This laser calibration jig is specially designed for laser cutters where the laser nozzle height adjustment is done electronically using the operation panel’s Z+ and Z- buttons. For safety, the lid must be closed, which means that checking the correct height may require opening and closing the lid multiple times.

With this laser calibration jig, you can adjust the height of the laser nozzle while the lid remains closed and still see the height as you make adjustments.
