Newbie Initial Wiring/Setup

[Rikk]

Hope you guys can help, I spent all day yesterday doing as much searching and research as I can so as not to have to post a help thread....but here it is ;(

Hopefully I've got all the info together needed, if not let me know what else is needed.

I have one axis setup at the moment (I have tried it with another stepper/driver/axis and it does the same), if I jog the axis in one direction it makes a slick clonk noise and moves VERY slightly (probably one step) then thats it, jogging in the other direction doesn't get any movement. The stepper does make a slight buzzing.humming noise when trying to jog in each direction.
The stepper is locked ie I can't turn it by hand.

I've stripped out mach3 and it's driver and reinstalled in case it was that but it's still the same.

Hopefully someone can point me in the right direction...pretty please ;)

Thanks
