Getting Started
Welcome on your laser cutter journey. We at MAG Laboratory are proud to host the venerable and storied K40 laser cutter machine. As we should all know, each K40 machine is a unique snowflake upon this world not only because each factory K40 is manufactured differently but also because each K40 owner will apply different modifications to their machine.
Read at least the "General Use" section of the K40 user manual (link).
General Advice and Precautions
⚠ Always use the air assist.
⚠ Always operate with lid closed.
⚠ Do not let machine "run dry."
⚠ Do not place hand along laser path.
⚠ Ensure laser cooling water temperature is acceptable.
Software Support
The preferred file format is .svg. Inkscape (link) can be used to create and edit svg files it is under active development, so be sure to update your inkscape.
Materials
Recommended Materials
| Material | Comment |
|---|---|
| Acrylic | Cuts well. Turns into combustion byproducts immediately! |
| MDF | Mostly turns into smoke. Ash may be an issue. Use air assist to clear the ash. |
| Laser Rubber | Ash may be an issue. Use air assist to clear as much ash as possible. |
| Acetal Plastic | Apparently works if the plastic has additives. |
| Leather | Cuts / Engraves. |
Banned Materials
| Material | Comment |
|---|---|
| PVC | Combustion byproducts are literally hydrochloric gas. Do not cut. |
