Hi guys,
I want to build a Laser engraver that works using a sort of galvo system instead of the traditionally used linear actuators. Galvo systems are used in laser scanners to position the the laser point at high speeds (30.000 points per second) and high accuracy. Galvo systems start at 90$ on aliexpress but I find this a little to expensive for a proof of concept project. Additionally, the high speed characteristic of the galvo systems is not required for a laser engraver.
I would like to build a system which works similarly to a laser scanner but will be cheaper due to the compromise in the high speed characteristics. After some research of my own if come to 2 possible solutions (correct me if there are more/better ones). The first is to use stepper motors and the second is to use servo motors. I’m not sure which one will be the better and how good the result will then be. Gear boxes could be used to increase accuracy of the solution.
What are your opinions on the setup/project?
