I wish to replace controller for

PROXXON - FF 500/BL-CNC
*
with a new system that will allow use of mach 3. The controller at the moment only supports NCCAD which is a nightmare to use with strange g code requirements. So wish to scrap controller and software.
What is the best off the shelf kit? It must have opto couplers to isolate pc. I have a uc100 parallel adaptor for mach 3 also.
Also mach 3 on laptop.
Put of touch and wondering if anyone can help with best places to buy or best hardware?

Any help, even if someone has a secondhand system that could be useful .
Sincerely Mark

If you already have a license for Mach3 you can still use that with a cheap USB-MACH3 controller on ebay for about $25 USD. Many of those controller do come with Opto couplers. The other advantage is you do not need a parallel port. If you are running newer windows from Windows 7 or newer this becomes a requirement. Windows 7 and newer will not support the parallel port driver from Mach3 and they will never release a newer version. You could use Windows 7 the 32-bit version if you want to use the parallel port.
