How to Set Up Cardboard on the Atomstack A5 Pro 5W

1. 1Secure your cardboard flat on the work bed using clamps, magnets, or a honeycomb pin set to prevent movement during the job.
2. 2Set your focus distance accurately — use the auto-focus probe if your machine has one, or measure manually with the focus gauge.
3. 3Keep a fire extinguisher or spray bottle nearby. Cardboard is flammable — never leave the machine unattended while cutting this material.
4. 4Enable air assist if available. A steady stream of air at the cut point removes debris, reduces charring, and helps prevent flare-ups.
5. 5Enter the speed, power, and pass count from the settings table above into LightBurn. Use the “Cut” or “Engrave” layer settings panel.
6. 6Run a small test cut or engrave on a scrap piece of cardboard before committing to your final project piece. Adjust power up or down by 5–10% based on results.

What to Expect When Lasering Cardboard

Cardboard cuts quickly and cleanly at low power settings. Expect slight browning on the cut edges. Be vigilant about fire risk — cardboard can ignite easily if power is too high or the laser moves too slowly. Engraving on cardboard creates a subtle darkened impression that works well for packaging prototypes.

Common Mistakes to Avoid

• ✗Running at full power on the first attempt — always start with a test piece at the recommended settings and adjust incrementally. Going straight to maximum power risks burning through the material or causing fire.
• ✗Not accounting for the slower cutting speed of diode lasers compared to CO2. Diode lasers need multiple passes for thicker materials — be patient and let the machine do multiple passes rather than increasing power beyond recommended levels.
• ✗Leaving the machine unattended while cutting — cardboard is highly flammable and can ignite suddenly, especially at slower speeds or higher power settings.
• ✗Stacking multiple layers of cardboard to cut at once — this dramatically increases fire risk and produces uneven results.

Tips for Cardboard on Laser Machines

• ✓High speed and low power prevent scorching and flare-ups.
• ✓Single-wall corrugated is easiest -- double-wall may need multiple passes.
• ✓Air assist is critical to blow away flames and smoke.
• ✓Hold cardboard flat with magnets or weights to prevent warping during cutting.
• ✓Great for rapid prototyping before committing to wood or acrylic.
