Nice! I built an older model MPCNC years ago, and was able to get pretty great results with it relative to the tiny cost and huge flex in the frame. I managed to cut some brass Christmas ornaments that I’m pretty proud of. I like that you’re using racks here - the belts on the MPCNC were a major weak point in my experience. I wonder if you could get away with 3D printed racks and pinions. There’s a lot of structural plastic in there already, would the hit from accuracy from using lesser racks make a difference?
