The dspmc controller does not "convert step/dir" to analogue. The motor/servo setup does not rely upon the clock cycle of Mach3 step pulses.

What are you meaning by "the clock cycle of Mach" ?
I do not know exactly the form of the information the plugin gets from Mach but Mach plans the trajectory and sends the info to the plugin and the DSPMC controls the motor in relation to these commands.
Thanks for the replys
The costs mount up verry fast in the servo area.
$500 pluss just for the boards , I dont realy see why they have to be so much more than large stepper systems.
If you have servo drives that can natively accept step/dir signals then there is no need for external controllers, if you have analogue only drives then there is.
