I've looked and couldn't find any specifics (I know it's out there somewhere). I have a LMS 3960 with a CNC conversion completed and want to add spindle control. I use a G540 and mach 3... I know it's fairly simple, but need a wiring diagram. Any help? Can mach 3 also provide a tach readout? Will I need to add anything? If so whats needed/instructions?
Thanks in advance for any help!

Thanks daniellyall I'll look it over. That may answer my questions.
If anyone has actually made any of these mods to their LMS machine I sure appreciate it.
Thanks!
