Same stepper moving but different extruder is selected?

Basic Information:

Printer Model: Neptune 4 Max
MCU / Printer board: Manta M8P V2.0 + CB1
Host / SBC: Mainsail
klippy.log:
klippy.zip (940.5 KB)

printer.cfg (7.7 KB)

I have 2 Extruder steppers: “extruder” and “extruder1”
they are wired correctly, into motor 5 and 6 output.

when i go to my dashboard and select an extruder, see image below:

it doesn’t matter what extruder i select, the same stepper moves on my printer. ( the left one, extruder(0) )

at first i had my steppers wired incorrectly: output 4 and 5. The same happened there but instead of the left one the right one always moved (extruder1).

so they are both capable of moving (but not in the way i tell them to)
both motors have a TMC2209 installed

Heating the nozzles individually does work.

Thank you, i will work on this and report back with a solution mark or extra questions

I copied and adjusted some variables in my printer.cfg, see below, and i get my second extruder moving for not even a second before klipper shuts down and gives this error:

TMC 'extruder1' reports error: DRV_STATUS: 40190060 s2vsb=1(ShortToSupply_B!) ola=1(OpenLoad_A!) cs_actual=25 stealth=1
Once the underlying issue is corrected, use the
"FIRMWARE_RESTART" command to reset the firmware, reload the
config, and restart the host software.
Printer is shutdown

klippy (3).log (1.1 MB)
printer (1).cfg (8.8 KB)

it has something to do with my tmc2209 driver because when i remove it from my printer.cfg , it also doesn’t move but it doesn’t give a shutdown error.

after a bit more research i have found the cause, there is a problem with my wiring. 1 group of my stepper does beep with the multimeter but the otherone doesnt. there is nothing wrong with my stepper itself, i beeped the stepper.
