Tips on How to Connect stepper motors
Using the internal drivers The Duet 2 WiFi, Ethernet and Maestro all have 5 on board stepper drivers . To connect stepper motors to the internal drivers, refer to the wiring diagram at Duet 2 Wiring Diagrams or Duet 2 Maestro Wiring Diagram. The pinout of each stepper motor connector is the same as for other popular 3D printer electronics. Note: it is highly recommended that the stepper motor casings be grounded, especially in belt-driven printers. Otherwise, motion of the belts causes static charge to build up, which eventually arcs over to the windings. If the motors are screwed to a metal frame, grounding the frame is sufficient. Each hybrid step motor connector has four pins. You must connect the two wires for one phase of the stepper motor between the two pins at one end of the connector, and the wires for the other phase to the two pins at the other end. Identifying the stepper motor phases Here are two ways you can pair the stepper motor wires into phases: Use a ...
