3 Beam alignment
3.1 Laser beam alignment
Attention
: To do the laser pointer adjustment it is absolutely necessary to wear laser
protection glasses!
What you need
laser protection glasses (for
CO
2
lasers) part number 69300
the toolbox enclosed to the engraver
beam alignment tools (BAT) for mirrors #2 & #3
CAUTION
To make sure that there is no laser emission out of a controlled area
establish a limited access area by using non flamable beam blocking curtains,
temporary walls or other enclosures.
CAUTION
The laser beam alignment may only be performed by service
technichians that have been trained by Trotec and are familiar with the hazards from
lasers

Never expose any part of your body to the beam as this could result in serious
injuries.
CAUTION

glasses.
What you have to know
The number of the mirrors is counted from the outlet of the laser tube to the engraving head from
one to three.
The whole alignment is done while your machine is running. To make sure the system works at a
suitable power level change the test-pulse power in the Manager.
The laser beam is invisible. To find out its path, you use a BAT for
CO
2
lasers. It is burned at the
spot, where it is hit by the laser beam and shows a mark.
The tolerable displacement (distance from burned dot to the centre) is one sixth of the diameter of
the mirror or hole where you check the position.
