Homemade Circuit Board and Software

I am just finishing up the layout of a 4-axis board.

It uses four ST Mico's L6208 stepper driver chip sets.
It takes from 8 to 52v and drives to 2.8A rms.
Each L6208 is connected to a single Motorola 68HC908MR16
microcontroller. You can control the clock, reset, CW/CCW, Half/Full
step and even microstep.

It also has a E-stop and 8 limit switch inputs.

The Parallel Port is also connected to the microcontroller.
With this configuration I can change or modify the I/O of the
parallel port to operate the stepper drivers. I was thinking of
using a USB port but heck that will be in my next version.

The serial port works a onboard in circuit programmer for the
microcontroller. All I need to do is flip a switch and reprogram the
microcontroller. I have designed the hardware to change its
operation in software.

With this nearing completion, I am now looking for software to run my
machine. I now have a three axis wood router.

I need to find software (I am willing to buy.) that will do the CAD
and CAM. Any suggestions? I need alot of flexability and complex
shapes.

This winter I will be designing a 4 axis machine. The fourth axis
will be a rotary axis that will turn a log 36 inch dia by 101 inch
long. This will be used to make wooden sculptures.
