    Hi Guru's out there

    I have purchased 4 x MB450A stepper drivers. They turned up with what I think is resistors (out of my comfort zone with electrics), 3 for each stepper driver.

    I sort of understand what they do but I do not have a clue how to wire them.

    Any help in basic terms would be a massive help.

    Cheers

    That's the "R" in the diagram and they go on the PLA-, DIR-, and ENA- wires that go back to the controller (according to the diagram). So you can either splice them in line or put one end into the associated screw terminals and solder the free end to the connection wire that goes to the controller.
