[Orca Hand] Tendon routing and finger symmetry for builders researchers (beginner)
Orca Hand discussion on tendon routing, finger symmetry, cable tension balance, and basic assembly checks for stable motion.
A lot of early Orca Hand frustration comes from small tendon-routing mistakes or uneven finger symmetry that only shows up once the hand starts moving under load.
What assembly checks help you catch tension imbalance before you start debugging software that is not actually the problem?
Please share how you verify tendon routing, finger return behavior, cable tension, and whether one finger lags or overtravels.
If you reply, include one exact mechanical symptom and one exact adjustment that improved symmetry.
This is one of those threads where a photo checklist or tension checklist can save the next builder hours.
If one finger behaves differently, note whether the issue was tendon path, friction, preload, or joint alignment.
Practical assembly heuristics are welcome here. Searchers often want the first three checks, not a theory lecture.
