GalvoStep

Project for building a cheap galvo laser system using Stepper motors and widely available parts. The main goal is to engrave pictures onto wood much faster than a XY-machine could.

This repo contains mechanical and electrical diagrams, firmware and extensive documentation of this project to maximize accessibility. Feel free to copy/advance this project.

For a documentation of the supported G-code commands see the wiki.

Final Update 20.03.2021

GalvoStep V1 is finished. See https://youtu.be/tV-LJvpVcUo for a typical engraving process. Accuracy is +-0.5mm I'd say. All the software can be found in CODES.

UPDATE 04.01.2021:

GalvoStep V1 is now functional but requires further testing. See https://youtu.be/xkFyk6ncNaY for initial test. GUI (.py and .exe) and the Firmware for Teensy 4.0 can be found in CODES

UPDATE 11.10.2020:

The prototype report is done. See Documentation. GalvoStep V0 (proof-of-concept) is finished. Now onto V1! (Goal: Actually engraving pictures)

UPDATE 01.10.2020:

First prototype is now functional! https://www.youtube.com/watch?v=stV5wWasxEc
