I am using Arduino Uno R3, blink file has been uploaded and also grbl file. I am using Candle Software for the controller.I am using Tb6600 driver and cnc shield for Arduino.When I open the file and run it, it runs in candle control well, but the drivers and motors do not run.There is no response and the RX andTX LED is blinking continuously.Can't understand the problem. Is there any problem in wiring please help...

Please post schematics.
Using the TB6600 no CNC is needed.
In Arduino Uno r3 blink or grbl file is uploaded or in Arduino board RX TX leb is blinking continuously. I am still using the candle software and it receiving the gcode but the motors are not running. It was working fine some time ago but now I don't know what problem has happened. Pul- or dir- =GNDpin
Again, please provide schematics.
What would the very last sentence tell? Pul, dir = GND?
Sorry but please tell me schematic means wiring diagram or something.
Yes, wiring diagram, showing pin desinatios, power supply and its basic data.
Please look at other topics and see what schematics, wiring diagram, looks like. It's not a list of wire connections.
So can you tell me which topic will be right for me?
Are you sure that you have the stepper enable on the TB6600 drivers set to the right state to enable the motors?
How do I set right state for enabling the motors.
This is what I don't understand.
I have shown my wiring in the images, can you give me the correct wiring diagram?
I have not experience with TB6600 stepper drivers, but I have seen them used and, I think, most people just leave the EN pins unconnected.
Here is how the Uno pins relate to the CNC shield pins. These are the pins (wiring) that Grbl expects.
Why are you using the shield? It is not plugged onto the Uno in the photos. It would seem that it would be less complex for you to just connect the TB6600 drivers straight to the Uno.

At the back it is showing 2 pins for X,Y,Z. Where are the pins for the 3rd driver to be connected?Where will the third driver's pin go?
I am sorry, but i do not know what you mean. What is 3rd driver? X, Y, Z are 3 drivers, do you mean a 4th driver?
Please rephrase your question.
At the back of what?
Please answer all of my questions. It is easier to help if i have information.
Why use the CNC shield?
My question is: Does changing the motor driver change the pins also?
If I use some other driver then the Arduino's pins will have to be changed too.
If you use the CNC shield you can plug in either A4988 or DRV8825 drivers in the shield.
Before using those drivers, the coil current limit must be properly set on each driver.
Processing: IMG_20231006_171622.jpg… I use these tb6600 motor drivers.
So, if I do the wiring as shown in the picture, will it work?
Your image will not show up. To post an image, just drag and drop it into a post. Please don't make me download an image, I will not do it.
What is the voltage and current capability of your motor power supply?
12 to 24v power supply and stepper motor is nema23 stepper motor 7.2kg torque and 1 amp 4.4 ohms ,maybe i'm placing the pins wrong
I also saw on YouTube that someone is using 2,3 pin and someone is using 2,5 pin.
