How each score was set
Usability 7.0 /10
From published features and owner comments · not a lab test.
- Laser power and work area10.0/10
- 40W diode listed as laser power, apart from a 25V 11A supply rating; a 498 x 319 mm bed at 600 mm/s. Pass-through needs a separate feeder, so no bonus applied.
- Safety features7.0/10
- Four of five count: enclosed UL94-V0 cover, exhaust fans, named Class 1 with lid closed, and fire detection that triggers a CO2 set sold apart. An e-stop is described by reviewers but not on the seller page excerpt.
- Software and control7.0/10
- Free XCS software, LightBurn support, desktop and phone apps, and USB or Wi-Fi use without a subscription. No camera: the S1 positions by pin-point probe.
- Price and total cost5.0/10
- Price shown with free US shipping over $89, but the Basic Bundle carries a high compare-at figure; extras for safe use (Fire Safety Set, riser, extractor ducting, rotary) are separate.
- Warranty and support5.0/10
- 12-month main-parts warranty; 14 days free return then a 10-30% service fee to day 30, with return freight on the customer for non-defect cases; phone and chat with posted hours; reports on support are mixed.
