@peter247 I cheated !
I soldered my mosfet on it, I wasn't able to melt the negative pad but I could surface solder it.
Right now I'm running my bed PID, everything seems in order.
Thanks a million time to both of you

@peter247 thanks for the idea ! I have two mosfets laying around my workshop. I'll do that for sure, it will protect the new terminal !
@phaedrux Okay thank you so much for the heads-up, my soldering iron is definitely not up to par so I will look for an other one.
I will update here once the terminal has been changed. I hope I'll be able to find an equivalent terminal locally
Thanks once again for all of your help, I really appreciate it
@phaedrux Okay, I was waiting to see if there was any way to have it RMA under warranty before touching it and potentially voiding the warranty if I had one.
I will see if I can find the terminal locally and will solder it back together.
I think it will work because with no wire inside the terminal I could see 12v. I guess tightening the terminal on the wires flexed it just enough so the burnt leg wouldn't contact with the trace anymore.
Thank you so much for your help, I appreciate it
@phaedrux Hello
This is a stock Anet A8 bed.
The Stock heated bed is 12V 1.2Ohm i.e. 10 Amp Peak Current.
When I measure it, I get 1.1ohm so the bed is not shorted or anything.
Also it is very weird that no fuse blew up when the terminal toasted. It feels like an early failure of the terminal
@phaedrux Yes Sir !
Here's pictures I just captured. Let me know if you need anything else
I used ferrules, see my heatbed wiring (keep in mind what you saw before was a brand new heatbed I just received)
Wire is there two wires, I have no idea, that how the bed came to me. My guess is that they tried to save money using smaller gauge wires but two of each. My old bed wasn't like that. I can provide picture of it if required. Even the doubled wires have ferrules :
The inside of the terminal looks good in my opinion :
Unfortunately, I though it was just a reflection but now with the flash it's clearly discoloured :
So I took the board out of the machine, and the negative lead crumbled to dust.
As far as I can see, it doesn't seem to have any damaged anywhere else.
Do you think it's something a soldering iron could fix or potentially the whole trace is burnt out ?
Thanks once again for your help, I appreciate it
@phaedrux Hello, thanks for the fast reply !
Here's the pictures. Talking about the terminal, I can't really see anything wrong with it, however it feels a little bit wiggly. It never occured to me to look behind the board to see if something is obvious
I will report back soon, when I remove the board
Hello all,
Something weird happened to me this week-end, I have a Duet 2 wifi
I was printing, when I came to check my print for the final hour, I realised the bed was 23 instead of 60. I found strange that the machine didn't stop but I could finish my print with no issue.
I used my multimeter and realised I had no 12v at the output for the bed. I immediately thought it was a fuse. I tested all of them and they're all good. On top of that, if I remove the fuse needed for the bed, the red light doesn't come on when I ask the printer to heat the bed.
I then changed my wiring and replaced my bed by a brand new one. I still have the same behavior.
As soon as I unconnect the bed, I have 12v on the bed output. When I plug the bed back, I end up with 0v
To me it feels like hardware failure but I hope I'm wrong.
Just in case you need it, here's my config, but I haven't touched anything since a while

Thanks so much in advance
Yeah but it is so easy with the tutorial. I can't believe my multimeter was the main culprit ahahah
Last post !
Found out my issue was completely stupid. I had a bad multimeter that showed continuity in my servo wire when there was none, it was broken
Now it works !
Thanks a lot for everything
I measured the voltage going into the bltouch and it's 4.95v which I'm sure is okay. I'm really clueless now
No I didn't try to reallocate anything. And honestly since now my Z axis is working I'm scared to touch anything, I'm just super glad I got this part working. I really hope I can get my bltouch working now so I can finally enjoy my shiny new board
Note that I have a genuine BLtouch classic if it might help you troubleshoot my problem
Okay what I did is wire both of my motors to the same connector (ZA) and instead of 500mA I put 1000mA.
Now my Z axis is moving. The only thing left is the BLtouch.
Now that I can home Z, I realise that it doesn't use my BLtouch for the homing, I pull and push the pin manually and it doesn't stop.
Thanks in advance for all the help
Hello,
Thanks a lot for giving me a hand.
On the motors it is written :
Anet Step motor
42SHDC3025-24B
My deployprobe.g reads as such :

Thanks once again for the help, I really appreciate it
EDIT : I tried to wire only one Z motor and put the jumpers in ZB connector. I still have the same error, I tried with both motor
Hello all,
I'm totally new here, I just got a Duet 2 Wifi yesterday.
I was so excited to set that up.
However I have at the moment two issues.
The first is "Motor phase A and phase B may be disconnected reported by driver 2"
I checked my crimps, tugged on my wires. Everything looks okay. I tried to swap the wires but I keep having the same error so I put them how it was wired originally on the Anet A8. I read on here that people seemed to have the same issue with an older firmware or with low current motor.
I have a Duet 2 Wifi 1.02 or later
Firmware 2.05.1
Wifi server version 1.23
Web interface version 1.22.6
Second thing. I wired a bltouch as per the wiki. I did my config with the configurator. I can't deploy or retract the bltouch at all.
Same thing here, checked my crimps and double checked my connections and my config. It seems all good.
Here is my config.g if it can help :
; Configuration file for Duet WiFi (firmware version 2.03)
; executed by the firmware on start-up
