Hello!
I have an arduino Mega 2560, I would like to know the correct pin to control the servo. I am already able to control my machine´s stepper motors for X and Y axis but not my servo. I changed the CPU map to #define CPU_MAP_ATMEGA2560 in the config.h file and connected my steppers to pins 25,26,30 and 31, and the steppers worked fine, then, I tried to connect my servo to all the PWM pins in my Arduno but it doen't work. I will apreciate any help, Thank you!

Hello !

I connected my servo to digital pin 7 and it worked for a while but after that it did not respond to M03 Sxxx. I did check my servo to see if it burnt out but nope it didnt.

I have a problem. I don´t get any respond from the serial monitor.
I have the following equipment:

  • Arduino Mega 2560 R3
  • CNC Shield with 2x A4988 Stepper Motor Driver
    May I need to change the config.h file?
