Which is best and why, for build a low cost Cnc? ($$$)
Which is best and why, for build most complete Cnc? (spindle ctrl, limit switch, coulant, e-stop... )



Where I can find MCU MSP430 Code sampler for ctrl Axis ?

The pic 18F series is the minimum you should use from microchip. A pic,12 and 16 are close to the same price and why bother ? They support the 18F with a good C compiler and it has much better power.

The 297/298 is so old and not even mosfet. They run hot and rough and have been around since the 80's. Use a newer chip from Allegro, check their site.
