Error: Short-to-ground on drivers 0 1
-
Hello,
i got a vew Problems with my Duet WIFI
Hardware:
Duet WIFI (firmware up to date)
Meanwell RSP500-24
Mosfet (only cause the breakout connector couldn´t handle the thick wires)
Nema 17 17HS4417 1.8° 1.7A
Nema 17 1.8° 0.5A (for testing)I´m trying to build a Core XY.
I have connected everething like in the wiki.
for the first tests, i´ve uploaded some existing configs from someone who build the same printer, just to have a basic setting.
then is tested the Z-axis, they are working, one turing the other direction, but that doesn´t matter so far, cause there is no load on the motors
after that i tried X and Y axis, more than a realy quick vibrating doesn´t come withe the Error: Short-to-ground on drivers 0 1
First i thought i connected something wrong, so i checked every wire and found nothing.
so i startet to asked unkle Google.
The only thing i found was this discussion about an broken board. There was something about the motor current, so i raised it from 800ma to 1600ma and tried again…
https://www.duet3d.com/forum/thread.php?id=2425#p22864
nothing
because i don´t know what to do, i´ve ripped of all the wires and connected them again in case there was a fault i didn´t notice, maybe…
but nothing, the same again.no i thougt hey what about a broken motor? new one, but shit may happen. so i tried the Z motors on the X and Y axis, the same Error.
The X and Y motors on Z are working.
Tried the other nema 17 with 0.5A the same.Because of all that, i think there couldn´t be something wrong in the wires and connectors, a broken motor is also impossible it only could be some settings, i don´t know, or i got a broken board.
So now i don´t know what to do, can annybody help me, or do i have to send the board back?
Thanks for your Help

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?
-
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.
-
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 -
i got other cables her, will crimp a plug on them and test again
-
Is there any sign of damage to the X or Y stepper driver chips, such as a round mark off-centre?
-
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 800mAThis 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 problemsThis 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 movementsstrange 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_diagramsfirst 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
