Duet Maestro no Ethernet lights and no light on endstop switches
-
Ok, disconnected everything and removed the sd card. The only thing connected in the power from the power supply. The part in the red circle looks fine, I don't see anything out of the ordinary. I do have a green LED for the one you have circled in green. I also have a red led lite below that and a blue LED below that. I connected the ethernet cable and still get no activity LEDS. I checked the voltage to the board and it is a solid 24 VDC.
When I connect the USB cable, I get a red LED next to the USB plug, the green 3.3v and red 5v. But I don't get windows finding the board and no open port to access it.
Here is the pic with the USB cable connected.

if you're positive the USB cable is a fully functional data cable (as opposed to charging only cable) then at this point you've got nothing to loose by fitting a jumper on the two pins labeled ERASE and seeing if the red LED on the other side of the USB port also light up. LED labeled DIAG.

@bearer ok, I switched out USB cables and got it to connect to the computer, but I still have no ethernet activity. I can not access the board through pronterface.

is this over usb/serial or ethernet?
if the board connects to the computer what does the device manager show it as?
-
it is over serial, the computer shows it as USB serial device(comm 3)
-
the serial device is either the duet reprapfirmware or the bossa bootloader - doesn't it show a more specific name than usb serial?
-
No, it doesn't but, I ran a m551 s1 and the ethernet came back online. I am not sure why it would have gotten turned off. I guess I will turn it off and hook all the wires back up and see what the web interface shows.
-
ok, I found the problem, there was a short on my y axis endstop. I guess when I remounted it, I had the screen go in to far and it touched the circuit on the back of the endstop and was shorting out the 5v. Feel kind of dumb, but glad my board is ok, thanks for all of your help.

Yep, the screw went across of three traces, this could have been very bad.

Glad you figured it out.
