When some respectable lasers are out there for underneath USD 400, they are likely to be a minimal smaller. What if you desired a thing a minimal nicer but didn’t want to soar to the USD 2000 class? The reply for [Owen Schafer] was to build it with components he had lying all-around and a number of strategic buys.
Whilst he was at first preparing on working with a diode laser, performing anything far more than engraving is tricky. He ordered a low-cost 40W CO2 laser tube, but it meant that he wanted h2o cooling, mirrors, and extra sophisticated things that a diode doesn’t need. The frame is aluminum extrusion held alongside one another with 3d printed plates. Provided there was a strong laser bouncing all around with mirrors, a plywood box formed the enclosure. The stepper controller is an Arduino Mega working the Marlaser firmware. Even so, [Owen] admits most likely a laser cutter-certain driver board would have been greater as he used many hrs attempting to get the Arduino to do what he wanted. Air ventilation is a tube with a admirer that vents out a nearby window. Drinking water cooling is just a bucket of drinking water with a pump in it. A simple nylon hose linked to an air compressor with a highest airflow valve presents an air help while slicing. Last but not least, we’re pleased to report that [Owen] acquired safety eyeglasses certain to his laser to protect his eyes and investigated how to ground the significant voltages generated.
We specifically loved seeing all of [Owen’s] check cuts. He proudly displayed his bins, sharks, and lamp shades like any person with their new laser cutter is wont to do. If you’re looking to enhance your laser, there is an insert-on for detecting materials optically or a fairly inexpensive laser mattress you can toss in your laser.
Movie just after the split.
