Best thing to do is wait for the 5th of november then BURN IT.:heehee:
The only place in CNC for MDF is to be used as spoil board.!! Even then I'm reluctant.

Seriously now you'll be far better of using Ali or steel the result will be machine massively more ridged and accurate and wont shape shift in front of your eyes every time you show it a cup of steamy coffee.!

Personally I'd go with steel due to it being far cheaper than profile. . . Don't have to be a welder and With just a few key tools like drill press etc it's very possible to build an accurate and repeatable machine. . . Welding will help speed the job up but Not required.

What sort of size cutting area and what material do you mainly want to cut.?

Edit: Opp's scrap that bit didn't see the 4x2 bit.
