Whilst some first rate lasers are out there for under $400 USD, they are inclined to be a minimal tiny. What if you wanted one thing a minimal nicer but didn’t want to leap to the $2,000 classification? The reply for [Owen Schafer] was to build it with areas he had lying close to and a several strategic purchases.
When he was to begin with organizing on using a diode laser, accomplishing just about anything additional than engraving is tricky. He acquired a low-cost 40 W CO2 laser tube, but it intended that he needed water cooling, mirrors, and extra complicated stuff that a diode doesn’t require. The frame is aluminum extrusion held together with 3D printed plates. Presented there was a powerful laser bouncing all over with mirrors, a plywood box fashioned the enclosure.
The stepper controller is an Arduino Mega functioning the Marlaser firmware, nevertheless [Owen] admits possibly a laser cutter-specific driver board would have been greater as he expended quite a few several hours trying to get the Arduino to do what he needed. Air air flow is a tube with a admirer that vents out a nearby window. H2o cooling is just a bucket of drinking water with a pump in it. A straightforward nylon hose connected to a compressor with a highest airflow valve delivers an air guide when reducing. Finally, we’re happy to report that [Owen] purchased protection eyeglasses unique to his laser to protect his eyes and investigated how to ground the superior voltages created.
We particularly beloved looking at all of [Owen’s] exam cuts. He proudly exhibited his containers, sharks, and lamp shades like any one with their new laser cutter is wont to do. If you are on the lookout to enhance your laser, there is an include-on for detecting elements optically or a fairly affordable laser bed you can throw in your laser.
