A frequent SO-101 maintenance question is what happens after a servo swap: the arm powers on again, but nobody is fully confident the geometry and zero positions are still correct.
How are you recalibrating SO-101 after replacing a servo, especially in classrooms where the next user may not be the person who did the repair?
Please share how you verify zero position, safe first motion, and what minimum checks are required before the arm goes back into class use.
If you reply, include one exact post-replacement symptom and one exact calibration or validation step that solved it.
