and then put the old one back in (Amazon basic) after taking it out, it always had those ridges from the pull-in motor. After cutting off the part with the ridges it worked again for me

It was in the feeder, which is why I didn’t see it. Now I know where to look :slight_smile:

Was it complicated to take apart?

Mine filament broke under the AMS had to disassemble the whole AMS top layer to get under the ptfe tube to release. and pull the filament out. first time looking under the ams, those ptfe tube on slot 4 and 1 takes quite a tight turn to get to the extrusion point of the AMS.

This is what I found just happened to me. I could see the printer thought filament was loaded. I had found a piece of filament that had broken (brittle towards the end) and removed it and it still thought there was more. I did cold pulls, etc trying to clear it. Finally figured it had to be in the…

So I also have this error message, but in my opinion I don’t have a broken filament I checked all PTFE tubes by hand for friction, partially replaced them and also optimized the bending radii. If I remove the PTFE tubes at the moment the problem occurs and pull the filament in different places by …

My issue was quite different. But, the replies here have been helpful. At first, I checked through the ptfe tubes. This is an important check to identify if any filaments still stuck inside. Highly recommended step. For me, there was no filament stuck in the ptfe tubes, including those in the ams. o…

I purchased my P1S a few weeks ago with the AMS. Has been printing find with PETG but changed to PLA last night to print another model. AMS loaded filament, bed levelling was fine and printer started printing but no filament was being extruded. I stopped the print and the AMS tried to unload the fil…
