budget diy cnc controller question

Download sheetcam, this converts DXF files into g-code which will run on mach3, then download mach3 demo license, at least you can see what it does when fed with g-code.

then you need a 2-d cad program to generate DXF files of what you want to cut, you don't mention plasma, router etc type of machine?

the motors really are the easy bit :)

if it's plasma, the HF interference will be your (and mine) major issue, read up on shielding, grounding etc
