[OpenArm] CAN bus timeouts and recovery for builders integrators (intermediate)
#1 OpenArm teams often hit intermittent CAN bus timeouts after a bringup change, a motor swap, or a long teleop session.
What is your fastest recovery workflow when joints stop responding but power and cabling still look normal?
Please share concrete steps: interface reset order, watchdog handling, bus-load checks, and how you confirm the arm is safe to re-enable.
If you reply, include one exact timeout symptom and one exact recovery step that reduced repeat failures.
#3 One practical pattern is to document the exact reset order for interface, drivers, and controllers so new teammates do not improvise during recovery.
#4 If you have a safe replay procedure after a timeout, share it. That is often more valuable than a one-off fix.
The most useful replies here will separate transport issues from controller-state issues. Include the first log line that told you where to look.
