    Hello Everyone,

    I built my MPCNC with Arduino Mega 2560 + RAMPS 1.4 + A4988

    • Firmware : Marlin-MPCNC_Ramps_T8_16T_LCD_32step_DualEndstop
    • X Axis : Working
    • Y Axis : Working
    • Z Axis : Working
    • Hotend : Working
    • PID : Working
    • Extruder Motor : Not Working

    After i flashed clean marlin 1.1

    • Firmware : Marlin 1.1 bugfix
    • X Axis : Working
    • Y Axis : Working
    • Z Axis : Working ( but homing wrong direction )
    • Hotend : Working
    • PID : Working
    • Extruder Motor : Working

    Where changes needed?

    Dual endstop firmware uses E0 and E1 for the second X and second Y motors, so extruder will not be possible.

    If you are not using dual endstops and you want extruders to be possible, you should try MPCNC_Ramps_T8_16T_LCD_32step instead.

    Also to get steps per mm right for A4988 you will need to change Configuration.h because by default it’s configured for 32-step microstepping.

    Hello Jamie,

    Yeah it’s working now.

    #define DEFAULT_AXIS_STEPS_PER_UNIT { 83.333, 83.333, 399, 100 }

    it’s moving good and there’s no problem except vibration. I’m printing so slow speed i will share the results soon.

    Sincerely.
