Automatic Sensor Calibration Jack c4 -Jack c5 -Jack c6-jack c7 front and back thread cut problem fixed, --- Summary You're able to automatically calibrate sensors, switch fabric types, set thick-material thresholds, and toggle short-thread mode, all via intuitive button combos. Successful operations are confirmed with OK on display (and sometimes voice prompts). If you need to further refine sensor responsiveness, you can explore the technician parameter settings (P66–P68) to fine-tune based on voltage values.
