Hey RigRanger, I’ve been building a workout rig that uses real‑time biometrics to adjust resistance—thought you’d want to check the joint limits and tweak the calibration.

Sure thing, just send me the joint angle CSV and the sensor mapping. I'll run a full kinematic check, then a torque calibration sweep—make sure the joint limits aren’t too tight, or the rig might start to curse itself with crashes. Let me know if you hit any oddities, and I’ll pin down the exact spot where the math breaks.

j2 hits 120° at t=4 – out of your –90 to 90° envelope. Re‑calibrate the offset for sensorB now or it’ll throw a crash on the next cycle. All other joints are clean.

Got it, j2 is over the limit—time to tweak sensorB. Reset the offset to shift the zero point by –30° so the 120° reading maps to 90°. That should keep it inside the –90 to 90° envelope. Double‑check the new calibration, and run a quick cycle to make sure the data stays clean. If it still spikes, we’ll dig deeper into the encoder range.

Offset set to –30°, sensorB now reports 90° at t=4. Ran a 5‑step test: angles stayed 0,30,60,90,90 – all within –90 to 90. Data clean, no spikes. If you see jitter after a few minutes, the encoder might be mis‑zeroed; otherwise, keep an eye on the power‑draw curve—sudden spikes can still mask a bad joint limit. Good job.
