My machine is P2 33W+ infrared laser module
For custom jewelry engravers, precision is non-negotiable. The ACMER P2+A2 IR laser's 0.03mm spot size puts my ols machine to shame - I engraved a 2cm-long silver pendent with fine text, and every letter was crystal clear. Last week, I used its tarnish removal function on a vintage metal sign, and it looks brand new. I unboxed it at 2 PM, set up the Lightburn in 10 minutes and started engraving. I finished three orders before dinner.
