    I’m no expert but I have never connected the enable pins to anything as my understanding is that giving them 5V tells the driver to halt (reverse of what you migh expect).
    If this is the case then remove the 5V cable to en+ and any cable on en-
    Hopefully someone more knowledgeable can confirm this

    I don't have any limit switches or e stops attached at the moment . I have taken it all apart to try and work out what is going on . all I have is 1 driver 1 stepper the powersuply and the bob. I get 3.7v on the input side of the bob on pins 2 when I jog left I get 0v on pin 2 when I jog right . but all the output pins read 5.1v dc . nothing changes on any of the out put pins . if I connect the stepper there is no movement. I can feel it get hard to move and a small buzzing but no movement when I jog.
