Even though some decent lasers are out there for less than $400 USD, they are likely to be a little tiny. What if you preferred some thing a very little nicer but didn’t want to leap to the $2,000 class? The response for [Owen Schafer] was to establish it with sections he had lying all around and a several strategic purchases.
Though he was initially arranging on employing a diode laser, carrying out anything a lot more than engraving is tough. He procured a low-cost 40 W CO2 laser tube, but it meant that he desired h2o cooling, mirrors, and much more complicated things that a diode doesn’t have to have. The body is aluminum extrusion held together with 3D printed plates. Presented there was a powerful laser bouncing close to with mirrors, a plywood box shaped the enclosure.
The stepper controller is an Arduino Mega running the Marlaser firmware, even though [Owen] admits potentially a laser cutter-precise driver board would have been improved as he put in many hours hoping to get the Arduino to do what he desired. Air ventilation is a tube with a admirer that vents out a nearby window. H2o cooling is just a bucket of h2o with a pump in it. A straightforward nylon hose connected to a compressor with a greatest airflow valve provides an air guide while slicing. Eventually, we’re satisfied to report that [Owen] purchased basic safety glasses specific to his laser to shield his eyes and investigated how to ground the substantial voltages created.
We especially beloved seeing all of [Owen’s] check cuts. He proudly exhibited his bins, sharks, and lamp shades like any one with their new laser cutter is wont to do. If you are wanting to up grade your laser, there is an add-on for detecting products optically or a comparatively cheap laser mattress you can toss in your laser.
