Focusing

CAUTION

Risk of injury when working with mechanical components.

It is absolutely essential to maintain the correct focal distance for every laser marking process.

Only when in focus will the laser beam achieve the power density necessary for permanent

and clearly legible marking.

Prior to any marking it is therefore necessary to set the correct focal distance between the marking head and the

workpiece. An incorrect focal distance is the most common cause of poor or even indistinguishable markings.

Position the laser by moving the Z-axis until the ideal marking result has been reached.

The focal distance (A) is measured between the lower edge of the galvo head (B) and the upper surface of the

workpiece (C). The correct focal distance depends on the lens used (focal length).

Use the manual Z-Axis handle or the up and down buttons on the Keypad to move the marking head in

the correct position.

Positioning the workpiece

CAUTION

Risk of injury when working with mechanical components.

Use the “Border Mark” function in the marking software to indicate the marking field with the pilot laser.

Move the workpiece under the laser until it is in the correct marking position.
