Re: [CAD_CAM_EDM_DRO] Re: Servo driver circuits???

Ballendo,

Im with you on this one, you would think that it was possible, in particular
since a suitable circuit could be cut out with a stepper cnc rig, even my
small home built one will do that if some one has the G-code or just a
circuit diagram, i could create the G code from that.

Here is a link to the quasar site ref the servo controllers

I dont know is this is more to do with RC servos though :-(
