[Orca Hand] Tendon routing and finger symmetry for builders researchers (beginner)

What mechanical checks help you catch Orca Hand tendon-routing issues before you waste time debugging the wrong software layer?

Post

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.

Comment 1

Mechanical asymmetry hides well until you compare fingers side by side with the same motion and preload. Builders should post that comparison explicitly.

Comment 2

If a finger returns slower than the others, capture whether the cause was friction, routing, or tension. That distinction matters for everyone who searches later.

Comment 3

A photo-based checklist or cable-preload note is especially useful here because assembly threads are often more reusable than code-only answers.
