# Verify Stepper Motor Enable Pin

This section explains how to verify if all of the printer axes can move freely when the stepper motors are disabled.

* Go to your Anycubic Vyper 3D printer and physically check that you can move;
  * The print head (left and right);
  * The print head (up and down);
    * You don't have to move it very far you are just confirming that the motors are not engaged;
  * The print bed (front and back);
* If they do not move freely;
  * Send a <mark style="color:red;">`M84`</mark> command in the <mark style="color:red;">`Console`</mark> (this should disable the stepper motors);

![M84 Command](https://3358793419-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FEUZ4ecqSLgI2D4esAcVS%2Fuploads%2FLUpqk3NttwHSCe3net6y%2Fstepper1.png?alt=media\&token=d5e7fd2e-947c-4bd8-9d63-0bcad6d626c8)

* As long as you are using the <mark style="color:red;">`printer.cfg`</mark> file from the [Anycubic Vyper Klipper Config File](/klipper-installation-for-anycubic-vyper/printer-configuration-file.md) section, you shouldn't have any issues unless there was a wiring issue from factory;
* If any of the axes still cannot move freely, then verify the stepper 'enable\_pin' configuration for the given axis. On most commodity stepper motor drivers, the motor enable pin is 'active low' and therefore the enable pin should have a "!" before the pin (for example, "enable\_pin: !ar38").
