Quick answer: Open or remove the front/rear passthrough panels, level the honeycomb table with the body frame, manually focus the laser head, secure your material, then bypass the door safety interlocks and run the job.

Applies to: Thunder Laser Titan and Titan Pro series  |  You'll need: 2.5 mm Allen wrench (for rear panel), magnets or pinning devices, optional external support stands

Titan machine overview

What is the passthrough used for?

The passthrough allows oversized objects to fit in the machine. Your Thunder Titan has a flip-down front door and a rear removable slot. Material can hang outside the machine on either side while being processed.

⚠ Material will protrude outside the machine during cutting or engraving. Do not allow the laser head or gantry to collide with protruding material. Use pinning devices to keep material flat and external supports to balance the weight of heavy pieces.

The passthrough door height is approximately 70 mm. It supports materials with a maximum thickness of approximately 65 mm.

Step 1 — Open the front passthrough door

Locate the front passthrough door on your machine.

Step 2 — Remove the rear panel (if needed)

If you do not need to push material through the rear passthrough, you can leave the rear panel installed.

To remove it: use a 2.5 mm Allen wrench to remove the screws holding the rear passthrough panel. Remove the panel and store it safely.

Step 3 — Position the honeycomb table and secure your material

Set the honeycomb table to be level with the body frame.

  • Thin materials: Place flat on the honeycomb table and secure with magnets or fixed tools.
  • Longer or thicker materials: Place flat on the honeycomb table and use external stands for support if necessary.

Step 4 — Safety and exhaust considerations

⚠ Removing the passthrough panels exposes the laser beam path. Read and follow all laser safety guidelines before proceeding.
  • The top cover of Titan series machines is made of standard transparent tempered glass, which effectively blocks laser radiation emitted by the laser source.
  • The top cover of Titan Pro series machines includes an additional yellow-green protective panel compared to the Titan series, which effectively blocks laser radiation emitted by both RF and Fiber laser sources.

Exhaust performance will be reduced with panels removed, and residual smoke and smells may escape into the room. Only run with passthrough panels removed when necessary.

Step 5 — Run the job

  1. Place the material flat on the honeycomb table and secure it. If needed, use shelves or stands in front and behind the machine to support the long material sheet and keep it flat.
  2. Download the job file to the machine. Set Origin, Focus, and Frame as needed.
  3. Bypass the door safety interlocks manually. By doing this, you accept all the risk and results of running the machine in its altered state.

  4. Press the Start button to begin the job.
