I have two odrive S1 on a CAN chain , one of them suddenly started sending only heartbeat , does not respond to commands. I have tried re configuring but the problem persists.
Any ideas, this has been working for more than a year. I see no issues with usb.

Hmm, that’s quite interesting. Could it be a CAN busload issue? Or an issue with bus wiring or termination? Maybe a grounding issue?
There are two drives daisy chained on the same CAN bus, one is working perfectly the other is just sending heartbeat. I have tried switching the order in the daisy chain same issue. If it is a CAN bus issue
I would suspect that the heartbeat and the other drive would have a problem. The calibration process
works fine, the Botwheel rotates correctly.
I looking for suggestions to debug.
Could you send some pictures of your wiring? What are you using to send messages on the CAN bus? A USB-CAN adapter, or an Arduino, or something else?
I have attached a photo.
It is mounted upside down, it is driven by a Waveshare SN65HVD230 from a Jetson, driving
a BotWheel. again it was working , the CAN interface stopped working quite suddenly.
The ground is shared by everything, goes to the chassis.
I am expecting two S1s by mail, I will be happy to send this Unit for debug once I replace it with
one of the new ones. Please let me know if you would like me to do that, we are located in the
Bay Area, CA.
