Mach doesn't send Pulses it sends "DATA". . .Has in Trajectory DATA to the Motion control Card which use's this DATA and does some Complex Maths with it to then create "PULSES" which it outputs to the drives at very high speed and with nice clear crisp signal. Whether that be Stepper or Servo drives or any device that expects Pulse signals.
Now if you want Closed Loop with Mach3 then you can have it.? . . . . But Mach can't do it internally, the Motion control card has to do it and there are very few that do and these come at a cost.
Electronic gearing in Servo drives are just Multipliers, they can only multiply what comes in and essentialy this comes from the encoder. So to give an overly simplified example say the lowest resolution your encoder can read equals 1mm and you have 4:1 gearing in the Drive then your lowest count or best resolution encoder can read now = 4mm. . . . So your speed increases but your resolution drops.!! . . . . . . Just has in life Everything that's free cost's something.!!Last edited by JAZZCNC; 07-01-2014 at 11:53 PM.
