Duet3-1LC accelerometer doesn't work in 3.4 (M956)

jay_s_uk

@megamannen does it have a diode on the underside of the board need the edge? It's been added after manufacture so should be easy to spot

Megamannen

@jay_s_uk I don't think so, didn't see any components on the underside. Which edge? It's currently mounted and a bit difficult to look at the underside.

But how does it explain why it works in 3.3 and not in 3.4?

@megamannen it's on the bottom left of this image

It has something to do with the INT pin but I don't know why it would work with 3.3 and not with 3.4

@megamannen are you certain that the accelerometer is able to collect data using RRF 3.3? In RRF 3.4 we added an extra check to help diagnose a situation in which the accelerometer appeared to be working but didn't collect data when the interrupt signal was missing.

Megamannen

@jay_s_uk I will double check, but I got a file with numbers in it, let me get back to you with a file

I got a file with numbers in v3.3, but it feels like it ends badly

Received mismatched data

@jay_s_uk
I think I identified the correct corner, it was easy to photograph for me. It's missing the diode, right?

jay_s_uk

@megamannen looks like it's missing. One for @Phaedrux or @dc42
When and where did you buy it?

Bought it at 2022-03-09 from your official reseller https://hobby-store.pl/

@megamannen is it a revision 1.1 tool board? If so then I'm sorry, it is indeed missing the diode, which provokes the error message when you run RRF 3.4 on it. Please email warranty@duet3d.com and include a link to this thread.

@dc42
Yeah, v1.1

No problem, you guys found the issue in no-time, will contact support
