Even accepting the above, you would still need to redesign the machine (possibly modify the chassis) and add mirrors/optics. The Z-axis would be required to focus the beam by moving the lens up/down.
Yes, Mach3 would work - it can switch the laser using one of the outputs and adjust power with PWM or an analog voltage convertor.
Zax.
