the guide doesnt show all the pins!!

im trying to add a dual Z stepper and i cant find the stepper pin so i can put it in the config, none of the stepper are labeled on the pinout please help

NVM i see them sorry

update again

nope Z-1 stepper is not listed

ok i have figured it out, no need to change config as Z and Z2 are the same

I am right behind you on this, I am trying to add my Z2, and am not finding any references that work for the Pinout. Where did you find your pinout? I know some of the pins would be identical for Z & Z2, I was planning to have independent steppers so I could program the dual Z auto-leveling feature. I am stuck. (Does not help I have never used Klipper before.)

The dual z axis for this board is NOT independent. They should have been more clear on that. You can have two stepper motors plug into those two spots but they're going to run at the same time at the same pace they are not independent. If you want dual independent Z axis you're going to have to convert your second extruder Port into a Z1 and label your 1st zport as Z0. You will have to update your printer config.

Yeah sorry I didn't post my update, the z1 and z2 ports are tied together, if you look at the board traces they are both connected so basically only 1 driver controls them all I did was bump the current up to I believe 0.80 amps and it's totally fine driving both steppers

What z motors are you using? Creality?

this is part of my config with Z1 taking place of E1

I resolved my Z & Z1 issues. What I would up doing: I used stepper_z as default, then used E1 (Not E0) to set up Stepper_z1 for the second separate z rod control. I used my pinouts for E1, and changed my printer.cfg file similar to what Tw0pay has listed above. I also setup z_tilt, as per Klipper.3D's configuration https://www.klipper3d.org/Config_Reference.html Now, my Z rods will run separately, and tune themselves level.

Just putting this here for the search engines...On Marlin for independent z-axis, change Marlin/src/pins/stm32g0/pins_BTT_MANTA_E3_EZ_V1_0.h

// Use the same Pins as Z2 (can only have one or the other configured)
// #define E1_STEP_PIN                         PB7

// There is a Z2_Motor connector on the board, but this is not for independent control
// It works the same way as the mini skr e3v3 (it just powers both motors from one driver)
