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.
