Short to ground on drivers 0123

@Touchthebitum said in Short to ground on drivers 0123:

what do you need as info or tests ?

i suspect should repeat all the steps you did diagnosing the old board to see if the error persist when using the Duet as a stand alone board.

you could also configure your raspberry pi to be a wifi to ethernet bridge , but imho its easier to set a static up for a direct ethernet connection but all three options would work.

I have a connected laptop to my board but I don't know ho to connect

[dc42]

This is perplexing.

• Are there any other connectors in the leads that connect the motors to the Duet? If so, please post a photo of them.
• Please post a photo of the stepper motor wires where they go into the motor.
• Please use your multimeter to check that there is no continuity between any of the motor wires and the body of the motor.
• Use your multimeter to check that with the connectors fitted, the resistance across each phase is as expected (a few ohms, not a short circuit) and there is no continuity between the two motor phases. Your multimeter probes should be able to fit in the slots in the connector shells in order to make contact with the crimp pins inside.

to set a static IP address on the Duet, you have two options, config.g or USB. Both cases involves M552 S1 P192.168.1.14 as shown in https://duet3d.dozuki.com/Wiki/Gcode#Section_M552_Set_IP_address_enable_disable_network_interface

then you need to configure the correct network interface for the computer to use an address in the same network range. probably best to ask google how to do this for your operating system and version/language.

if you use the example above for the duet, set the PC to be IP address 192.168.1.15 with netmask 255.255.255.0 and leave the other settings blank or at their defaults.

if you have trouble with the computer let us know what operating system/version/language it is and maybe someone can help

• No, it is direct wire from motor to the board

• list item

• I checked 10x and there is no continuity, resistance is ok

• I tested the motors plugged with the multimeter and it is the same result like unplugged

• no short between motor case and plugs

Thanks, I used usb to make tests.

First test : psu on, no connected motors, no movements:

@Touchthebitum rather than using the PanelDue (try with it disconnected in case it’s causing the problem), send Gcode moves via USB. First set a position for the X and Y axis with G92 X0 Y0, then send G1 X10 F300. You will need motors connected to driver 0 and 1, or you’ll get an error.

Guide to setting up direct Ethernet connection here: https://duet3d.dozuki.com/Wiki/Setting_up_networking_on_Duet#Section_Wired_direct_connection

Edit: when the PanelDue is sending commands, they should be echoed on the USB (I think). If so, what command is being sent to move X?

@Touchthebitum, thanks for answering my previous questions. Two more:

• what is the stepper motor model number?
• what resistance do you measure across each phase?

[Touchthebitum]

@dc42

Motors are Blurolls 17HM19-2004S

I get 1.7 (stabilised) as resistance on every motor on both phase

I'll execute tests this morning

Hello
Same results with YAT and USB commands without connected Panel Due. Error short on driver 0 1 ...
I don't know what to say anymore....

@Touchthebitum please email me info@duet3d.com and I will arrange a return directly
