How dead is my Duet 2 Maestro?
-
So the SD card appears to have also been fried. It does not register as being plugged in when using an external card reader on windows. That indicates that is likely other damage to the system.
I do get the green 3.3v led, and red 5v led when connecting to usb power only. the red DIAG and reset leds are both staying lit. When connecting to windows, the device shows up as "Unknown USB Device (Device Descriptor Request Failed". Attempts to install the Duet driver are unsuccessful.
I tried loading a new config + firmware on a new sd card, nothing seems to happen when connecting to USB power. Do I need the 12v power in order for the firmware to update from the SD card?
-
No usb power should be enough to flash the firmware just motors and heaters won't work.

no but the firmware could be corrupted; see https://duet3d.dozuki.com/Wiki/Installing_and_Updating_Firmware#Section_Fallback_procedure_Num_3
long shot, if that works then go get a lottery ticket asap:)

I did attempt to use the erase jumper, but I can't tell if anything is happening. When I plug in the device with the jumper installed, it looks the same LED wise. I think this board is truly dead.
-
After you've powered with the jumper on, power it off and remove the jumper, then check to see if it shows up as a bossa port in windows device manager.

I've tried with a few different cables, and it just shows up as an unknown usb device with code 43 error. I'm guessing that means its pretty damn dead. I guess I could try on a linux machine just to confirm
-
Yeah that's not promising.
-
The fact that the USB device has shown up at all is a good sign. Have you tried uninstalling the device driver for it, and reinstalling the driver?
-
I tried plugging it into my linux box, and it powers up, but the system doesn't acknowledge a device as plugged in.
I decided to just buy a Duet 3 Mini yesterday, which should be here Friday.
(I actually bought an SKR V1.4 first, but it's been 5+ years since I setup a Marlin based controller, and I'd forgotten how awful and complex that process is. I truly appreciate the ease of setting up an RRF board, and the extensive documentation you guys provide!)
((Is there any value in sending the dead board back to you for a postmortem?))
-
The Maestro isn't in production anymore, so probably not?
But glad you like the Duet and RRF. Hope you enjoy the mini5. It's a nice little board for sure.
