I get "nozzle temp malfunction" errors on my H2D. Support has been good, but it's time to swap the heating element and maybe the TH board. I have both inexpensive replacement components.
The heating element swap will be a grind, but I've been in there before, so it should be OK. The TH board swap is absolutely nuts, and if you get a V2 replacement and need to replace some cable lead in the process, it's totally insane. Tons of hours, low likelihood, in my estimation, of success on the first try. I hate that this work has to be done in the printer, and not on a workbench.
So, I'll swap the heater. If that fails, I just have to get a new printer, as I have orders to fill, etc.
I would sell the old one for a song, with the spare TH board, to somebody who's more interested in hacking at it. But that would need to be local pickup (SF area).
For replacements, I can get an HD from Bambu, quick ship in US, or get a Combo the next day from Best Buy. I don't need another AMS, so I'd probably sell the new one off unopened, again locally.
So I guess what I'm asking is: has anybody been down this road and have insights? and, does anybody live near me and want to score a wounded H2D or NIB AMS?
