I've configured my GTR like this and it is working great.
Changes in config.h
#define X_DRIVER_TYPE TMC2209
#define Y_DRIVER_TYPE TMC2209
#define Z_DRIVER_TYPE TMC2209
//#define X2_DRIVER_TYPE A4988
//#define Y2_DRIVER_TYPE A4988
#define Z2_DRIVER_TYPE TMC2209
//#define Z3_DRIVER_TYPE A4988
//#define Z4_DRIVER_TYPE A4988
#define E0_DRIVER_TYPE TMC2209
Changes in config_adv.h
#define NUM_Z_STEPPER_DRIVERS 2
[...]
#define Z_STEPPER_AUTO_ALIGN
Make sure to put the jumper back into the Z2 motor pins and use E1 instead.
So it should be possible to use this board for a triple-z setup ?! Just need X,Y,Z1,Z2,Z3,E first Z goes into Z1 Port , second in E0 , third in E1 and the E-Motor in E2
Yes triple-z would be possible if a single head extruder is used otherwise you would need to upgrade the GTR with the extension board M5.
Regarding the setup above: I suggest to also add a defininition for the second Z-endstop or take care which one is used.

I think you got the order wrong; Marlin first assigns extruders and then additional Z channels to the unused E channels. So in your case, you'd end up getting:
X = X
Y = Y
Z1 = Z
E = E0
Z2 = E1
Z3 = E2
Order isnt really relevant at all ... Made it with 4 Z-Axis X , Y , E , Z , Z1 , Z2 , Z3 The "doubled" Port for 2 Z Axis is now my Extruder ... just to have it clean
How did you achieve that? Did you remap the relevant pins in the pins_XXX.h
file for the board?
Either way, I was just commenting on the order in which Marlin assigns steppers to the logical En
steppers as defined in the pins_
, where extruders (however many set by EXTRUDERS
) come first and Z-steppers last. Unless there's a way to change that logic that I'm not aware of?

Yes
Has anyone use E1 as a second Z drive? if so can you help me with what you changed in Marlin to get it to work.
Thanks in Advance
