Quick! Help with controller!

[tybrenis]

Hey everyone,

My friend's father built my controllers for me. I am trying to configure it to work in Mach3.

Heres the deal. I hook up the motors, and then I turn on the power supply. I can't move the motor, so it has holding torque. Also, the controller has two leads coming off of it for step I guess.

When I touch the yellow wire, it steps the motor once. Then again when I touch it next, etc. The green one doesn't do that.

Then, it has two red leads that I assume are for direction. When I switch them, the direction the motor moves in changes.

Now I need to hook it up to Mach 3 through the parallel port. How can I do this? I know how to set the motor pins etc. in the software but everything I've tried so far has failed. I need help quick if possible!

Also, when I hook up the two red leads (direction) to the parallel port, the motor loses it's holding torque.

from what I see the red and white off the top are the connections to the motor, the black and red off the bottom are the motor power, the blue from the top is also for the motor (common ground). The orange is +5 to power the logic chip and the green is dirction, the yellow is step.

Thanks!

How should I hook it up to my connector? It looks like the image I attached. The top left is just a ground, the other 6 are the cables I need to figure out. Which ones attach to the printer port? Which pins on the port?

Thanks a ton for your help, I don't know what I'd do without it.

Thanks!

on your parelel port you would connect the green and yellow to pin (your choice of output pins) and the parelel port ground connects to the blue.

I should mention that the blue splits into two wires. It has one lead off the motor but then it splits and has two leads. What should I do with those?

from what I see you will hook only 3 to the pc, the blue green and orange as I posted above. I'm not sure what motors you have so I cant comment on the connections.

Thanks a ton. I have Astrosyn Miniangle Steppers. They are 6.0v and 1.2 amps. How much torque and speed do you think I can get with them?

[Netjams]

How many wires do your motors have?

[tybrenis]

Six wires. I believe they are unipolar.

I guess I'll just attach one blue wire, then?

EDIT: By the way, the orange one is attached to the board on the bottom. It is soldered to the top and the bottom, connecting something I guess. See pics.

EDIT: I've got it working! This is a glorious day indeed!

I'm glad to hear it
