blown due to running the effector on 24V with jumper JP3 in
Thanks for the response, it was absolutely on-point. I will do some testing to try narrow it down.

I inherited it, and the others, off my neighbor. So i am not out of pocket financially, but also have little recourse to have it replaced (if it is even in warranty).
For some additional info i have done a full factory reset (wiped and re-flashed its firmware) to take firmware corruption out of the equation, however bench-testing showed this had zero impact.
I have a smart effector installed and working well on my delta printer with a duet 2 wifi. I have one issue though, as the LEDs intended to illuminate the print / build plate are not working at all, and have not worked since new. All fans are working perfectly (part and hotend fans) and as the LEDs are meant to light up whenever the hotend fan is working, I am not sure what's wrong without fully disassembling the smart effector assembly to check the traces and individual components.
I have tested on multiple duet boards too, not that that should change anything if the hotend fan is working as it should.
Any advice would be appreciated. Has anyone had similar issues?
So to update this post with my findings, a swap of the duet board into the Tevo with the same wiring, same accelerometer, and same SD card (and config) worked perfectly. The duet board I removed does not show any signs of having faulty solder joints (or bridged) so for now I am at a loss as to what's wrong with it or how to fix it.
@Phaedrux I do, and have tried with multiple.
Thanks for the response @droftarts.
I have checked the voltage being received by the accelerometer and it was around the 3.3v mark. From what I have read that is the expected (or needed) voltage for signals to be at the 3.3v logic level. I did not test the supplied voltage on the working duet, so I will check that. Any confirmation on the 5v vs 3.3v would be welcome.
That aside, swapping boards and/or checking for shorts / unsoldered pins is the next step it seems. I will test accordingly and let you know what I find.
Hi all.
I am in the process of getting an accelerometer connected to one of my Duet 2 Wifi boards to allow input shaping, however I have hit an infuriating issue where the duet board on the machine I actually want this capability (a Tevo Little Minster delta) REFUSES to detect the device. Console screenshots and wiring shown below.
Wiring connectivity overview:
I checked and double-checked my wiring, updated firmware, swapped accelerometers (i bought a few), used shorter cables, wrapped them in foil to shield from interference (clutching at straws) but all to no avail.
As i had a spare Duet 2 WiFi board available, I did a bench-test with the same wiring loom, connected to the same Temp daughterboard IO pins, and the same accelerometer, same firmware versions, and it worked immediately. See screenshot
So as a test I pulled the SD card from the working board, put it in the board giving me problems, and it still errored. So this for me takes system config out of the equation.
So from troubleshooting i have confirmed:
So what from a hardware perspective on that particular Duet board could be impacting this connection? Is there anything that shares the IO that runs to the Temp DB connection? It is overall a pretty vanilla setup so i am a bit lost for ideas.
Thanks in advance for any assistance.
