Notable Features & Real‑world Insights
High‑Precision Spot: Excellent spot compression for detailed engraving (0.08 mm), consistent with advanced COS diode setups
Fast & Affordable: Offers rapid engraving at high speeds—presented at a competitive price point, reflecting broader-feeling “generic” lines of Chinese diode lasers .
Material Capabilities: Designed for wood, acrylic, leather, paper, sponge, plastic, bamboo, and stainless steel (mainly marking only) .
Assembly & Control: Semi-assembled, plug‑and‑play with diverse connection options (USB, app, Wi‑Fi, webpage control)
Best Practice: Many users recommend using LightBurn and adding air assist + honeycomb bed for cleaner results
Limitations: While capable of marking coated or stainless steel, the max won’t engrave raw metal deeply—diode lasers' wavelength limits apply
