E-Series How to Remove a Stubborn Hotend Jam

E-Series - How to Remove a Stubborn Hotend Jam

We have all experienced a stubborn hotend jam at least once in our 3D printing career, but for those of you that are experiencing this for the first time, here is a simple How-To on removing some of these stubborn hotend jams.

1)  Frist, remove the bowden tube from the extruder. To do this, push and hold-down the  black collet on the extruder block, then pull upwards on the bowden tube to release it from the extruder -- please note that you may need to release the extruder tension on the filament to perform this. To release the extruder tension, rotate the tension screw counter-clockwise a few turns so that the filament and bowden tube may pull out more easily.

2)  Next, we will perform the same procedure on the hotend side. Remove the blue retaining clip then push and hold-down the black collet. You may now pull upwards on the bowden tube to release it from the hotend. You should now have direct access to the filament sticking out of the hotend.

3)  Now, heat the hotend to 10°C above your normal printing temperature. Once the hotend reaches the set temperature, firmly grasp the filament and pull upward to remove it from the hotend. If done correctly, you should have removed the stuck filament and resulting plug from your hotend.

4)  Lastly, reassemble the bowden tube by performing these steps in reverse; re-insert the bowden tube, lift the black collet, and re-insert the blue retaining clip.   Et voilà!
