If the steppers are Sanyo 8 wire then this information should help you with identifying the connections http://www.piclist.com/techref/io/stepper/wires.htm

There are many variants of the yuk board instructions but these are probably the best http://www.savebase.com/infobase/downloads/TB6560/TB6560_4Axis_Driver.doc

Hope this helps.

Before shooting try using Sherline 1/2 Pulse mode (Config / Ports and Pins)  ;)

Possibly they will. Check the connections as mentioned earlier.

One other thing to check is the output voltage from your PC parallel port. With a multimeter check the voltage levels between any DIRECTION pin and GROUND (pins 18-25). When jogging the axis this voltage should change between approx. 0 volts and 5 volts depending on direction of jog. If it is only making 3.3 volts then this could be your problem.

Read the info on the link on how to find the proper wires for the stepper motor. Get the motor wiring correct for one motor and then use that motor to find the driver pin out for one of the axis.

One of the problems we had with a Chinese driver was with the pin out information given. Found numerous info from different sites but all was conflicting.
What a PITA to find which pin belonged to what but will give credit to the 14 year old as he followed a matirx and got all the pins figured out by trial and error.

FWIW,
RICH
