I have a Variable frequency driver for my spindle motor. It is capable of varying the speed of the motor based on variable voltage sensing circuit. As the input voltage varies from 0 - 10vdc the spindle motor will speed up or slow down accordingly. Can the SmoothieBoard supply this variable voltage on ouput pins based on the G-Code spindle speed?
Summary:What types of VFD can be used with the SmoothieBoard?
