Warning! 

• Wear safety goggles during the entire aligning process.
• Avoid attaching the tape directly to any of the mirrors.
• 8 mA or 11% should be sufficient to leave a clear mark without setting the testing tape on fire.
• Always make sure the path is clear between the laser and its target. Never allow foreign objects between the laser and its target. Always close the cover before firing the laser. Do not look directly at the active laser through the cover during this procedure.

Having a perfectly aligned laser path is paramount to your engraver’s overall performance. Each K40+ goes through a complete beam alignment before shipping. You should, however, inspect the alignment yourself upon arrival and about weekly during normal operation. Refer to the diagram below for the basics of the alignment.

Tools Needed: Masking Tape

Laser Tube Alignment:

The laser tube emits the laser beam, which bounces off Mirror 1. Follow the steps below to check the laser hits Mirror 1 right in the center.

Step 1: Put on safety goggles and open the rear access door to expose the laser tube and Mirror 1 as shown.

Step 2: Attach a piece of masking tape to the mirror’s frame.

Step 3: Turn on the machine and set the power level to 11% or lower.

Step 4: Close the cover.

Step 5: Fire the laser.

Step 6: Check that the burnt hole on the tape is at its center.

If the mark is off-centered:

Step 7: Cut the power to your laser.

Step 8: Carefully adjust the laser tube in its brackets by loosening its bolts.

The part indicated by the green arrows: Bracket

Warning!

• Be careful not to over-loosen or overtighten the bolts. Only adjust one stand at a time.
• Use rubber shims to elevate or remove the existing shim. This will lower the laser’s position on the bracket.
• Once the laser tube’s elevation is adjusted, you will need to check the alignment of Mirrors 1, 2, and 3.

Step 9: When adjusting the tube is completed, repeat steps 2–8 until the burnt hole falls perfectly at the center of the tape.
