Corrugated Cardboard 4mm

6 settings3 machines

This page lists 6 community-tested settings for Corrugated Cardboard 4mm. Paper cuts cleanly on both diode and CO₂ lasers - the key is high speed and low power to avoid charring and burning. Thinner paper (80gsm) needs less power than cardstock (200–300gsm). Air assist is usually not needed and can cause tearing on lightweight sheets.

Equivalent to ~70mm/s. Extrapolated from Noisebridge 100W chart (cardboard: 40% power / speed 1 in Epilog native units ≈ fast speed) and Boss Laser community. 100W easily cuts cardboard — keep power low to prevent scorching. Never leave unattended due to fire risk. Heavier chipboard needs 50–55% power.

Cardboard is flammable — watch for flare-ups. Air assist essential. Single-wall corrugated at 40% power cuts cleanly; chipboard or double-wall may need 50–60% power or 2 passes. Never leave unattended.

Laser cutting paper - what you need to know

Paper is one of the easiest materials to laser cut, but getting clean edges without charring takes the right balance of speed and power. The golden rule: go fast, go light. A 40W CO₂ laser cutting 80gsm copy paper might run at 120 mm/s and only 9% power - barely anything. Diode lasers need a bit more power but the same principle applies.

Paper vs cardstock laser settings

Lightweight copy paper (75–90gsm) needs the least power and highest speed. Medium cardstock (160–200gsm) can handle slightly more power. Heavy cardstock and chipboard (250–350gsm) may need 2 passes or a modest power increase. The settings in the table above cover this range across the most popular machines.

Tips for cleaner paper cuts

  • Turn off air assist - it blows lightweight paper off the bed
  • Use a honeycomb or pin bed to support the sheet flat
  • Tape the corners to prevent lifting mid-cut
  • For intricate designs, reduce speed by 10–15% and power by the same - this gives the laser more time to cut cleanly without burning
  • If you get consistent char on one side, check your lens focus
