[Question] should I change steppers pin before compile?

[proof666]

Hi, I’m a little confused about pins settings in trigorilla_14.h and ramps.h

I see that 1.x version has configuration for z2 stepper in https://github.com/davidramiro/Marlin-Ai3M/blob/master/Marlin/pins_TRIGORILLA_14.h which corresponding for actual wirings. But in 2.x version I see that e1 has pins that actually wired to z2.

Should I change this setting before compile 2.x version?

And another question is if I want to add additional extruder, what should I change in this files? Is enough to just add e2 block with corresponding pins?

E1 and Z2 are kinda used interchangeably since that is what's marked on the Trigorilla board. By default, the second Z motor plugs into the E1 pins on the board, hence it's configured that way. No, you don't need to change anything before compiling, it's just a small naming difference.

Yes, adding E2 and enabling its use in Configuration.h and Configuration_adv.h should work.

Can you point me to place in config where second z stepper mapped to E1?

I mean, I don’t understand how this mapping work. I see E1 usage in configuration files like it is extruder and not a Z axis. Can you explain this part a little bit deeper?

So, just so I understand, you are trying to power a second extruder via the motor from the second Z-axis, right?

I want save separate configuration for both z steppers and use pins under ext1/ext2 for additional extruder.
