Please help filament jam
Printer is jammed, filiment wont load behind it so i couldnt push it out with more filament is abs
Ive disassembled it to try to unjam it but this is what i came to

The heat break is that stainless steel thread hanging out of the aluminum heat sink. You can grab it with pliers and loosen it; but you risk damaging the threads.
Another way is to thread it back into the heater block, then insert a nozzle and use a wrench to snug the nozzle to the heat break (as if you were installing a new nozzle, but without the heat).
Once the parts are tight in the heater block, you should be able to loosen the heat sink from the heat break.
To reassemble, repeat the process in reverse.
Be sure you keep the thermal grease on the heat break threads, you may want to add some, just in case. Also, the heat break is fragile, it can bend or break, so don't force things. 3Nm is the torque spec.

As a side note, the filament should easily push through the heat sink and heat break. Try tapping the top end (exposed filament) with a small tool, see if you can get it to travel down the filament path.
Also, grabbing the filament with good pliers and pulling upwards should also work. Any large segements of deformed filament normally pull through the PTFE without issue. You can also depress the collet and remove the PTFE tube to make a hard pull easier without worry.
If these don't work, and the filament was melted well into the heat break, disaasembly is probably best. Along with a new heat break. I recommend a NON Prusa version - unless you are using an MMU. Even then, I wonder.

i fixed it i heated it up in an oven to 250 *C (to soften the inside filament) and then pulled out the top filament out to make room for more incoming filament, then loaded new filament in and it pushed it out

- Option 1: Let it soak in acetone overnight. ABS will dissolve. If it's classic ABS. MABS (aka ABS-T aka EasyABS) will not dissolve.
- Option 2: Drill out the ABS with a 2.00 mm drill bit by hand. The smallest inside diameter in the heatbreak is 2mm, so the drill bit will fit. I've done that that with stuck Nylon-Carbon filament.
- Option 3: Remove the heatsink carefully by screwing it off. Heat the heatbreak with a heatgun until the filament can be pulled out. Reassemble, including applying the special thermal paste from E3D.

Great. Did the plastic push fitting survive the heat?
