Preventing unscrewing while changing nozzle

janjoh

Sooo, what are your favourite way to prevent/minimize the M12 unscrewing while changing nozzle?

Running a Mosquitto with aluminum adapter.

@janjoh This forum in for support of the Duet 3D series of controller boards, printers that are controlled by them and probably e3d hot-ends, but we don't get much of that kind of help request.

I think you'll get a more helpful response if you post on a forum for your printer or hot-end.

But maybe someone here has that hot-end and can respond.

@alankilian I had similar thoughts at first but then I noticed that the OP had posted under the "Smart effector for Delta printers" topic. So I guess the question is specific the the Duet smart effector.

You would be correct.

I understand the smart effector is the mount, but I didn't know Duet also made the Mosquitto hot-end!

I learn now stuff ALL THE TIME from this forum. You folks are wonderful.

@alankilian They don't it's made by Slicer engineering in the US.

@alankilian Nah, they don't. That is Slice engineering and the adaptor is 317Maker. But the issue is the same with the Smart Effector Supplied E3D-style heatsink.

@janjoh few days ago I fire up my delta to do a small print and as always I run a G32 before i start printing when I notice that the nozzle smashed harder on first probe point than usual...I immediately push the emergency button and power off the printer after let is cool down...I then had the smart effector unplugged to understand what happen only to see that the m12 nut securing the heatsink was slightly loose( I don't understand how could that happen, maybe the vibration when printing fast did that)
I just put a small amount of hot glue on the heatsink threads and fastened the m12 nut...I'll see if unscrew again in next few days!

janjoh

@weed2all Yeah, that works for vibration. But when unscrewing nozzle it does not hold.
