Great.

Thanks for all the help.

I contacted Syil and they had told me that they use a driver for the steppers and a controller.

The controller alows the programer to select the spindle speed from inside a g-code program and also the direction. They also allow for the use of a m code to turn on and off the collant.

Has anybody heard of this? What kind of controller is it?

Also what is the difference between steppers and servos? What is needed to make servos work?

Thanks
Pat
