While reading the info for the copper nozzle and block, I came across this from the copper nozzle page:
Combine with our plated copper blocks for the ultimate extrusion pairing. No need for hot tightening, this pairing just works.
There’s no mention of that here, or anywhere else that I’ve been able to find. Is it still recommended to do the hot tightening when you have both copper nozzle and block?
Also FYI, this guide says to unscrew the nozzle a full turn, but the Heater Block Metal Assembly guide says 1/4 turn.
You could suggest pushing on the heater and thermistor from the other side, as an alternative to tugging on the delicate wires.
Once they have, you'll be able to view a graph of their reputation gained over time.
Here's a preview of what the graph will look like:
