    • Big thanks to Ian Lewis of Printrbot's Support team for guiding me through fixing my Simple.

    • Your printer's hot end is comprised of two stages. The beige plastic part is a thermal break between the 200C heater cartridge and the feeding mechanism above.

    • The job of the beige part is to keep the filament cool before it reaches the heated element.

    • The part pictured is made with PEEK plastic. http://reprap.org/wiki/PEEK

    • For more term definitions, see http://reprap.org/wiki/RepRap_Options#Ex...

    • Anyway, we're here because this thing is jammed. Read on.

  2. Clearing Jammed Printrbot Simple Metal 2014 Hot End, Pull off the red Teflon "sock".: passo 2, immagine 1 di 1
    • The sock may stick to the brass nozzle. If this happens, use a utility knife to separate the nozzle from the sock.

    • The sock keeps heat even over the hot end. You'll need to put it back on when printing for good results.

    • Heat the hot end to 50 degrees Celsius.

    • Cold plastic fuses the nozzle to the hot end. This is just enough to soften the PLA plastic without being at the full operating temperature.

    • Use your ratchet and wrench as shown.

    • Do not touch the hot end. 50C = 122F.

    • Use a torch to burn off plastic on the nozzle.

    • Continue until all plastic has burned away.

    • Heat the hot end to 230 degrees.

    • Slacken the idler screw.

    • Manually push filament through the hot end. Keep a firm pressure through any resistance.

    • Once the filament comes through the hot end, pull it straight out.

    • Turn off the heater. Allow everything to cool.

    • Power off the Printrbot.

    • Replace the nozzle. Tighten to hand tight then 1/8 turn.

    • Replace the red sock.

Conclusione

Once the hot end is reassembled, heat to normal 200C and attempt to extrude.

Looks like some pictures are missing. Any plans to get those updated?

I used a torch on my nozzle and it completely deformed it. Not every torch will work, be careful. Might be better to use a stove for this.
