Jon's PWM DC amps come to mind: http://pico-systems.com/pwmservo.html You will need a hardware PWM generator, such as Jon's servo controller: http://pico-systems.com/univpwm.html Mesa also has similar solutions. http://mesanet.com/fpgacardinfo.html You will also need to close the feedback loop in LinuxCNC. I don't recall anyone using a tachometer signal with LinuxCNC, but I can't see that it would be too difficult. A quadrature encoder would also work. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/ ------------------------------------------------------------------------------ Get your SQL database under version control now!
