Reference benchmark same job size on every machine so you can compare times fairly.

Laser spot size

0.154 × 0.121 mm

Smaller spot = finer detail (frame motion is usually the same across tiers)

Motion precision: 0.1 mm repositioning

Sample engrave job

~6–9 min

Filled photo or logo on birch plywood

10 × 10 cm (4 × 4 in)

Sample cut job

Pros

✓Massive work area for diode class
✓48W with Z-offset cutting in LightBurn
✓Auto-focus and TS1 offline control
✓Strong value vs CO₂ for large wood

Cons

✗Huge frame — needs dedicated table
✗15.2 kg machine weight

Beginner notes

Only buy if you regularly hit size limits on S30 Ultra or 400 mm machines. First laser buyers should start smaller.

Pro tips

Use Z-axis offset per pass in LightBurn for flatter thick cuts. Budget 50L+ air assist for claimed one-pass thick cuts.
