CAN Bus Woes on S1

1

I cant seem to get any CAN communications out of the S1 Module. Im not quite sure what I am missing…it might be the ground star , but not sure if I need it. Current setup is as follows

Power Brick to Jetson Orin.
Jetson Orin
ODRIVE USB can module via USB cable.
CAN/USB resistor switched to on. (Tried off too…)
JST cable (from odrive usb can module) to JST connector on the ODRIVE S1
S1 Power by wall brick, with power and ground going into terminals.

I can configure and run the S1 via web interface via USB on a separate laptop.
When monitoring the CAN messages on the web interface inspector tab, there is no activity.
I can see the hal tick increment so I know the web interface is working.

Drivers for the CAN interface loaded properly on the Jetson ORIN, but I can not see any messages via candump or cansniffer.

Is there a CAN bus on button or something I am missing?

Hi! Can you post a picture or sketch of your wiring? Do you have the CAN-USB GND connected (either directly or through the S1’s CAN daisy-chain header) to DC- at a single star point? What commands on the Orin have you used to set up the USB-CAN adapter?

This is my current wiring setup. No usb from ODRIVE to Jetson. It is configured via web gui from a different computer (CAN enabled). I am not sending any startup scripts to the ODRIVE…I assumed can bus would just load automatically on bootup and I could use can to communicate with it ?

Additionally, the wall wart I am using is only 2 prong now that I think about it. The laptop supply is 3 prong to the wall
