Short-to-ground reported by driver 1 2

[gabinnan]

I am using nema17 1.8° stepper on Duet2 Wifi. For the first try I got an error Short-to-ground reported by driver 1 2
Does it mean the board is damage? Please what should I do?

@gabinnan it means you need to check your wiring on the Y and Z drivers

[gabinnan]

@jay_s_uk still it says the same. My wiring with nema17 :

• Red to 2B
• Blue to 2A
• Green to 1A
• Black to 1B

what is wrong?

[jay_s_uk]

@gabinnan what is the stepper motor model?

Do the wires come directly out of the stepper motor, or is it a separate cable that plugs into the motor? If it's a separate cable then you can't trust the colours.

@jay_s_uk it think my wiring is right. I am using Nema 17HS16-2004S1.

It says the same error even the is no motor connected

[gabinnan]

@dc42 they are separated cables

[jay_s_uk]

@gabinnan can you post a photo of the end that goes into the motor?
Looking at the stepperonline page, they should be cables that come directly out of the motor, not with a separate plug.

@gabinnan can you therefore confirm the stepper phases using a multimeter, ignoring the colours of the wires. The link I gave you should guide you in that.

@jay_s_uk

red & blue same phase
black & green same phase

[gabinnan]

@jay_s_uk solution?

[jay_s_uk]

@gabinnan try a different driver and see if the error follows it.
if not, when was your duet purchased?

[gabinnan]

@jay_s_uk it is not working. it was purchase on june 14th 2021

[jay_s_uk]

@dc42 or @Phaedrux

[jay_s_uk]

@gabinnan also, where did you purchase it from?

[gabinnan]

It would seem likely that you have 2 failed drivers.
