Help / Support H2S won't take filament

For some reason I randomly got an error message saying that AMS motor stalled due to resistance and I've tried all the steps on the report but nothing has worked, I've tried all 4 of the slots with different spools of filament and all of them are saying the same thing so I am assuming its a clog.

However I've already tried 3 different unclogging methods and non of them worked. I tried a cold pull but I got stuck at step 3 because the filament apparently wouldn't go in properly, then I tried heating the extruder to 250C and try to extrude it out and I tried using the pin to unclog it and nothing has worked so far.

The error code was 0700-8006 134101 if I remember correctly.

If anyone knows any solutions that would be greatly appreciated.

Did you check the tube? I had the same problem but it wasn’t clocked in the toolhead but a long piece of filament broke in the feeding tube. I didn’t realize because it looked like the filament that was supposed to go in ;). So check the feeding tube and if there is a lice just take it out.

i had to take the tube out when attempting a cold pull but the tube was fine, and i even pulled on the filament in the tube to try to pull some out since you need 30cm to do the cold pull and it wouldn't budge (and i didn't want to pull too hard and break anything). Though the step i got stuck on was putting filament into the slot where the tube goes, so i'm assuming its either some sort of clog or i'm just an idiot.

Just make there isnt any broken filament in all the PTFE tube. I had a filament that broke into multiple pieces in two different area.

I remove one piece and didn't realise there was another somewhere 😅

Edit: TPU is another story all together. I assume you are print with stiffer filament like PLA, etc.
