Hi,
Thx for the reply,I have hooked my uc300 on to a Bob and from Bob to the transistor ckt. That u have given in the ckt diagram above.the only thing is that I made the ckt on a breadboard.as far as UB1 is concerned ,as Gerry said it only works with uc300eth whereas mine is uc300 usb.
Second thing is that I tried to run the stepper motor with the same connections (I.e pc( mach3) to uc300usb,to bob,from Bob to stepper drive) and it works well and the stepper motor runs smoothly.
But when it comes to driving a servo motor,it's not working.can u plz tell me if pulse and sign of the servo drive is to be given 24v signals as uc300 is a ttl device,and how to get 24v signals from a 5v Bob.can u suggest some circuitry.
Thx and regards
Jeetesh
