Possible driver systems

  • Fixed motor and looped belt to carriage
  • Carriage mounted motor and fixed belt
  • fixed motor driving a leadscrew
  • fixed motor driving a ballscrew

Motors for each of the above could be one of the following

  • DC motor
  • stepper motor
  • brushless servo motor

What speed do we need?

  • for cut
  • for none cut moves
  • for etch/scan


How accurate do we need?
