You don't need to make a new control system. Mach3 software will do what you want.
ArtSoft USA - Home of Mach3 and LazyCam
But you will need to add a breakout board, and maybe new stepper drivers, so that the lathe can connect to the parallel port.
But there is an easier way.
where can i find the existing software which can control SpectraLIGHT 0400 Turning Center? |
The Spectralight was made by Intellitek.

Email Intellitek. They are nice people. They have been very helpful to me when I was working on one of their mills.
They can give you the software, and can probably sell you a new interface card. That is easier than converting the lathe to use Mach3.
Good luck!
