error: #error "No E stepper plug left for Z2!

[Niptoc]

Hello,

I want to compile MKS Robin E3 V1.0 for a CR-10 with a dual Z motor with marlin 2.0.7.2 and I get an error when compiliing:

buildroot/share/PlatformIO/scripts/../../../../Marlin/src/inc/../pins/pins.h:1410:8: error: #error "No E stepper plug left for Z2!

I have set in Configuration_adv.h #define NUM_Z_STEPPER_DRIVERS 2 // (1-4) Z options change based on how many

In the pins definition I don't see PINs for Z2. ( pins_MKS_ROBIN_E3_common.h)

Hi! MKS Robin E3 have not E1 axis, you can use Z2 interface

[Niptoc]

Hi, Sorry but I'm not sure to understand. What do you mean by using Z2 interface ?

[mks-viva]

Z1 and Z2 interface

[Niptoc]

This is what I plan to use. But are the Z1 and Z2 independant (Can we use them independantly) so that I can use the implemented feature to autocalibrate the Z axis. When I check the drawing for PINs and the PIN configuration file there are no distinction for Z1 and Z2.

[mks-viva]

They are connected in parallel. Since MKS Robin E3 has only 4 axes, you cannot define independent Z2

Ok, thank you for the answer, it is clear now :)
