Accelerometer not found.

@droftarts Doh I didnt see the firmware requirement I believe im on 3.45 so ill update it now thanks.

@droftarts Sadly that didnt work same error message.

@Festivejelly As it has no shroud, check that you plugged the ribbon cable into the Temperature Daughterboard connector the correct way around. See the Duet 2 WiFi wiring diagram here: https://docs.duet3d.com/Duet3D_hardware/Duet_2_family/Duet_2_WiFi_Ethernet_Hardware_Overview#wiring-diagram

Post a picture of both ends if you're not sure.

@droftarts as oriented on the diagram you linked I have the cable plugged in where the red wire appears to be on the bottom left. Which would match up with the pin diagram on the board with the red wire being pin 1. I'll take a picture to illustrate but im sure that the wiring is correct. Im suspecting a duff unit tbh as there are no LED's lighting up on it.

@Festivejelly Try it the other way around anyway. If no lights are coming on, it's not getting power, QED it's the wrong way around!

@droftarts Tried it both ways, even tried it on the duetx5 expansion board. Nothing. I think the sensor is just dead out of the box. Waiting for a generic LIS3DH to come and ill try wire that in instead.

Festivejelly

So I just connected a generic accelerometer and it works fine. Sot he duet one was basically dead from the store. I got it from oozenest I guess I need to contact them for a return?

Festivejelly

Got a "new" duet accelerometer from Oozenest.. version 0.2 (which i think is actually the old version) dead too. No LED nothing (with the provided cable) but yet I can plug in a generic accelerometer and it works and detects it fine.

That's quite strange. Can you send some photos of your setup?

Festivejelly

@Phaedrux Will do ill take some later. Its an e3d tool changer and im plugging it into the main board with the supplied cable. As I said before I managed to get a no brand accelerometer to work by using the same supplied duet 3d cable then just branching off some duponts. But when I try to plug either duet 3d accelerometer into the cable nothing happens no lights, and a message saying it cannot find the accelerometer

Ill take some pics and upload them later.

@Festivejelly you need to be running 3.5RC1 (I think) or later for the new accelerometer too

Hello all, I am having the same issue. I have done everything above. I have a green light thought. Tried it on both Duet 2 wifi and Duex 5. I've also tried a 1k resistor, different cable same length and shorter about 12" and still not found.

@myersm1234 Best to start a new thread for your issue.

myersm1234

Will do. Thanks

@Festivejelly Can you confirm what firmware version you are using? Please send M115 in the console and paste the response. If you are still on 3.4.5, neither a v0.2 nor v1.0 accelerometer will work. Thought the lack of green power LED does indicate it's not getting power.

@Festivejelly Can you have a look at the tests I posted here https://forum.duet3d.com/post/337624, and see if it helps? Otherwise, I think a(nother) warranty replacement is in order.

If so, please send an email to warranty@duet3d.com and CC your reseller. Include a link to this forum thread and the details of your original purchase. You'll receive a reply with a form to fill out.

@droftarts Its 3.4.6 i notice 3.5 was release today so ill upgrade to that to see if that helps. Ill also try your tests.

droftarts

@Festivejelly Have you made any progress on getting your accelerometer connected? Do you have a PanelDue connected? If so, are you using both cables (ie ribbon and 4-wire)? @myersm1234 found in his thread https://forum.duet3d.com/topic/35460/accelerometer-not-found-on-specified-port/33 that disconnecting the PanelDue ribbon cable fixed it for him, though I was not able to replicate the problem in my bench setup.
