help needed with my set up

[amxen]

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.
