Error: Short-to-ground on drivers 0 1

dc42

If you disconnect the X and Y stepper motors and command X and Y movements, do you get the same message, and do the driver chips get hot?

Gander

Good morning,
with disconected stepper motors i don´t get any mesage
without the fan i didn´t notice any temperature
i would say that the chips are a little bit warmer (2-3°)above environmental.
waited for 5minutes, is this long enough?

If the drivers don't get hot when you enable them (by commanding movement) with no motors connected, and you don't get the warning messages either, perhaps you really do have either a short between wires or a short to ground in the motor wiring.

Gander

seems legit, but
why does the z-motors with the z-cable work on the Z connector and doesn´t work on the X and Y connector?
the X and Y motors either work with their calbles on the Z Connector

Gander

i got other cables her, will crimp a plug on them and test again

dc42

Is there any sign of damage to the X or Y stepper driver chips, such as a round mark off-centre?

Gander

can´t see any damage.
but now it´s getting strange!
the new cable, only 15cm long 4 seperate wires so i can see that there is absolutely no connection to each other
Motor current is set to 800mA

This i tried on the Y-connector
trying the small nema 0,5A in my handworking, but doing verry strange movements
trying the one of the nema 1.7A (Z-axis), witch are build on the hypercube, the error comes again. That motor worked on the Z-axis connector without problems

This on the X-connector
now i plugged the Z-motor (giving an error on Y) on the X connector. working for 2seconds doing trange movements and then i had the error.
the small 0,5A nema working, but doing that strange movements

strange movements:
i would say he´s getting an right and left at the same time, so he doesn´t know what to do.

i wired everething like on this page
https://duet3d.com/wiki/Duet_WiFi_wiring_diagrams

first i thought, i have connected 2 wired wrong, so i turned the 2 A wires, the same movement of the motor

I think there must be a fault on your Duet, if the motors work OK when connected to the Z connector but not when connected to the X or the Y connector. Please ask your supplier to replace it.

here a picture of the wires connected to the motor

ok thanks for your help
have a great day
