3D Printed DC Motor Laser Galvo

I am trying to figure out of Marlin has any galvo support for my metal printer project. I found a cheap supplier of f-theta lenses and mirrors. If I can wing it I am going to spend a few hundred bucks on setting one up. Then I will stick the entire thing in a vacuum chamber and cross my fingers. My end goal is a metal 3D printer kit for 3 or 4K.
