Wobbling nozzle
I've changed my nozzle due to a clogging. I've twisted the old nozzle out after heating the nozzle to about 260 °C. This took quite some force.
Now I've tightened the new nozzle with the most force I could apply. And it seems that block that is holding the nozzle is wobbling. At some point after tightening the heatblock should stop wobbling right?
I've tightened the nozzle at a flucuating temperature of 260-285 °C
Here is video of the nozzle at about 100 °C still moving freely.
What should I do here?
Re: Wobbling nozzle
Remove the nozzle, let everything cool down, then remove the heat break (with heat sink) from the heat block.
Screw in the nozzle as far as it will go and unscrew just over quarter of a turn.
Screw in the heat break/sink and hand-tighten.
Heat up to 250-odd degrees and tighten the nozzle, ensuring that the heat break/sink don't unscrew.

Worked like a charm. Broke my cooling fan in the process sadly. Hopefully I can order a spare one.

Done that a few times. Note to self: Always let the extruder cool down before trying to screw up the fan.

I've got quite a collection of fans with broken/missing fins. I always tell myself I'll be careful and not hit the fan but I never listen.

Every time. I am sooo confident that I won't damage the fan blades... 😀 😀
