i'm planning on converting an X1 from harbor freight to CNC
i got most of the stuff nailed down but the only thing i havent figured out is which stepper motors to use ... in terms of torque ...
especially for the Z movement ... i assume that guy needs a bit of power to be able to move the entire motor-spindle assembly up/down ...

any lead are welcome. if anyone can give me mopdela nad typenumbers they used and work OK ( and where they got em )
and possibly what driver board they use them with.
