Measure your test square with calipers and get your exact kerf in seconds.
Cut a 100mm × 100mm square and measure it with calipers
Kerf is the material the laser removes. Without compensating for it, joints will be loose or won't fit at all.
Every time you change material, thickness, or adjust power and speed. Kerf changes with every combo.
| Material | Typical Kerf | Range |
|---|---|---|
| MDF 3mm | 0.15 – 0.20mm | CO2 40-80W |
| Plywood 3mm | 0.15 – 0.20mm | CO2 / Diode |
| Acrylic 3mm | 0.10 – 0.18mm | CO2 40-60W |
