There are plenty of controllers out there, you can get a 4 axis cnc controller with lots of I/O and inbuilt PLC for about £1500-£2000.
It does not need to be the same as the one allready in the machine.
You could also use a galil PCI card, but how much would that cost? then the cost of the PC, and does the galil card accept the linear scales? I am not familiar with gallil stuff, but i do know that there is a plugin for mach.
