RE: [CAD_CAM_EDM_DRO] Re: Gecko Servo Drive Choice

Terry,

With your configuration you should be just fine with the G320. Just remember
to use steppermod not freqmod and crank your cycle_time parameters as low as
they can go and still let the system run. BTW, the difference between the 2
stepper modules is that freqmod was created to more evenly space the pulses
to the driver. The servo driver doesn't care how even they are so there is
no functional difference in this application between the 2 in regard to
accuracy and precision. But, the lower overhead of steppermod will allow you
to crank out more steps per second.

With the setup you are running you should be good to 180 ipm or more!
