Start of a new built.

If I never saw another piece of MDF I'd be happy, it bends just looking at it. If you must use wood then birch plywood would have been so much better.

I used plywood to build my first CNC and although I prefer ply to MDF, I would never use it again to built another one. Never had so many splinters in my fingers my whole life. LOL and it split in m ay places where I screw them together. I could have used different method to hold the pieces together but can do that with MDF as well to get a good connection.

Anyways, it don't hurt as much to mess up cutting MDF like this guy did, think I would have been a lot more upset if he buggered up the plywood. LOL

That sounds like far eastern ply, and I agree with you, but I'm talking about birch ply 18mm minimum.
