Homing works, but repeats endlessly (mostly)

@b3njam1n one more note- when I tried to connect to the D3 from the rPi, it would not show up. It completed the flash from windows, and verified. Now I am at a stand.

@phaedrux I think I have lost the power mosfet that provides regulated 12v to the board. I am only getting 3.3-3.6v on V12 according to DWC, and I am receiving an "attempting to move motor while Vin out of range" when I try to move a motor. That seems to be why the 12v fans stopped turning. The external PSU and the power it provides are unaffected, but this duet is probably out of action until I can replace that component. The board is genuine Duet3D, so the part is whatever is specified for a board marked v1.01. It is the mosfet clockwise of the shielded power strip. It says it is a 036N04L GAB830, and when I try to find a replacement at mouser.com it says there is a long lead time. Any chance you guys have one available?

What LEDs are lit on the board?
When and where did you purchase the Duet?
-
@phaedrux I bought it from filastruder. The three LEDs quite near the reset button are, anticlockwise from the corner, amber, red, green. The diagnostic LED us just flashing at about 1Hz- so normal, I think. Although you didn't ask me for it, here is the output of an M122:

@phaedrux hold on, from the docs, it says " 12V will not be produced if only 12V is provided as VIN." -- perhaps I have not fried that mosfet. Is it normal for V12 to sit at around 3.9v if I am providing 12v to the board from a PSU? I would like to send a screenshot...
-
I'm not exactly sure what's going on. 12v VIN should be within range for the motors to move, so that error message is a little concerning. I've asked DC42 to take a look when he is able.
-
It was trying to home before but looping, and how you've got a VIN out of range error? What transpired immediately before that error?
-
@phaedrux I tried the three methods you shared trying to bring DSF in line with RFF on the duet3. First the missing files, and then the bossa flash of the board via USB- I tried from the Pi and it failed, so I flashed it with bossa from a windows box. It completed and verified.
-
And it looks like the firmware was properly applied and the pi is now in sync.
Can you show a photo of the board powered up showing the LEDs that are lit?
Is the Duet powering the Pi? or the Pi powering the Duet? Or are they independently powered?
-
@phaedrux sure just one sec- the Pi is powered by an official adafruit rPi power supply with an added "Pi switch" so I can power it off individually. Taking a pic, just a minute...
-
@phaedrux oh, and the duet 3 is powered by a 12v 360w psu.
-
@b3njam1n I can see the V_FUSED LED is not lit, and it should be. Can you check the main fuse? It’s the one nearest the power input side of the terminal.

@droftarts I pulled each of the two blue blade fuses by the shielded power strip, tested each for continuity, and both passed. Are there test points where I could get meter readings that would help in your diagnosis?
-
Would you be able to remove the board entirely and get a good clear well lit shot of the board with close ups in case we can spot a damaged component?
-
@phaedrux Yes, absolutely, but I am not at home at the moment. I will put it on a contrasting background and take several shots with different lighting at the highest resolution I can to get the final under the upload size cap. It might be few hours, though.

@phaedrux just let me know if you want a close look at any specific part of the board, and I will get another image to you quickly. Here are some shots from different angles that should do the trick:
