Robin Nano V2 - Dual Z Steps

[RafaRS46]

Hello! I have MKS Robin No V2 board and I try to conect dual Z steppers (Z and E1), To change steps for the steppers I enable distinct_E_factors but don't work.

It looks like definition of the E1 stepper does not work.

Please, Can you help me?

Thanks!

Wouldn't this be #define Z2 instead of E1 for the second stepper?

I tried it, but don't resolve my problem.

I need to select differet steps for Z driver and E1 driver. Now, the board takes steps of E0 and E1 iqual. If I change steps on E0, steps on E1 has been changed automatically. But E1 is my dual Z. The steps for Z are different than the extruder.

I don't know how to do this.

on the steps you don't need to define two Z steps only one. It will apply to both Z

Ummm if you have to totally different motor, you must define diferent steps.

Not sure why you would use two different motors on Z.. That almost like having a two start on one side and four start on the other side.. That would be asking for problems

Yes but is possible to do and work fine if the machine is fine tuned

Now, my second stepper have the same steps than de extruder E0. I can't set the number of steps of the stepper conected to E1 port of the board (the second Z) igual than the first Z.

In fact, DISTINCT_E_FACTORS is only set for the extruder, I think there is no separate distinction between double Z in marlin

[themacboy]

If you set that one I think you can use diferent steeps in each Z drive.

That is used to assign extra E drive for multiply X, Y or Z axis

[themacboy]

An alter you need to setup how to align both using g34.

That record is from other board but I the same marlin configuration in the mks board:

I chose to define Z2 pins in the pins_MKS_ROBIN_NANO_V3_common.h to specifically set Z2 up. It eliminates the compile warnings about an undefined Z2.
