Same with my a1, when the filament goes to poop, the ams tries to push the filament into the spring thingy, and it just ends up retracting a little. Every time it does this, i just take out the ptfe and then push the filament out, and then stick the filament into the ams slot while pushing the lever on the left of the head. Any idea how to fix, im getting pissed that i have to do it every 5 mins.
