Accelerometer not found on specified port

[myersm1234]

Hello, As the title says I'm having issues with an accelerometer (Duet3D).

M955 P0 C"spi.cs6+spi.cs5" I61

Wiring connected to Duex5 Temp Daughter Board with no daughter board and supplied ribbon cable. I have tried different cables same length and shorter. Tried the 1k resistor. Short of making a USB3 cable ( I will do this tonight) I think I have crossed everything off the list I have found on this forum. I do get a green light on the accelerometer board. Any help will be appreciated

@myersm1234 can you post some photos of your installation?

[droftarts]

@myersm1234 Can you test whether it works on the Duet 2 WiFi temp_DB connector? Disconnect any temperature daughterboards and comment them out in config.g, connect the accelerometer, and send

M955 P0 C"spi.cs2+spi.cs1" I61

I have tried on the Duet 2 board but on top of the daughter board same deal not found. I will get some pics tonight.
Thanks for the help!

[myersm1234]

@jay_s_uk I will remove the board and try that also.

[myersm1234]

Here is what I have.
M115
FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 3.5.0-rc.3 ELECTRONICS: Duet WiFi 1.02 or later + DueX5v0.11 FIRMWARE_DATE: 2024-01-24 17:56:24

Tried on Duet 2 board with daughter board removed
M955 P0 C"spi.cs2+spi.cs1" I61 .
No Luck!

[myersm1234]

@jay_s_uk any thoughts on what might be my problem?

[jay_s_uk]

@myersm1234 did you disable the temp sensors in your config as well when trying without the temp daughterboard?

[myersm1234]

This post is deleted!

[myersm1234]

@jay_s_uk yes I did

[myersm1234]

@droftarts do you have any more suggestions ?

[droftarts]

@myersm1234 when you send M955 P0 C"spi.cs2+spi.cs1" I61 in the console, what does it actually report? And when you send M955 P0 after?

@myersm1234 Can you send M98 P"config.g" and post the response? This should run config.g and show any errors.

It may be worth trying with the ribbon cable between the Duet and Duex disconnected, too.

I should be getting a Duet3D accelerometer in the next couple of days, I'll set it up as you have and test.

Ian

[myersm1234]

@droftarts Thank you sir, I will get this done tomorrow night.

@myersm1234 I have replicated your setup on my bench, with a Duet 2 WiFi and Duex, using RRF 3.5.0-rc.3 and a copy of your config.g

I tested with the accelerometer plugged into the Duet directly first, then the Duex. I plugged in a PT100 board and a thermocouple board, and tested with the accelerometer in those, too, updating the accelerometer configuration in all positions:

As you can see, it was recognised when plugged in in all places! I was able to record motion profiles in the Input Shaping plugin in DWC and view them; these are the 'Error: Attempt to move motors when VIN is not in range' messages, as obviously I don't have any motors connected. I could wave the accelerometer around and it picked up the movement.

So I don't think this is a firmware or configuration issue, and looks like a hardware fault. I think the chances of both your Duet and Duex Temp_DB inputs failing is remote, especially as you have run temperature daughterboards in the past, and that either the cable or the accelerometer is faulty. If you have a multimeter, you could check the cable for continuity of each wire.

However, I think it would be best to swap your accelerometer for a new one. Where and when did you purchase it?
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 Thanks Ian, I really appreciate your help with this.
Thanks again! Mike

[myersm1234]

@droftarts Looks like I bought it at Spool3d on Oct.20/23, but just getting to install it now...lol. Probably not worth the effort for warranty, for the cost of a new one.

[droftarts]

@myersm1234 Up to you! But it would be good to get it back and find out why it's not working.
