Before you write
- The order number and the exact model and power (for example a 30W vs a 60W kit).
- A photo of the machine showing the issue.
- The job it failed on — material, speed, and any accessory used.
Who is responsible
ComMarker's official product pages say “All products are covered by a warranty service.” The warranty period is not stated on the official pages we checked on November 12, 2026 (PST), so we don't state one. We haven't tested the products; confirm warranty terms with ComMarker or the seller before you buy.
Warranty and returns belong to the seller on your receipt. The channel comparison explains the difference.
Safety first
These are Class 1 or Class 4 lasers. Stop if a shield is cracked, an interlock fails, or the beam path is not as the manual describes. Use eye protection and ventilation appropriate to the material.
