Lowcost capable CNC - Make vs Buy?

[JAZZCNC]

Thanks Andrew & Jazz for the very useful questions and answers, they have helped me to understand DIY CNC a lot better although my 'need' is for a smaller machine but one that will tackle steel.

If you want to cut steel and the parts will fit then buy a Milling machine is my advice. Building a machine to cut steel is at a different level to one for wood/aluminum.

The principles of the building process are the same but machine design, materials, and components are very different.
