Shutting down USB interface to update main firmware. Try reconnecting after 30 seconds.

This did not fix the issue.

@Handiwork7 that doesn't look good.
when and where did you purchase the board?
one for @Phaedrux or @droftarts

This is a Workbee CNC, purchased from a private seller. The unit was working following an upgrade directly from workbee then reboot and all is dead.

@Handiwork7 If it was working before, an RRF firmware update should kill the WiFi module, and neither should a WiFi module update.

Do you have a PanelDue connected? If so, please either switch it to the 'Setup' page or disconnect it while updating the WiFi firmware (the serial communications from the PanelDue can interrupt the update process).

Sadly, I do not have the PanelDue.

@Handiwork7 Try this:

Turn off the Duet, remove the SD card.
Turn on the Duet and connect via USB. This will mean the WiFi never gets initialised.
Put the SD card back in, and send M21 to mount the SD card.
Then try either:
- sending M997 S1, or
- start again, but send M552 S0 to turn the WiFi on in idle mode, then send M997 S1

This was probably caused by a failed WiFi firmware flash during the main firmware update, so the WiFi firmware is only partially there. Possibly the WiFi firmware flash took longer than expected, and the Duet reset before it had finished.

When you turn the Duet on, I think the WiFi module gets hung up trying to enable networking with the M552 S1 command in config.g, so removing the SD card means this doesn't happen. Hopefully then the Duet can flash the WiFi module, as it should be off, or idle.

@droftarts Thank you!

Earlier today I replaced the WIFI Module with the Ethernet module from a faulty board I had years ago (drivers died, I kept the board for spares). (Save make/version etc).

The Ethernet module was recognized, I can set the IP etc. Sadly, It's still showing "Link Down" with the Ethernet cable connected.

I can only assume at this point one of the traces are damaged on the PCB and the signal is not making it back to the atmel chip.

I do have a full re-flow station and microscope. Just not sure if its worth the dive vs go just buy a new one.

The schematic for your Duet 2 board is here so you could probe the connections back to the MCU and see if there are any issues there.

Did you ever get it working?

@troydeming This thread is pretty specific about replacing a WIFI module with an ethernet one. We can discuss your setup in the initial thread you started here:
