BEAM ALIGNMENT
:
After getting your machine up and running you may need to do a beam alignment. This will
ensure you are getting a good cut and that you are utilizing the full power of your laser. There
are five parts to the laser path. Laser to rear mirror, rear mirror to gantry mirror, gantry to head
mirror, head mirror to focus lens and focus lens to the piece you are working on. We will be
focusing on the rear mirror to gantry mirror and the gantry to head mirror. Please watch the beam

1.
Remove the side panel, the panel to the right of the laser cabinet when looking from the
front. You will find the laser to rear mirror and the rear mirror to gantry mirror. In your
accessories box you will find 1x1in square acrylic blocks. These will be used to align
2.
Take one of the acrylic blocks and apply double sided tape to one side. You will attach
this block to the rear mirror to gantry mirror. Go to the front of the machine and press the
pulse button on the control panel for one second. You will see a small circle etched into
the acrylic block. The circle should be in the center of the mirror, if it is not you will
adjust the laser to rear mirror. The mirror will have three knobs for adjustment, turn them
according to the position you need the laser to strike.
3.
Once the laser to rear mirror is properly adjusted you will then move to the gantry mirror
to head mirror. You will remove the first acrylic block and reposition a new one to the
gantry to head mirror and repeat the process until satisfied with the adjustments.
4.
At this point you can use paper tape and apply it to the tip of the laser head. If the beam
does not create a circular hole directly in the middle of the tape you will need to adjust
the focal lens using the screws on the top of the focal lens.
