Yet another short to ground on driver (insert number here)
-
From looking through the forum whenever the message "Short to Ground on driver 4" then "over temperature reported by driver 4" comes up it looks like there is an issue with the driver.
After I had set up my Duet 2 Wifi's wifi (powered via usb on my computer) I then started plugging the components of my 3d printer in while unpowered. I started with the PSU, checked that it worked, then powered it off. I crimped all of my motor connectors, making sure the phases are paired correctly, tested, had one wrong, powered off, fixed it, then it worked. I then started adding all of my heater components and then the message saying "Short to Ground" popped up when I powered it on, which I find confusing for it to happen at this point. I unpower it, unplug all of my motors, power it on and it continues to show the error message. I then tried switching my motors around and it still showed the error message. This is where I came to the forum to see what was going on and I'm assuming is a broken driver. My 3 questions are, What motor is driver 4?, Why do you think it happened?, and Is this under warranty?
-
if driver 4 isn't the z axis is there a way to switch the failed driver to an open driver and block the messages from driver 4?
(update)
I looked into what motor uses what driver and driver 4 seems to be E1. This means that if I am able to block the errors i should theoretically be Ok to use it with the broken driver? -
@OgreCubes does the E1 driver get hot when the board is powered by VIN? It sounds like you have undertaken all the correct troubleshooting (checking that the error is still there with no motor plugged in. I assume you did not have a motor plugged into E1 anyway?
-
@T3P3Tony Correct, if I could just have the message stop appearing I could use the board without E1 the motor, I would be fine. I've only ever used the motor port when I was plugging things in (messed up and realized that I put a motor in the wrong port before powering) and testing to see what would stop the error message.
I also just tried to use the port to control a known to work motor and nothing happened, no significant temperature change, sound, or motion. When I did this same test with the E0 port the motor worked fine.

@ogrecubes Please contact who you bought the board from and ask for a warranty replacement.
Its not possibly to filter out just those specific warnings without hacking the firmware or web interface.

@T3P3Tony thank you for helping confirm my issue
