Why do you have the centerpulsewith and high and low limits different for the two channels?
i did change the and kept same centre pulse width and high low limit for both steppers ....this is what i am getting in receiver however i am not able to move any of the stepper
As @Railroader said screenshots are unreadable. You need to post your new code and the output.
Also I know nothing about your RC transmitter and receiver. Maybe the transmitter is not sending or the receiver not receiving.

the transmitter is sending signals and the receiver is receiving it now however the stepper motors are not rotating according to the loop conditions I tried increasing the speed and max speed also one more thing this tb6600 stepper motor driver has stepsperrevolution i.e microsteps as constant which is nowhere mentiond in the code so will that be a reason why steppers are not rotating

You changed the max speed and set speed.
yes i did change the set speed and max speed after testing it once as at that speed there was no revolution or any change in stepper
You also changed the pin numbers. It difficult for me to debug the problem if you make changes to the code I sent you, without telling me, or why you made the changes.
How do you know the receiver is sending pulses to the arduino. Did you check it with a scope?
i have given serial.print line in code so thats why when i am moving the joysticks it shows the cw and ccw moment in serialmonitor as per my joystick movement hence i am assuming that the stepper is workig ....I changed the pins for better understanding for myself during wiring (sorry for that )
Do you have the TB6600 DIP switched set to the correct positions?
This code works a little differently
Change the pin numbers according to your wiring

}sir the stepper motor is showing slight movements but the thing is the receiver is giving very light centre pulse width for both channels so what can i do to make these pulsewidths more stronger ...i hope you understanding what i m trying to say...I am trying my best to explain you this
I'm not familiar with your RC transmitter/receiver but there is usually a way to set to min and max pulsewidths for the min and max joystick travel.
Put a Serial.println for the pulseWidth to see what they are.
I tried changing the centre pulsewidth and the end limits but the problem still seems to persist .....I observed one thing that as the transmitter is giving very very light signals at slightest deviation that time the motors are trying to move according to the joystick deviation however still i am not able to get the best solution for my problem (I did try changing various values for all centre pulsewidth and high lowlimits )

Do they match what the transmitter is sending?
Is the TB6600 configured for your motors?
Did you include the print for the pulsewidth?
What is supposed to happen when Eangle and Wangle increment to greater than 45?
