Nema 34 stepper motor vibrates but does not move

General Discussion

I’m new with klipper and 3d printer field ,
i want to run stepper motor , it just vibrate but spindle does not move ,
my config setting for stepper

“step_pin:PB5
dir_pin: PA6
enable_pin: PA7
endstop_pin: ^!PA0
position_endstop: 0
position_max: 200
position_min: 0
homing_speed: 10
full_steps_per_rotation: 200
rotation_distance:40
microsteps: 16”

what should i do

You most likely have a mis-wired stepper motor.

Chances are the cable you’re using needs to have (often the middle) two wires swapped and things will be fine.

You should follow something like:

According to your attached log, Klipper never established a successful connection to your board.
Any stepper movement under this condition is highly suspicious and may point to a deeper issue.

Since you did not provide the information as request any further aid cannot be offered.

i think wrong file upload here. now upload update file.

Are the motors wired up correctly?
What stepper drivers do you use?
Are they capable to drive a Nema 34?
What printer board do you use?
What is the PSU capable to deliver?

Before you can do some meaning moves, you have to home your system first.

What printer needs a NEMA34 stepper motor?
Does it drive several Z spindles?

In most cases those motors are used for CNC machines with external drivers and bigger power supplies.
So before continue testing please answer the questions from @EddyMI3D.

i testing on large motor and motor driver DMA860H

With this setup, I cannot offer much guidance:

  • Make sure the pins are correct
  • Make sure the pins deliver what your driver is expecting, e.g. typical step-stick modules are expecting to have the enable_pin negated with !
  • Make sure that your step_pulse_duration is what the driver is expecting

Thank you , I worked on wiring again , finally motor run
