CNCRouterParts Stepper Wiring ??

[teccboxx]

I have 4 of the 380oz steppers from cncrouterparts and I am going to use the ez g540 and a cover so I am going to re-wire and I have a question.

The wire colors I have is (red, blue, yellow and green) The spec sheet that cncrouterparts has is (black, green, red, and blue)

Does anyone know what color goes to A A- B and B-

I believe the wiring is

A Green
A- Red
B Blue
B- Yellow

Can anyone confirm I have the wiring correct???

Find out which colors are the A pair and the B pair.

If you have the motors already disconnected, then finding the pairs is easy:
1. With all the wires coming out of your motor separated (isolated) spin the rotor with your fingers. Feel how much mechanical effort it takes to roll the shaft.
2. Pick any two colored wires coming out of your motor(s) and short them together.
3. Now roll the shaft of the motor again. If it got very hard to roll over, then you found either the A pair or the B pair.
4. If the motor shaft is still easy to roll over, you haven't found a pair - so pick another set of colors and try that.
5. You will eventually find two pairs of colors that are your A pair and your B pair (which make the shaft hard to turn over).
6. Compare to the color assignment in the attached drawing.

Now, for wiring. (Try one motor first before wiring up all the motors). I think the color code in the attached drawing is pretty standard.

Hope it helps.

I just took the DB9 cover off my 380 oz steppers from cnc router parts
these were ones made before he went to the newer molded plastic ends:

6=yellow
7=blue
8=red
9=green
1 to 5 =3.5 k resister
that's what i found!

on the g540 rev4
8 and 9 on the silk screening on the unit is A phase
And 6 and 7 is B phase...
