12 bit spindle speed control with Mach3?
« on: November 01, 2012, 09:59:07 PM »
Hi All,

I am in the process of converting an old lathe that i have purchased to DSPMC/Mach3 control. I have noticed that rather than the typical 0-10V analouge speed control the controller for the spindle motor runs makes use of a 12-bit digital value to control the speed of the spindle...

I am thinking that i could use brains or write a plug-in to output the according 12 bit value over some of the output ports of my DSPMC controller.

Does this seem reasonable, does anyone know of a similar instance of this that they could refer me to or have any suggestions on the best way to tackle my problem?
