A pal of mine has cobbled together a stepper motor, motor drive controller PWM generator (MKS OSC) & st-4045-a1 stepper motor driver. He can make it go back and forth but he's unable to make it brake or freewheel.
From some things I've seen, it appears (based on my probably incorrect interpretation of a Chinglish write up) that the enable/disable function has three states +5v for enable, 0v for freewheel & -5v for brake. The fleabay item number (293499193226) is the PWM controller. This link is for the controller
Has anyone any idea a: if my theory is correct and b: how one might achieve it given that its power comes from a switched mode supply with just +5v, +12v & 0V!
