OPOS CALIBRATION (optional)
NORMAL CALIBRATION
The CALIBRATION OPOS sub-menu is used to calibrate the OPOS (Optical
positioning system).
This calibration is normally done in the factory. When the system is no longer
working precisely a calibration test must be performed. Calibration allows to fix
the exact distance between the knife tip and the sensor.
To calibrate the optical system, proceed as follows:
1. Power up the unit and load a piece of black vinyl with a white backing. The load
procedure is described in section 1.
2. Set the origin on a clean, blank part of the vinyl.
3. Press the
key (MENU) key until the message ‘INTERNAL TEST’ is displayed
on the LCD.

4. Press the
jogging key until the message ‘ CAL OPOS’ is displayed.

Press the
key to confirm the selection.
The cutter will now cut out a rectangle.
5. The message ‘WEED RECTANGLE’ will appear on the display:
