Video: Building a tiny Arduino laser cutter

A Maker by the name of SilverJimmy may have already had a full-sized 50 watt laser cutter, but that didn’t stop him from wanting to design something smaller and microcontroller-driven.

Enter the MicroSlice, which HackADay’s John Marsh describes as an adorable little engraver.

“To keep the design simple, SilverJimmy opted for a fixed cutting table, which meant moving the cutting head and the X-Axis as a unit along the Y-Axis,” Marsh explained.

“The solution was to take inspiration from gantry cranes. He snagged a couple of stepper motors with threaded shafts, designed the parts in Inkscape, then fired up his full-size cutter to carve out the pieces.”

The MicroSlice’s bottom platform includes an Atmel-powered Arduino Uno (ATmega328) and the relays for the laser and fans, while two EasyDriver motor controllers sit above them on the next layer.
