Clamp angle_ before re-enabling servo output.
When saved limits shrink below the current angle_, update() can reclamp target_ and return without changing angle_. After release, ensureServoOutput() can then emit a PWM pulse for the stale, out-of-range angle_. The later clamp in writeAngle() is too late because output is enabled first.
Suggested fix
- const uint16_t pulse = angleToPulse(angle_);
+ angle_ = clampServoAngle(index_, angle_);
+ const uint16_t pulse = angleToPulse(angle_);📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Thanks for the careful work on centers, limits outside AP, and docs. Before we add more permanent calibration state, I want to check whether we’re matching the failure modes we actually see on the bench. Assembly procedure already centers at 90° before seating parts (docs/3d/assembly.md §2a, repeated per joint). §20 then sends people into the wizard mainly to mark safe min/max. It does not teach “set the real visual center first, then choose limits symmetrically around it,” and it doesn’t explain when animation zero should differ from If builders follow that procedure (center at attach, re-check center and tweak after assembly, set min/max as travel about that pose) center and midpoint stay the same by construction. In that world, persistent asymmetric servo_centers plus min→center→max mapping is a lot of settings/UI/firmware surface for a problem we might fix more cheaply by tightening the guide and a guided wizard, for example:
That keeps firmware mid as animation zero and avoids a second permanent calibration axis unless we have a clear bench case where safe stops are necessarily unequal distances from the true neutral even when the horn was seated correctly. On Ask: Are we solving “asymmetric safe band vs true neutral” as a common hardware reality, or “people skip 90° seating / set one-sided limits / mix Belly cables”? If the latter, I’d rather invest this energy in assembly §20 + a step-by-step wizard (and a channel smoke-test) than ship servo_centers + swap_hands as the default model. Happy to align either way... I just want complexity to track the real failure mode. |
What
After assembly, a joint's physical center can differ from the midpoint of its safe limits, and the two hand servos can be connected to opposite PCA9685 channels. Previously, the firmware always derived each center from min/max and range calibration was only available in setup AP mode.
servo_centers. Normalized poses map min → calibrated center → max, preserving each joint's endpoints. Missing or invalid saved centers fall back to the midpoint of the saved limits for compatibility.swap_handsin Config and the setup wizard to select left=2/right=3 or left=3/right=2. Apply the mapping after reboot to every PWM write, including setup moves and output release.Related to the calibration workflow introduced in #25.
Compatibility: existing HTTP routes, pin assignments, NVS keys, and stock servo ranges are unchanged. This adds settings and permits saving existing range fields outside setup AP.
