How do you catch joint-order mistakes before they become a first-motion problem on OpenArm?
A surprisingly common OpenArm problem is simple: the URDF, controller config, and hardware interface do not agree on joint naming or order.
How do you catch joint-order mistakes before they cause a scary motion on first enable?
Please share the checks you run for joint names, limits, sign conventions, and hardware-interface mapping.
If you reply, include one exact mismatch you have seen and one exact validation step that would have prevented it.
Visualization-only validation catches more than people expect, especially when naming and joint-axis assumptions drift between repos.
Slow single-joint enable tests are boring but they are cheaper than a full-axis surprise. Document the exact sequence once and reuse it.
If you have a pre-torque checklist or a config diff example, post it here. That kind of artifact becomes very searchable.
Pick your closest symptom to follow the right troubleshooting path.
Start with a reproducible symptom check for "[OpenArm] URDF joint order and controller mismatch for builders integrators (beginner)", then confirm host/service state before changing hardware or firmware.

python tools/preflight_check.py --quickAdd a simple preflight gate and a short startup checklist so regressions are caught before motion begins.
Use them as a checklist template first. Confirm interface names, fixture IDs, and safety conditions in your own cell before execution.
