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 M84 command in the Console (this should disable the stepper motors);

  • 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").

As long as you are using the printer.cfg file from the section, you shouldn't have any issues unless there was a wiring issue from factory;
