    I've got myself a uccnc hd bb2 bob that has rj45 connectors. Balazs at uccnc explained that the axis connections are as follows

    HDBB2 RJ45 pin 1. step --- Drive Pul+
    HDBB2 RJ45 pin 2. dir --- Drive Dir+
    HDBB2 RJ45 pin 3. gnd --- Drive Pul-
    HDBB2 RJ45 pin 3. gnd --- Drive Dir-

    I will be wiring to 3 leadshine em705 digital drivers. Would I be correct in assuming that I could link DIR- and PULSE- on the stepper itself ? Or is there a better way to wire the drivers with this BOB ?
    Cheers

    Andrew
