Jammed Nozzle help - CTC: Makerbot Replicator 2X

[CTC-USA]

Your welcome.

POWER OFF - Unplugged

Loosen the hex key for the said hot-end. Then lower the bed all the way.

Disconnect the connections for the heater cartridge, etc.

Your Nozzle/assembly should then fall out. If you have filament stuck inside. Cut it between the BLACK extruder housing and the large aluminum carriage block.

You may need tools, but unscrew the nozzle from the aluminum (small) block.

Then you can unscrew the cooling tower.

Under no circumstances should you run the hot-end without the PTFE in the nozzle assembly. You will ruin the entire cooling block, nozzle and PTFE. Just a fair warning.

Screw in the nozzle all the way flush FIRST, then the cooling tower. You'll note the cooling tower has 1-2 threads exposed. Normal.

This step is not done from the factory, so initial nozzle height is not optimized.

*Edit - The nozzle and PTFE are two separate products. They are known as wear items, and are rather general in the marketplace. Youll be looking for 3mm inlet Nozzle, and 3mm PTFE.
