3 Phase brushless motors

Hello List,
This is for some of the electronics minded folks. I have some small 3Phase
brushless motors and drivers I would like to use on a homebuilt engraver.
They have Hall effects embedded in the motors for feed back to the driver
chip , a TA7712. I have a PDF of the chip that shows how to monitor and set
the speed using passive components but think this is useless without proper
software. I was thinking that by using Turbo CNC I might be able to use them
by sending the signals directly into the power circuit. At this point all I
have is START, DIRECTION, and BRAKE signals to work with. These motors are
very powerful and high rev rates, so with proper reduction could work well.
Any thoughts would be appreciated. I have 2 sets of 3 for hacking up.
