Why my nema23 motor is moving differently

My nema motor is moving counter clockwise first and then clockwise. Its backwards than on kuokuo video.

Is my wiring wrong?

Test Direction Differences

No worries — in version v1.4 of TEST_tb6600_motor.py, the test sequence runs as follows:

forward(MOTOR_SPEED, 1600)
time.sleep(1)
backward(MOTOR_SPEED, 1600)

In earlier versions, it was:

backward(MOTOR_SPEED, 1600)
time.sleep(1)
forward(MOTOR_SPEED, 1600)

I will upload a new v1.5 version to fix this inconsistency.

Wiring Observation

I also noticed something:
Your motor wiring seems to differ from the TB6600 label.

According to the motor’s label:

• A+ → Black
• A- → Green
• B+ → Red
• B- → Blue

But based on your test results, it seems the motor is moving correctly even with a different wiring setup.

what happens if you rewire it exactly according to the label?
Would the motor behave the same way, or would the direction or smoothness change?

Feel free to test and let me know your findings.

I have wire it according to the label. It run smoothly and less heat. And the problem is in my program its forwards and than backwards. In the vidoe is backwards first and than forwards. So its run perfectly fine. Thanks for your advice.

the wiring is done base on what the seller told me. because I cant read chinese. i will change the wiring and test it again. thanks.

btw what happen if we wiring it incorrectly? will it damage the motor?

No need to worry. Incorrect wiring usually won’t damage the stepper motor, but it might cause it to vibrate, stall, or not rotate properly.
