CNC Rebuild?

So I’ve gotten to the point where I’m happy with the initial design of my CNC project but desire far greater accuracy. My humble rickety design just isn’t cutting it for repeatable, accurate creations [pun intended]. I’m contemplating creating a sturdier frame out of light/medium gauge steel. I have access to an arc welder and even a MIG welder. I suppose learning to weld together a sturdy steel frame will come in handy for future large scale robotic projects. 🙂
