Perfect for my hobby desk!

Super safe and easy to get started. I used the mobile app to engrave some wooden coasters right out of the box. Great little machine.

Good but tiny

It's a fantastic engraver for the price, but the work area is very small. You have to be creative with it. Perfect for small tags and leather patches though.

FAQ

Can the Acmer K1 cut wood?

💡

The higher power modules (7W, 12W) can cut thin wood like 3mm basswood in a few passes, but the machine is primarily designed for engraving. The 2.5W and 3.5W modules are not suitable for cutting.

Is it safe to use indoors?

💡

Yes, its fully enclosed design and built-in fan with a filter make it significantly safer for indoor use than open-frame lasers. However, venting fumes to the outside is always recommended for safety.

Does it work with a Mac computer?

💡

Yes, the Acmer K1 is compatible with LightBurn software, which is a popular choice for laser control and runs on macOS, Windows, and Linux.

What materials can it engrave?

💡

It can engrave wood, bamboo, paper, leather, acrylic, anodized aluminum, and painted metals. It cannot engrave clear glass or bare metal without a marking spray.
