Motor phase A and B may be disconnected reported from driver 2
-
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 1.22.6Second 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 :

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
-
Are there any markings on the Z motor to indicate its type?
Have you set up the deployprobe.g and retractprobe.g files for the BLTouch?
-
Hello,
Thanks a lot for giving me a hand.
On the motors it is written :
Anet Step motor
42SHDC3025-24BMy deployprobe.g reads as such :
; deployprobe.g
; called to deploy a physical Z probe

M280 P3 S10 I1 ; deploy BLTouchand my retractprobe.g :
; retractprobe.g
; called to retract a physical Z probe

M280 P3 S90 I1 ; retract BLTouchThanks once again for the help, I really appreciate it

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
-
Note that I have a genuine BLtouch classic if it might help you troubleshoot my problem
-
Funny thing, I was having these exact same issues the other day, but assumed I had 7 faulty motors as we were robbed the week before and they threw everything on the floor that they didn't want to steal.
Was also on the Z motors and my BL deploys, and then just stays there.
At least my motors have a bit of hope then. Been meaning to finish off the project. But need to redesign the X to move the hotend 20mm down so it can reach the bed.
Out of interest, did you perhaps try allocate E1 as a second Z motor driver aswell?
-
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
-
I measured the voltage going into the bltouch and it's 4.95v which I'm sure is okay. I'm really clueless now
-
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
-
Glad you got it sorted out! BLTouch wiring has given many people a headache.
-
Yeah but it is so easy with the tutorial. I can't believe my multimeter was the main culprit ahahah
