Get this alarm while the machine is not working

• Check if the capacitance will change to 0 when touching the nozzle by hand or a conductor such as a screw driver, shown as below. If it will, then you should calibrate the height control system, and the issue should be resolved. Otherwise,

• Remove the nozzle, and check if the capacitance will change to 0 when touching the metal part of the ceramic ring by hand or a conductor, shown as below. If it will, then you should clean the nozzle, install it back and test again. If there’s still the same issue, then replace the nozzle with a new one. Otherwise,

• Remove the ceramic ring, and check if the capacitance will change to 0 when touching the pin of the sensor body by hand or a conductor, shown as below. If it will, then you should replace the ceramic ring with a new one. Otherwise,

• Check if the capacitance will change to 0 when touching the terminal of the wire by hand or a conductor, shown as below. If it will, then you should replace the sensor body with a new one. Otherwise, please replace the wire with a new one.

Get this alarm while processing

• Make sure the material is processed without protecting film.
• Set the laser head follow a piece of material, then turn on assistant gas blowing. Check if the capacitance has a big change (>100). If it will, then you should check if all the parts on the sensor are fixed tightly (including the sensor body, the ceramic ring, and the nozzle). Otherwise,
• Check if the laser is aligned and can come out from the center of the nozzle. If not, then you should align the laser. Otherwise,
• Check if the capacitance has a big change (>100) while processing without laser firing (only the laser head moves along the cutting path). If it will, then you should check if all the parts on the sensor are fixed tightly, and they will not move from each other while the laser head is moving. Otherwise, please contact us for further support.
