X Axis on E0 Axis Pins?? MKS Gen_L V1.0 board about grbl-mega

[Horsboll]

I have solved the problem my self
I couldn't wrap my head around how I could determine which pins it has on X step and dir and on E0 step and dir and then have them swapped around.. I succeed by finding a GRBL that is set up to 5 akas and then went through what kind of pins it calls for the E0 axis and put them into the X axis on my own cpu_map file.. and I just went out and tried it out and now run my laser in all 3 axes ..!!

#define STEP_PORT_0 F // F-->A
#define STEP_PORT_1 F
#define STEP_PORT_2 L
#define STEP_BIT_0 0 // X Step - Pin A0 - _0 0 --> _0 4 = Pin D26
#define STEP_BIT_1 6 // Y Step - Pin A6
#define STEP_BIT_2 3 // Z Step - Pin D46

Hi @Horsboll,

The pinout mapping in cpu_map.h is describe here : https://github.com/fra589/grbl-Mega-5X/wiki/Pinout-mapping-in-cpu_map.h

Thanks it would have been helpful 👍🏻
But I figured it out already by thinking for a loooong time 🤣
