Friends have been asking about our K40 Chinese laser cutter. Here’s some quick info about our setup.
This is our current setup. The machine currently goes for $418 or less on Ebay. I don’t recommend buying the absolute cheapest one, and look for one with reviews. Shipping is generally free. It includes an highly inadequate exhaust fan, and a minimal water cooling pump and hoses. Out of the box, it works ok and requires installing the included, pirated copy of Corel Draw on a Windows machine. We used VirtualBox to “firewall” the software. Below the table is a bucket filled with distilled water and the aquarium pump, which pushes cooling water through the laser tube.
