Fiber Laser Alignment – Maker / Edge / Pro

Fiber laser alignment is a crucial maintenance procedure to ensure the optimal performance of your Fusion Edge and Fusion Pro laser engravers. Over time, misalignment can occur due to regular use, component replacement, or moving the machine to a new location. This guide provides a step-by-step process for checking and adjusting the laser alignment, helping to maintain consistent engraving quality, maximize laser efficiency, and extend the lifespan of critical optical components. Following these instructions will help prevent weak laser power, ineffective cutting, and premature failure of lens assembly optics.

Fiber Laser Alignment

Fiber laser alignment should be checked periodically to ensure that the engraver is operating at optimum performance. Complete this procedure if any of the following behaviors are observed:

• Laser power appears weak in certain areas of the table.
• Engraver is unable to effectively cut through materials at recommended settings.
• Optics in the lens assembly fail prematurely.
• The engraver has been moved to a new location.

Fiber Laser Safety

• Do not fire the fiber laser with any engraver panels removed.
• Do not place any part of your body in the beam path while the laser is in operation.
• Do not defeat the safety interlock system in the engraver.
• Prescription, Lexan, and polycarbonate eyewear will NOT protect your eyes from the fiber laser.

Fiber Laser Red Dot Pointer

In fiber-only equipped engravers, it is not necessary to align the red dot pointer to the laser beam. This is done internally by the manufacturer and cannot be adjusted in the field.

Marking Laser Alignment

Table Positions

There are four (4) mirrors in the Fusion Pro Fiber which may need adjustment during alignment.

Mirror Locations & Corresponding Table Position

• Near Field Mirror – Position 1 & 2
  
• Far Field Mirror – Position 4
  
• Mirror 3 – Position 3
  
• Mirror 4 – Perpendicularity of Laser
  

Adjusting Near Field Mirror (Position 1)

1. Place masking tape on the alignment target over the window optic.
2. Activate the red dot pointer.
3. Move the lens carriage to the top-left corner (position 1).
4. Check if the red dot is centered on the alignment target.
5. Remove the left side panel.
6. Adjust the red dot position using the three Allen adjustment screws.
   
   

Adjusting Mirror 3 (Position 3)

1. Activate the red dot pointer.
2. Move the lens carriage to the top-right corner (position 3).
3. Check if the red dot is centered on the alignment target.
4. Adjust mirror 3 using the three Allen adjustment screws.
   
   

5. Verify alignment by moving between positions 1, 3, and 4.

   Note: In some cases, this process can take several back and forth movements between positions 1, 4, and 3. Ensure that the correct mirror is being adjusted for each position.

Perpendicular Alignment

This process ensures that the vector cut is as close to 90 degrees as possible.

1. Activate the red dot pointer.
2. Raise the table using the Focus menu.
3. Remove the alignment target from the lens carriage and place it on the table.
4. Lower the table by 3-4” (75mm – 100mm).
5. If the red dot is not centered, adjust mirror 4.
   
   
6. Raise the table and verify the red dot does not shift.
