My Steppers not moving

[xAdhamx]

I have ramps 1.4 with mega 2560 and i connect my steppers with A4988 Driver but its not working and my HC-06 not working too but my servo is working well here’s my code :

You are trying to move motors using a Ramps 1.4 board and a (your) Arduino program. Steppers work on a Ramps board but I have never tested a servo.

First I would try the grbl-l-mega firmware to be sure all is connected OK and your ramps shield, drivers, steppers, etc are OK. You need to use the RAMPS branch.

Even if the grbl-l-mega firmware is working, it is still possible that the arduino AccelStepper library is not working with the pins you selected. So the next step would be to try the AccelStepper library using one of the AccelStepper examples and AccelStepper pin configuration. If that is working, change the pin configuration to the pin selected on the ramps board (do not use the ramps shield) and see if things are working. Last would be to try the ramps shield.

Grbl-L-Mega is modified for a lathe. It could be that the modifications broke the servo code. To test a servo, It is better to use the original grbl-mega version. To get the servo running, you could follow the same procedure.

Start by connecting just 1 stepper. If that is running, add the remaining steppers one by one.

Please let me know the results,

Best regards, Huub

I checked the file cpu_map.h for the ramps configuration and the pin mapping differs from yours

  // Define step pulse output pins.
  #define STEP_BIT_0 0  // X Step - Pin A0
  #define STEP_BIT_1 6  // Y Step - Pin A6
  #define STEP_BIT_2 3  // Z Step - Pin D46
  #define STEP_PIN(i) _PIN(STEP_PORT_##i)
  // Define step direction output pins.
  #define DIRECTION_BIT_0 1 // X Dir - Pin A1
  #define DIRECTION_BIT_1 7 // Y Dir - Pin A7
  #define DIRECTION_BIT_2 1 // Z Dir - Pin D48
  // Define stepper driver enable/disable output pin.
  #define STEPPER_DISABLE_BIT_0 7 // X Enable - Pin D38
  #define STEPPER_DISABLE_BIT_1 2 // Y Enable - Pin A2
  #define STEPPER_DISABLE_BIT_2 0 // Z Enable - Pin A8

I checked my pin definition to the ramps schematic and these are OK. Here you find a complete instruction to setup ramps and connecting to bluetooth
