@droftarts thanks a lot. I know the Zip download. Cool would be one button. I will look in the other options.

By the way, after changing the SD card to a new one, I did not face the issue anymore.

Thanks.

@jay_s_uk I think that solved the problem. It is much smoother now. But i will monitor it.

Thanks again for your help.

@droftarts thanks.

I could recover some of the files from the SD card via a recovery tool.

Got everything running again.

I will still check the SD slot tomorrow.

Is there anyway to backup all the data from the card, automatically or via a button in the DWC?

@Mike-0 It turns out the SD cad is not readable anymore.
when i send M501 via the a terminal software i recive the following message

SENDING:M501
Warning: Macro file config-override.g not found

I will try a new SD card tonight.

After i had a slight crash during a test with a new Bed.g file to probe 3 point of the print bed for a 3 motor Z axis. I pushed the emergency stop button in the DWC.

Since then i have no ethernet connection anymore. The led's do not flash on the Ethernet port on the duet2.

After pushing reset, i can now connect via usb cable and send commands and get an answer (to be fair i only tried M115)

But even after several on and off switching, the ethernet is still not connecting.

By the way i added in the end of the config.g a LED macro, which normally runs the led strip. But this is also not happening.

Is there any reset? Maybe the board is stuck in a loop?

@droftarts Funny enough, I used a 4th USB cable, and it worked. I have fixed the issue and it is running again.

@phaedrux @droftarts Thanks a lot.

@droftarts Thanks for your feedback

I tried 3 USB cable. The one in the video is just the last one I tried.

I thought that the firmware is on the chip and I also think it is running. I only changed the network settings. But that the com port is not working is rather strange.

Well, I do not find the Board in the network and also not on the router. I guess because is used the wrong IP address.

Flashing the Firmware would set everything back would be an option. But i not like to go down this road if it is not necessary.

I will try a new SD first.

Thanks again

@phaedrux Thanks a lot. I did that already, the LED's look fine.
But maybe you see something:

No, I did not try that. Is the firmware on the SD card or on the board ?
I will try to use an old backup of the SD card first.

Is there a manual for the Bossa procedure ?

I have a duet 2 in my E3d toolchanger. But now i face 2 issues.

1. The wifi does not work anymore !
2. If I connect the USB cable, i can not find a comport. 
   Everything was working fine until I tried to change the WIFI to an other network.

So I used:
M587 S"SSID" P"PASSWORD" I192.168.1.14 via the console in the DWC
But I used the wrong IP address. The IP address the Duet should use is 192.168.10.114. 
After restarting, I can not connect to the printer via WIFI so I tried a USB cable to connect. But I do not see the com port. I went through the documentation and checked the LED's, and they seem to work fine.  Whereby, the documentation tells me the WIFI LED should be blue and mine is Green, but I do not think that is the issue.

Now, is there any way to change the WIFI settings via the SD card. I tried to add the M587 S"SSID" P"PASSWORD" I192.168.10.114 to the config.g. But so far no luck.

Also, I do not find the reason why the USB connection does not work. I tried 2 Laptops, and it was working during the setup of the machine 9 months ago.  The Laptop does not find any usb connection. No Port, no unknown device, no error

@rjenkinsgb The load is not on the GPIO pin. It is on the 5V power supply of the GPIO pin bar, but I guess that power supply is also not strong enough. I did not come around to try it jet, connecting it to main 5V power supply.

I know I can still use the fan output. But I try to avoid it, because I might need them later.

@alankilian Thanks a lot for the link. I think that could the problem, I do not found any information how much high the current of the 5V output of the Duex GPIO pins is rated.

But as mentioned in your linked thread, I could try to grab 5V from the "main board".
Some People also used spare fan outputs. But I think the GPIO are the correct way of doing it, and in the future I might need the fan outputs.

Thanks again.
