My switching power supply has maximum current output of 8A and I'm confuse if the TB6600 can handle this current.
"Some other people advices me that the driver TB6600 only take what is the needed current"
One resources said that it can only have 5A maximum current input. Heres the link
Can I confirm that this is ok to operate?
My stepper motor is:
Nema 23 Bipolar 4 leads
3A current/phase
0.9 Ohm resistance
Having "too many" amps in a power supply is a good thing. The electrical device will just take what it needs.
The important thing is to have the correct voltage on the power supply - in this case within the range acceptable to the motor driver.
A TB6600 that is rated at 3 amps will be working right at its limit with a 3 amp motor. A driver that can handle 4 or 5 amps might be a better choice.
Always make sure to set the current limit on the motor driver to protect the motor.
Thank you for the well explained answer sir Robin. I have one more question, the TB6600 has "2.8A to 2.9A" and "3.0A to 3.2A" modes so what should i choose from this configuration?

I don't know, is the short answer. If it was mine i think I would use the lower setting.
Maybe try the lower setting and monitor (brief touch with your fingers) how hot the motor gets when working and then, if you need more torque try the higher setting and monitor the temperature. Stepper motors will normally get very hot (uncomfortable to touch). If the motor seems a great deal hotter at the higher current setting you will know it is too much.

Are you going by the label on the power supply, or have you actually tested it? I ask because if it is one of the cheap Chinese power supplies from Ebay, the voltage will have a big drop at about 1/2 the current rating.

Sir Paul, thank you for the concern. The system is already running but I'm still checking the output. The power supply is from china. I also tested the output of the power supply using my digital multimeter tester and it's output is doing fine.
