Our take on the OMTech K40+ 45W Desktop CO2 Laser Engraver with 8" x 12" Working Area and Detachable Honeycomb Workbed

The OMTech K40+ is a desktop CO2 laser engraver with a 45W tube and an 8" x 12" working area. It ships with a detachable honeycomb workbed, which makes it easier to cut through thin materials and to clean up debris than a fixed-bed K40. It runs on the bundled LaserDRW software and does not include LightBurn. It suits hobbyists and small shops that want an entry-level CO2 cutter and engraver for wood, acrylic and leather, and it is smaller and lighter than most 50W and 60W desktop units. Owners rate it well, though the K40 family is known for needing setup and alignment work out of the box.

About the OMTech K40+ 45W Desktop CO2 Laser Engraver with 8" x 12" Working Area and Detachable Honeycomb Workbed

This is a compact desktop CO2 laser engraver with an 8" x 12" (200 x 300 mm) engraving area. It is sized to sit on a workbench and is meant for small craft projects. It has an integrated power supply and an upgraded X/Y rail gantry system with a high-precision stepper motor.

An LCD control board sets the laser power. Two temperature displays show the laser power supply temperature and the cooling water temperature. A red dot pointer on the laser head shows engraving points, marks the machine's path and indicates positioning sizes to help with project setup.

The work surface has a stabilizer clamp for irregular-shaped objects and a vented level board for regular-shaped ones. Removing the vented level board adds 2" of Z-depth for taller materials. LaserDRW software is included. LightBurn software is not.
