RE: [CAD_CAM_EDM_DRO] Homegrown servo motor driver?

Hi Dave,

As you're probably using a microprocessor, I'd check the manufacture's demo
software and application notes.

MicroChip and Atmel have some good application notes as well.

Check on the Baldor web site for some application notes on motion control:
