X Axis on E0 Axis Pins?? MKS Gen_L V1.0 board

[Horsboll]

I have to throw in the towel. I'm stuck..
I've been trying for a long time now and I can't get it to work. I am in the process of converting my 6040 CO1 laser to GRBL on an MKS Gen_L v1 board and everything works except the X axis. I'm sure the X axis is damaged.
I need 3 axis, X, Y and Z and there are 5 on the board, so I think that I shold be able to change the X axis to use E0 pins? I´m using external drivers, so I just have to change "E0 STEP" to "X STEP" and "E0 DIRECTION" change to "X DIRECTION". But I simply cannot figure out how.
I'm just not good enough to code yet to figure it out.

The only change I have made is to switch to the Ramps board, I have also changed the Spindle pin to one of the servo pins with which I make PWM 5-0 volts for the laser tube

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 ..!!

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 🤣
