m997 s1
Trying to connect at 230400 baud: failed
Trying to connect at 115200 baud: failed
Trying to connect at 74880 baud: failed
Trying to connect at 9600 baud: failed
Error: Installation failed due to comm write error
ok

No dice unfortunately, any other thoughts?

@CNCModeller hmm, thats not a particularly good sign.
Did you send M552 S0 first?

Yet another not good sign...

m552 s0
ok
WiFi module disabled - start timed out

@CNCModeller if it won't go with M552 S0 then M997 S1 its probably a failed module

Is that something that can be fixed?

[jay_s_uk]

@CNCModeller replacing the ESP8266 usually fixes it

it as OK last night but not now its installed in the printer.

So it was on wifi outside of the printer but now it's having issues? Have you tried removing it and testing it on the bench? Maybe a short?

Yeah, the diagnostics above were out of the laser and back in the office, and I can't get any response. I replaced it in the laser with another Duet2 board and the replacement is working fine. Guess it's a dead wifi module as per the above diagnosis.

When and where was it purchased?

That's all in hand. The supplier has offered a replacement item. I'm not desperate for it as it's destined for upgrading my Wanhao D5s sometime in the near ish future.

Note to whoever repairs this board: yesterday I identified a QC issue with the soldering of the wifi module to the PCB on a different board variant. This is likely the same issue. Resoldering all the joints using no-clean flux, hotplate and fine-tipped soldering iron will probably fix this.
