I'm from Germany.

So you think it could be possible to repair the board.

I will defintly check everythink before powering up.

A okay but that W5500 seems to be really hard to replace. So I guess I have to purchase a new one.

Would you recommend me to buy the Duet 2 Wifi. Because there are acctual fuses on it?

Hello,

sorry I was on vacation, so I couldn't work on it.

I replaced the SD Card and structured the folders like on the documentation written.

If I run the M552 Code I see following:

M552
Network is enabled, configured IP address: 0.0.0.0, actual IP address: 0.0.0.0
ok

But with M552 S0 i cann't disable the network adress. There are no LEDs flashing when I connect an Ethernet Cable. I just looked closer to the W5500 and it looks like that there is a crack in the chip.

Hello,

so if I connect the Maestro via USB to my computer I find the COM port in YAT. I can also type in the M-commands. M39 is giving me the capacity of the SD-Card and M503 shows me the firmware. With M552 I can set the Ethernet but if I connect the Ethernet cable nothing happens. I can't start up the webserver. That's what I mean with I can't boot it up.

Hello @dc42

I just tried to just hook up 12V and ground. Like you said the three LEDs light up. I also bought a new SD Card. The Controll finds it but I wasn't able to Boot up yet.

Best regards

Hello thanks for the quick reply.

Everything looks fine. I was sure when I read something about the blown up MOSFET it must be this part because the smoke was close to the Port. But after checking I think the MOSFET is still okay.

The wiring should be okay. There is just a possibality that something was wrong with one endswitch wire or the positiv heatbed wire, because that came lose while changing the side of the printer. But I soldered it back on the Heat Bed before reconnecting to the board and powering it up.

My system runs on 12V.

Tomorrow I will get a new small Micro SD Card and will look if the board is booting with it.

Hello,

after purchasing the Duet Maestro I connected everything to my printer and did the first test prints. Everything was looking alright. I decided to change the controll to the other side of my printer and hooked up all cables again. As soon as I powered it up all LEDs were lighting up. After a few moments I realized something was wrong but in that moment something made a "puff" sound and some smoke was coming out close to the VIN. I don't know the exact part. I guess I was a little bit to slow with the Emergency button.

So the result is that the SD-Card got corrupted and nothing is working anymore. I can connect through the YAT but can't really change any settings. I testet the MOSFET and it seems to be alright. I can't see any damage to the board (like the square thing with U3 looks fine) and when I connect USB the three LED's (5V 3.3V and the red LED) light up.

Is there a way to fix my board?

It would be really depresing if I killed it one day after ariving.

Thanks in advance
