Help with a Short to Ground that is occurring
-
Hi, I just bought a Duet 5 mini + Ethernet. Then a Ground to Short occurred so I asked for a board change and got it again. I really don't want to have to send this board back as well. So I connected it and tried to move it, but a ground-to-short error occurred again. I just checked each motor and the Mechanism (The printer is a delta) moved with a simple DRV8825. Is there some config I am missing?
The current is .850 Amps.
Also, please indicate to me if I should change the driver. I will buy the spare and get it soldered here.
Thanks -

@abindarraez1 which driver is reporting a short to ground?
-
@jay_s_uk 1Generally Driver 1. It also sends me a high temp alert.
Driver 2 also sends me an error. -
@abindarraez1 if you swap the motor on driver 1 with say driver 0, does it report the error?
Owns various duet boards and is the main wiki maintainer for the Teamgloomy LPC/STM32 port of RRF. Assume I'm running whatever the latest beta/stable build is
-
@jay_s_uk I am worried it might burn that driver as well
But I will try it. -
@jay_s_uk Error moved. Now it is on driver 2 and 3. Also, the printer moved but with a lot vibrations.
-
@abindarraez1 so you have a problem with your stepper motors and/or motor wiring. Nothing wrong with the board
-
@jay_s_uk Thanks a lot. But any clue what could be causing it? The motors seem to work well with the DRV8825
-
@abindarraez1 poor or failing crimps would be my guess
-
@abindarraez1 Thanks, I will revise them.
