my thought is if he goes to aluminum extruded rails and wheels sliding along those rails then he is just like 105462 other make your own CNC machines out there, for the same price as they are.
i like the design of this. the locally sourced parts, the option to print my own.
I doubt i would have made this if i just bought a kit with parts, etc for $500 and built it.
maybe thats just me 🙂
