Pros & Cons
ComMarker B6 30W
What we like
- Deep engraving capability beyond 20W
- Cuts metal sheet up to 0.5mm in multiple passes
- Same autofocus and SpeedMax™ galvo as B6 20W
- LightBurn and EzCad2 compatible
- Compact at 13.5 kg
Watch out for
- Premium price vs B4 with similar work area
- USB-only (no Wi-Fi)
- No built-in enclosure
- Fiber laser only — cannot engrave clear materials or wood as cleanly as CO2/diode
xTool F1 Ultra 20W Fiber + Diode
What we like
- Dual galvo lasers: fiber for metals, diode for wood/acrylic/leather
- Exceptional 10,000 mm/s galvo speed for mass production
- 16MP smart camera for auto-tracing and precise placement
- Marks bare metal, stainless steel, gold, silver, and aluminum
- Compact and enclosed — safe for studio or office use
- Expandable to 220×500mm with optional conveyor
Watch out for
- Premium price (~$2,999+)
- Small 220×220mm base work area
- Cannot cut thick materials (galvo lasers excel at marking/engraving)
- Steep learning curve vs gantry lasers
