Second spindle

[Manuel S]

Hi, I have just set up a profile grinder, it works fine, but I would like to use a second spindle to rotate the part.
Now I am using a DC motor with manual speed control, but would like to control its speed with Mach3.
We are using the spindle output to control the grinding wheel, but is important for us to control the part speed.
Does somebody know a way to set up a second spindle and how to control it?
Thanks

Sounds like a job for a PLC, you need to ask POPPABEAR about that.
