The picture below shows the second mirror calibration.
10. The final step for calibration is to adjust the third mirror located on top of the laser
head. These adjustments are different from mirrors 1 and 2. This mirror is deflecting the
laser beam downwards to the material that is being cut or engraved. Therefore; the
adjustments are the opposite.
Place a piece of tape on the laser pen tip (nozzle) and press it against it to mark the
round tip. Send a pulse. The result will show the direction that needs to be adjusted.
