Rich M. was kind enough to donate a PC for the Sherline CNC lathe preloaded with Windows 10. I tried to download the necessary software today. Mach 4 would otherwise work fine on Windows 10. HOWEVER because we need to use the legacy parallel port plug in - it turns out that the plug in does NOT work on anything beyond Windows 7 or 8 and in 32 bit mode ONLY (ONLY!!!).
I have a clean purchased version of windows 7 which I can donate which means we may have to downgrade the PC to W7. I really hate to do that, but if we want it to work it’s what we have to do. Cost for Mach 4 is $200 and the plug-in will be $25. Of course, if we have to downgrade to W7 we might as well go with Mach 3 at a total of $175.
Cheers!
