Lots of details required to make a firm answer. How will the axis's be
driven? If you are using screws you get a lot of reduction and the motors
can be smaller to handle the cutting loads than if you are using rack and
pinion or direct belt drive (like on many printers).

I don't follow your comment that Gecko's or similar is not an option. Is
this just a budgetary constraint? I have built some of my own controllers
using the L297/298 chip sets and when it was done and said I probably had
$35 per axis in hard costs and I made my own board. If you add a commercial
board for about $20 or so a piece you are now at $55 per axis. I can sell
you a closeout original version Gecko G201 for not much more than that and
it will work right of the bat and you will not be limited to the 2 amps a
L297/298 setup is.
