Mach3 and VFD Wiring

[dcrowder]

For a bit more money the Mach3 Controllers on eBay look a better option! I also use a 4th axis slaved to my Y so the Arduino sounds like it'll fall short of my needs.

Regardless of having no automatic speed control setting - last night I fired my baby up with it's spindle for the first time and it made it's virgin cut!

Ok first let me just clear you up on something.? Mach3 is the controller, or more correctly the Control software. BOB's are just a distribution device and control nothing. There only purpose is to make wire connections easier and in some cases offer protection to the PC.
Higher spec'd Bob's offer extra options like having built in Relays or Speed control but again they Control Nothing. They just only provide the means mach3 does all the controlling.

Also Mach3 while being the Controller doesn't make any decision on what spindle speed or feed rate to use. It just does what you tell it. Either thru G-code or manual commands and buttons or sliders on screen.

So these controllers on Ebay are more likely just BOB with few bells n whistles. Show use.?
