[OpenArm] Motor ID conflicts after actuator replacement for builders integrators (intermediate)

How do you confirm OpenArm motor IDs are still correct after swapping an actuator so you do not discover the mapping problem during live motion?

Replacing one actuator on OpenArm can create a surprisingly bad failure mode: two motors answer like they own the same identity, or one joint disappears because the ID map is no longer trustworthy.

How are you diagnosing motor ID conflicts after actuator replacement on OpenArm?

Please share how you verify CAN IDs, update the mapping table, and confirm the final configuration before enabling full motion.

If you reply, include one exact conflict symptom and one exact validation step that prevented a second failure.

Comment 1

The strongest answers will say how the mapping was validated after the hardware change, not just how the hardware was installed.

Comment 2

If you do per-joint bringup or isolate one actuator at a time after swaps, share that sequence. It is extremely searchable.

Comment 3

A written ID map is boring but often the real fix. If a documentation step saved you, it belongs in this thread.

Quick FAQ

What is the fastest intermediate diagnosis flow?

Reproduce "[OpenArm] Motor ID conflicts after actuator replacement for builders integrators (intermediate)" in a controlled loop, then compare baseline vs current measurements before applying partial fixes.

python tools/reproduce_issue.py --case current_thread
python tools/validate_fix.py --checklist standard_intermediate
When should I stop patching and run full recovery?

If residuals or drift fail your acceptance limits after warmup, switch to full recalibration/recovery workflow.

Can I copy these commands as-is?

Use them as a checklist template first. Confirm interface names, fixture IDs, and safety conditions in your own cell before execution.
