I was recently lucky enough to get a fully-CNC ready Sherline mill, in the form of a Paxton Patterson CNC training machine. This was used in middle or high schools for training vo-tech students in how to run CNC.
Unfortunately, I can't seem to get it to talk with my PC. It's running software called Millmaster Pro. Inside the box, there's a PC board labelled OptiDriver Plus that has a parallel port which I've connected to the PC. This is labelled "Controller" on the enclosure. It also has a DB9 connector labelled "Robotic Interface". I have no idea what to do with that. I am running Windows 95 in DOS mode (booting to a floppy made from Win95's command.com and the rest).
I'm hoping to find someone who might be able to help me troubleshoot what's going on. I have been able to fix a couple of electrical problems with the box, and for all I know, there are more.
Thanks, Bob
