We can’t help you if you choose not to supply all the information that we ask for in the issue template.

@MitchBradley sorry , I’m new on this forum.
I usually conect Stepper motors to 6X CNC Controller by @bdring using this schematics

Stepper driver 6X CNC Controller
PUL + —> STP
DIR + —> DIR
ENA + —> ENA
PUL-/DIR-/ENA- —> GND

After using WebUi it works ok

but now, I can’t get wiring properly servomotor to 6X CNC Controller, so I really hope if anyone can help me.

#3 – MitchBradley 于 2025-05-18

Connect STP to PULSE+, DIR to SIGN+. PULSE- and SIGN- to GND.

@MitchBradley
Mr could you help me, I need to setup A-axis as a Slave axis from Y-axis.

This is my configuration in YAML file

#5 – bdring 于 2025-06-10

Do you mean you want a dual motor Y axis?

#6 – GermainTejos 于 2025-06-10

yep that’s the idea,

This is my setup

#7 – bdring 于 2025-06-10

You need a motor0: and motor1: for the Y axis.

There is an example of a XYYZ config here.

https://github.com/bdring/fluidnc-config-files/blob/main/contributed/6xCNCController/6xxyyzpwm.yaml

You can use any of the motor driver outputs for any axis and motor

@bdring your advice works! thanks a lot

Now I just need to invert direction of motor, how can I get that?

Did you search the wiki for “invert”?
