Calibrate Capacitance

It is used to check the corresponding relationship of capacitance and position between the cutting head and the workpiece, so as to move Z-axis up and down in real time and ensure the relative distance between the cutting head and the workpiece is unchanged.

To calibrate capacitance, do the following:

1. To open Follow-up Control dialog box, do one of the following:

   • In the common tool bar, click .

   • In the menu bar, click System → Follow Control.

2. Select one of the following to move the cutting head to the position about 5mm far from the workpiece surface, and keep the workpiece still all the time:

   • If you have never calibrated capacitance, click the axis direction button.

   • If you have calibrated capacitance before, click .

3. To eliminate zero drift caused by velocity loop controlling, click . The cutting head slightly moves back and forth to compensate the error caused by zero drift.

4. Click .

The system starts to calibrate capacitance for 20s.
