What is the phenomenon of not working that you mentioned? The capacitance value (C value in the bottom left corner of the homepage) on the HMI panel changes within the detection range: the C value increases when approaching the metal plate, decreases when moving away from the metal plate, and stabilizes when stationary. If the capacitance value does not change, check if the amplifier is well connected, if the internal wiring of the nozzle is normal, and if the metal plate is reliably in contact with GND. If there is a change in the capacitance value, capacitance calibration needs to be performed and the calibration results saved. When manually moving, if it touches the board and needs to rise a certain distance, the user parameter needs to check the collision alarm
