Yes , MACH3 needs a certain amount of configuration before it is useful. To set it up you'll need to know the following:

  • pitch of leadscrews in mm
  • whether or not the steppers drive the leadscrews directly (you can assume they are 200step motors)
  • what type of stepper drivers you have
  • what breakout board (BOB) you have
  • how the BOB is wired to the stepper drivers...
Once you have this information, setting Mach3 up is relatively easy
