- Add MIN_PWM_PERCENT (20%) to ensure motor starts reliably - Add CURRENT_CALIBRATION factor (0.33) for accurate current readings - Add stall-based return option for pingpong mode (returns on stall instead of time) - Update stall detection: 7A threshold, 1000ms confirm time - Add DISABLE_STALL_DETECT config option - Keep last speed setting when motor stops (UI improvement) - Update webserver UI with 'Return on stall only' checkbox
