Is my Duet board fried?

I just touched the duet board on the back of my running printer and all the lights went on, the motors did some strange noises and then shut down. Now it does not boot up and does not appear as USB device. I just wiggled a bit on one of the stepper motor cables to make sure it is connected.

I tried using the USB cable without luck so far. I pressed the flash erase and reset button couple of times but there is no USB device showing up. Is it dead? What can I do to check if it is still OK?

Damn it.

You can try to touch carefully the microchip. If it is hot then your board will be probably dead.

Turn off the printer (i.e. remove its 12V) and plug in a USB cable. If your PC does not recognise that any USB device (of any sort) is connected, you have unfortunately probably fried your board - probably something shorted the 12V rail to an input. The easiest way to check if a USB device has connected is to connect via a hub that has LEDs that light when a valid device is plugged in. If the LED lights, then the Duet CPU is still running in principle and there is hope.

Ok, I just unplugged every connection. and it works again. maybe something shorted out.

So you are lucky. The Duet could be damaged easily in case of a short circuit.

Hello Basti,
Hey Treito

I have the same problem. First the connection via www disconnected and then the connection via browser asked for a key, but I have not entered any key.
Then suddenly the RJ45 turned off. I tried launching Duet via USB and installed firmware again, but nothing happend.
I also tried to disconnect all plugs and my PC found connection via USB, but it was disconnected 2 minutes after.
The duet has no burn marks and jumper9 is connected. The LED near the micro USB glows.
I don't know what to do, can someone help?
If it's clear that the duet is broken, then maybe someone could link me a website where I can buy a new one for an affordable price.

The Firmware is "RepRapFirmware-1.09"
Arduino "arduino-1.6.1-windows"
Duet v0,6

Hi Bigbangnow

is there any part of the board that gets hot after you plug in the usb cable? What device is showing in windows? Maybe you have pressed the erase button and now you need to reflash the firmware?

Nope ,is not too hot, and i can see device in Windows, Ethernet is didnt work and any LED on RJ45 glows.


I bought new Duet, its work, but I have constantly 2 Error, and after 10 minutes connection via www disconnected and then the connection via browser asked for a key, but I have not entered any key.
