[Question] should I change steppers pin before compile? about marlin-ai3m-2.0.x

[davidramiro]

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?

[davidramiro]

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.
