Help with the Ethernet module of my Mini 5+
-
Hello again.
Yesterday I asked a question about my motors and managed to solve it.
But today I was doing work on my 3d printer and suddenly the Ethernet board stopped working entirely. There was no real reason this should have happened. I did no updated, but was changing some of the config files using the RRF config tool. I have now tried to check up via YAT the connection, but the serial seems to be dead as well. The RED 5V and green 3.3 V LEDs are on. But nothing else. -
When I power it with 24 V all four LEDs switch on. But not the red-blinking one.

@abindarraez1 work your way through this checklist, and report back what works and what doesn’t work: https://docs.duet3d.com/User_manual/Troubleshooting/Duet_wont_respond

@droftarts Thanks
I have done a full check and It is the status led. The one that is not switching on.
All power leds are working -
@abindarraez1 is it glowing? Most likely the firmware has been deleted. On the Mini 5+, a double click of the reset button should get it into USB mass storage mode. Then see https://docs.duet3d.com/en/User_manual/RepRapFirmware/Updating_firmware#duet-3-mini-5-wifiethernet
See further back up that page for firmware download.

@droftarts I can´t really see any glow. But I will try to manually install the software

@abindarraez1 The computer could never read the port.
Do you want me to try to erase the software with the jumper and use Bossa to reinstall the SW. I am not sure what to do next -
@abindarraez1 What were you doing when the board cut out? Could it be that you have shorted some wiring? Take a picture of your wiring, then it may be best to disconnect everything from the board, and see if that brings it back to life.
The Mini 5+ doesn't have a firmware delete jumper; double clicking the reset button is the mechanism to manually update the firmware.
If that doesn't help, post a good, clear, high resolution image of the top of the board, so we can look for damaged components.

@droftarts I was working with one of the end stop sensors. But I had left the printer separate. I turned to see my screen to see a failure in connection which set this issue off. Either ways. By Monday, I will try to get the pictures. I have a microscope in the house to get the best possible pics. (It will take me a couple of hours to get it out of storage.)

Quick update. I was checking out the board and there seems to be a bit of exposed copper plate. You will see it in the pic.

@droftarts Hello again. I was doing some testing on the board. And I noticed the Status Led Has a constant voltage of 0.44V through it in this state. Would this indicate a short circuit of some sort or A failure of the firmware?
I have tried with no success to get either a Linux or Windows computer to get to even recognize the board. They don´t seem to be able to read it. I try to reset it but it does not let me doit.
