Old Duet 2 WiFi 3v regulator problem
-
Hi!
I have a genuine but old Duet 2 Wi-Fi v1.03 that is not booting anymore.
I haven't used this printer in a while but decided to start using it again today.
When homing Z with the Precision Piezo Orion probe, the printer died. Before starting the print I tested the Z-probe, by taping on it and tested the heaters and steppers.It restarted and I checked the logs but could not see anything more than that it had booted today and no errors, last boot before today was 9 months ago according to the log.
I tried to print again, and it died once more but doesn't boot up anymore.
The 3v led is not powering on. So, after some searching here, I disconnected all connectors, the DueX board and the SD card and tried powering by USB.
The u2 3v regulator gets hot but nothing else, not the SD, Wi-Fi or processor.
My electronics knowledge is close to none so my question is if it would be enough to change the regulator (have to find and pay someone) or if I should just "recycle" the board.

@TypQxQ Yes, you can replace the 3.3V regulator on the board. It's not too difficult a repair, so I wouldn't have thought it would cost much to do. A list of regulators used is here: https://docs.duet3d.com/en/User_manual/Troubleshooting/Parts#voltage-regulators-1
It's possible age killed it, but could also have been a short; it's rather difficult to say if anything else has failed.

@TypQxQ if the 3.3V regulator is getting hot then most likely another component has failed. Is anything else getting hot? Check the SD card the WiFi module and the microcontroller in particular.
