hi again,
my name is Windy, im gonna ask about my stepper driver tb6600 and stepper motor nema 23.
i want to run my stepper motor high speeed with my driver. But i dont know how to connect or wiring diagram and the coding i should use.
Please help me.......................
Hi Windy, take a look at this Instructable guide.
Post links to the datasheet for the stepper motor and for the stepper driver.
What stepper motor power supply are you using (volts and amps). High step rates generally need a high voltage.

Please help me 
i use 24 VDC 5 A or supply driver motor
Now that we can see the driver you have I can't figure out what exactly you don't understand about the wiring connections. Please explain. Best thing might be to make a simple pencil drawing showing how you think the connections should be made and post a photo of the drawing. (High artistic quality is not required).
The code in the link I already gave you should be suitable for testing.
When you get that working we can consider what else may be needed.

Thank you robin you are so kind
That looks correct. You may need to experiment to find out whether ENA should be HIGH or LOW to get the motor to work.

And remember to set the driver to either 2.5A or 3.3A, since that motor is 3A. Those cheap
stepper drivers I believe use a single chip driver and will get very hot at high current, try
2.5A rather than 3.3A. A decent driver uses discrete MOSFETs and heat dissipation is not
an issue. You probably can get away with less than 5A 24V supply unless pushing the motor
hard to full speed. Stepper drivers are buck converters and push out a lot more current than
they take from the supply (certainly at low motor speeds).
thank you for your help all 
nice to meet you
