If there was an error during calibration, the following error message is displayed. Note that voltages may be different
depending on the system.
After the rotary wheel is pushed the following message will be displayed if the calibration was successful.
The parameters will vary slightly for each system.
The calibration will fail if the controller does not detect a change in voltage of at least 2.5 volt between the 1 mm and
the 10 mm positions. The default parameters will allow you to run the system but CHS position feedback will not be
accurate and the head will need to be positioned manually.
If the calibration feeler gauge is not available, you can use the nozzle extension adjustment (2 mm per rotation) to set the
nozzle to workpiece distance. To use this method:
1. Move the laser head down carefully until the nozzle is just touching the work piece.
2. Rotate the nozzle extension 1/2 turn to retract the nozzle 1 mm from the work piece. Use the menu on the
laser head controller to set the 1 mm calibration point.
3. Rotate the nozzle extension another 4-1/2 turns to set the distance to 10 mm and use the menu to set the 10
mm calibration point.
If the calibration fails, check the tightness of the nozzle adapter nut and the condition of the nozzle adapter insulating
washer. Repeat the calibration procedure as necessary and whenever the nozzle adapter is removed or replaced.
