Help on single extruder with servo with chimera

Hello..
i need some help if is possible..

I searched a lot but i don't now if is possible or search in wrong way..

I use a mks base 1.4, with a homemade printer based in a FolgerTech i3 2020.

And i want to have 1 extruder with a servo to work with a chimera and Z Dual drive because of the of dual endstop mod...

Video in this link:
dual z axis and dual z stop

If i put 2 extruder and activate Z2 in marlin appears a error that says:

Z_DUAL_STEPPER_DRIVERS requires Z2 pins (and an extra E plug)


If i use only 1 extruder :
error "TEMP_SENSOR_1 shouldn't be set with only 1 HOTEND

Is there any change of work around this?

Thanks.

Just think on what your trying to do here for a minute...

stepper drivers
1 * X
1 * Y
2 * Z
2 * E

that is 6 stepper drivers

and how many stepper drivers are on your controller?

Thats right, 5 stepper drivers

So this is never going to work. (without adding hardware)

You say you also tried with 1 extruder which gives you an error message "TEMP_SENSOR_1 shouldn't be set with only 1 HOTEND"

which explains what to do..

Find #define TEMP_SENSOR_1 in configuration.h and make sure it is set to 0, as you only have 1 hotend

The board has:
X, Y, Z, E0, E1
Try to use E1 to Z2
I now that is possible...
My problem is the hotend...
Is there any configuration that I can change to have 1 extruder but with 2 hotend?

Take a look at SWITCHING_EXTRUDER [marlinfw.org]

Is that what you have?

as 2 hotends and 1 extruder isnt very common

Yes...
I have 1 stepper for both filament and use a servo to switch between filament. But since I have a chimera... Is to see if can use the 2 nozzle with SWITCHING_EXTRUDER..
