The K40 laser cutter is an affordable and versatile machine that works with a range of materials. It features a CO2 laser tube and a cutting bed with an area of around 300 x 200 mm, allowing you to cut or engrave a variety of items.
The best K40 laser cutters have a good motion system that allows for smooth and accurate cutting and engraving. These systems usually use either smooth linear rods or linear rails to control the movement of the gantry.
Using an analog current meter is an essential tool for controlling the power of your CO2 laser tube and optimizing the machine's performance to its maximum potential. They are available in your local hardware store and will make it much easier to fine-tune the power for any material you choose to cut.
Air Assist:
One of the most important upgrades you can make to yourk40 laser cutter is an air assist system, which consists of an air pump and a nozzle that blows out a steady stream of compressed air to prevent flare-ups. This feature not only improves the cutting quality of your engraver, but it also helps prevent smoke particulates from getting into the lens and reflecting mirrors.
Rotary Attachment:
If you plan to engrave or cut cylindrical objects like cups, bottles, and glasses, it's a good idea to look for a K40 laser cutter with a rotary attachment. These rotary attachments can be installed on top of the cutting bed and come with two rolling pins that support round workpieces.
