@phaedrux Thank you!

Hi,

some time ago I bought 5 panel dues (directly from Duet3D, november 2021). One of them has a yellow line. I tried to reflash firmware but it didn't help.

@dc42 Thanks David for fast response and firmware. I've tested with v0.10 and v0.11 Duex and it works great.

@dc42 When will it be implemented? I've bought a few 0.10 and 0.11 duex boards recently. Now I have to manually change the config files for them. In the future it will also be a problem for maintenance.

Hi, I had similar issues.
Can you give me more information like duet version and firmware version? What browser do you use?

Next time when it occurs, let's check:

1. Try to ping your duet
2. Connect usb cable to your duet and get M122 log
3. Instead of reset you duet just plug again ethernet cable (it should reinit network)

@mackiez

Here you are my configuration files. I hope it will be working well.
I changed a bit extruder so XY maxima are bit smaller than normal.

tpre0.g tpost0.g tfree0.g stop.g sleep.g resume.g pause.g homez.g homey.g homex.g homeall.g config-override.g config.g bed.g

I also bought this board from Aliexpress and I wasn't able to run it. After investigation I realized that it is LIS3DSH chip which has different registers than LIS3DH.

AFAIK RRF3 doesn't support LIS3DSH right now.

Take a look on the chip. There is DSH instead of DH.

@robbe21 Ok, that's weird.
Can you post M122 anyway?

@robbe21
Did you try to replace endstop?

While homing Y axis try to put M122 in DWC console and put here output

@robbe21
Do you get any error/warning in DWC Console?

@robbe21 Hi!
We need your config.g and home#.g files

@alankilian
In M122 you have more precise information:

Stack: 0041f9c3 00459a3c 610f0200 3f800000 3d7df000 3edb6db7 b61cf800 49742404 3c3fdc9b 440739fd 40e190bc 0000bb9b 00000000 3e4fa932 41ddae4f 4e64e1c0 38533333 3f800000 3f800000 20000011 00000000 00000001 00000000 00000000 20002544 00000001 0041f9c3

Next step is download file with map file. You need to do it for your board and firmware version.
In your case it is this zip file https://github.com/Duet3D/RepRapFirmware/releases/download/3.2.2/Symbols-RepRapFirmware-Duet2.zip

There is .map file which include functions addresses in memory.
Then you need to compare your stack address and map file function address.

@flyingpig507
Hi!
Did you have similar issue before?
According to stack trace it looks like some sd card issue.
Let's replace this sd card.

@peta This path doesn't look good

@danielmar90

I think it is correct microcontroller.
Manufacturer number is ok, number of pins also.

@T3P3Tony Am I right?

@danielmar90
I'm from Poland so I can't help you but I thing there is someone who can

There is repair community so you can ask someone

@danielmar90

Hard to predict what happend but maybe some fan, heater short.
If you have warranty you don't need to worry but you need to wait for @Phaedrux.

If you don't have warranty you must replace microcontroller but it is very hard to do.

I can do it if you want but it depends which country you are.

@danielmar90

I have no idea what to do next.

@Phaedrux any ideas?

@danielmar90

It looks like microcontroller is dead.
AFAIK endstop diodes should be off after power up.
Heater E1 diode is also on (a bit).

Did you have a short?
I ask because maybe U11 chip is broken.

@danielmar90

In this method duet must have power supply from usb.

Can you take a picture? Try to make best quality.
