Building a Laser Cutter: Part 4 – Tests and Stability Improvements

The laser cutter is finally ready for testing! After securing the aluminium base plate (before that I had used carton) I powered up the system and sent my first gcode. Improving the Y Carriage Unfortunately, the lasered lines were rather wobbly. This was because the y carriage was only supported by one shaft. So, I ordered more parts. From Steplab:… Read More →

Apart from the music and general camping experience, one thing particularly got stuck in my mind: Someone wearing a beer crate as a backpack. While one could argue this not being an unusual sight at a music festival, the thing that impressed me as a maker were… Read More →

After completing the machnical construction of the laser cutter, it was time for the control circuit. I used a perfboard PSB and soldered headers for the Arduino and stepper motor drivers to it. On the bottom, I connected everything up. The limit switches needed some simple debouncing and smoothing on their signals, because the cables were so long and the… Read More →

Building a Laser Cutter: Part 2 – Mechanical Build

Because Actobotics parts are made and sold from USA, they are hard to come by in Europe (unless you want to pay high import taxes and shipping). In the end, I found an Italian shop (steplab.net / servocity.eu) which sold pretty much everything… Read More →

Building a Laser Cutter: Part 1 – Idea and Plan

Before I start, a word of warning: Lasers can be very dangerous to your health, eyes and general envoirement if misused. Please make… Read More →
