Building a Laser Cutter: Part 3 – Electronics and Control

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…

Building a Laser Cutter: Part 2 – Mechanical Build

After designing my laser cutter, the next step was to order the parts and assemble the machine. 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)…

Building a Laser Cutter: Part 1 – Idea and Plan
