Replacing the Auto Focus Pin

Steps

1. Place a cloth under the laser head, resting on the blades. This will catch any pieces that may fall.

   

2. Using a 2mm Allen key, loosen the set screw on the autofocus assembly. Do not remove the screw.

   

3. Unscrew the autofocus sensor pin, and carefully remove it.

   

   📌 Note: Be careful not to let the red flag piece fall from the autofocus assembly. If it does, simply return it to the assembly, with the hole positioned inside the assembly.

   

4. While holding the red flag piece in place with one hand, screw the new autofocus pin into place.

   

5. Using a 2mm Allen key, tighten the set screw on the autofocus assembly. Do not over-tighten.

   

   📌 Note: Do not over-tighten the set screw. Turn it slowly until it is snug, then unscrew it by 1/4 of a turn.

6. Press the plunger up with your finger to ensure that it moves smoothly up and down.

   

7. To ensure that the pin is seated correctly, power on the machine and watch that the red light turns on.
