4-14 Beambox II - Red Light Alignment

Description

This article will guide you through how to adjust the path of the red light to align with the laser path.

When to align the red light?

Tools

Please prepare the following tools.

Step 1

Please get familiar with how to make a pulse safely.

A. Turn on the machine. B. Close the lid. C. Enter Maintain mode and wait til the homing process is done.      (Make sure the door, back cover, and bottom icons are closed, or you won't be able to make a pulse.) D. Find the Pulse button. E. One press = one pulse, two presses = two pulses, and so on. ⚠︎ Please always make pulses when the door lid and back cover are closed.

Step 2

Use a screwdriver to unscrew the screws at the back of the machine, and the back cover can be opened afterward.

Step 3

Ensure the two screws on the sides of the red light emitter are tightened.

Step 4

Tighten the three adjusting screws on the red laser holder.

Step 5

Place a piece of "two-layer" tape on the first mirror and close the back cover to make 3 pulses.
(Do not remove the tape. Please leave it on the mirror.)

Step 6

Open the back cover and check if the burnt dot overlaps the red laser.

Good Example - Overlapped	Bad Example - Not Overlapped

Determine your result and the next action to take:

Step 7

We will now adjust the red light horizontally.

• Loosen the three screws at the bottom of the red light holder.
• Move the holder to make the burnt dot and the red light overlap horizontally.
• Tighten the screws.

Step 8

We will now adjust the red light vertically.

• Loosen the two screws at the side of the red light holder.
• Move the holder to make the burnt dot and the red light overlap vertically.
• Tighten the screws.

Step 9

Place a new two-layer tape on the first mirror and make three pulses to re-check the path.

Determine your result and the next action to take:

Step 10

Loosen the three screws to make them adjustable.

Step 11

This step checks if the paths of the red laser and the actual CO2 laser match and are aligned.
If they are not aligned, adjust the red light emitter with a 2.5mm Allen key.

Open the door. Place a two-layer, double-sided tape on the third mirror entrance. Enter the control mode and loosen the motor. Move the laser head to the bottom-right corner. Make sure the red laser is turned on. Close the door. Make 3 pulses. Check if the red laser dot and the burnt mark overlap. Adjust the red laser if necessary.

You may be able to find it on the second mirror and move the red dot to the reflective surface of the mirror.
