To take the Bowden tube out of the E3D hotend, you have to push the little plastic ring down (towards the hotend) and then pull out the Bowden tube.
ATTENTION: Make sure you don't apply too much force on the printer gantry (the 6mm shafts which hold the hotend). If you bend those shafts, then you're in for some replacements...
Now, the interesting question is, why did your hotend clog?
- Did you measure the diameter of your filament (with a precision caliper)? It must be around 2.85mm, and NOT 3.00 mm. Even though it says "3mm filament", it MUST actually be 2.85 +-0.1 mm. Otherwise, it will get stuck in the Bowden tube or even in the hotend.
- Did you install the small fan which cools the heatsink and did you always run it at 100%?
- Is the thermistor mounted correctly / does it show reasonable temperatures?
/edit:
One question to the experts:
How important is it to run the "PID autotune" after switching hotends? Is this function reliable? I have never done it (never actually changed hotends on a printer) myself...
