Guys,

Not sure if this is the best place to post but I could use some quick help.

I'm converting a Harbor Freight Micromill to CNC, I've built a Dual Power Supply from a few old Computer power supplies that are outputting right around 23 volts. So I think power is good.

I'm trying to wire up a single motor to a driver board and test this through TurboCNC but can't seem to get the drive to move. I'm certain of the wiring to the motor but not about the input side.

These are the directions I received:

J2-1 = Power Ground No Connection
J2-2 = +V (+18-36 VDC) No Connection
J2-3 = B- pin 3 (Blue)
J2-4 = B+ pin 8 (Red)
J2-5 = Bcenter pins 4 & 7 (Green & Brown)
J2-6 = Acenter pins 2 & 5 (White & Yellow)
J2-7 = A- pin 1 (Orange)
J2-8 = A+ pin 6 (Black)

Pin-out and wiring info for J1

J1-1 = Logic Ground (Assuming this should be ANY ground pin from parallel port?)
J1-2 = Enable Input, Active high (How do I know which pin from the parallel port is the Enable Input?)
J1-3 = Direction Input (Assuming this is the pin number that is assigned in the TurboCNC Axis Configuration?)

J1-4 = Step, (Also assuming this is selected in Axis configuration)

How do configure the following in TurboCNC?

The drive steps the motor at the falling edge of the
pulse applied to this input. This input should be high when idle (no
step pulses), or the current reduction will not kick in and the motor
and/or drive will get hot.

Please note that the pins 2-4 of J1 are 5V TTL/CMOS compatible.
Exceeding +5V or going below Ground (potential at J1-1) WILL most
likely damage the drive!

How do I know what the pulse width should be set to?

Can any one give me a QUICK runthrough of the minimal basics to set up TurboCNC (or any trial software) to test these drives?

your help would be VERY much appreciated!
