Using Mach3 with Win 7 and a Syil X4 mill. I am adding an automatic way oiler, but I only want it to operate when the spindle is running.
As I understand it, there is a spindle control circuit, and a spindle direction circuit. Can I use the spindle control line to control the oiler?
I'm guessing I would need a transistor/relay setup to convert the parallel port voltage to line current? Is there something readily available that I can purchase, or is there a different way to go about this? Mach3 is controlling the spindle speed...

I also like the idea of a "warmup" routine, where the machine travels to its limits and oils itself. Has anyone implemented anything like this?

Thank you,
Bryan
