- `SET_STEPPER_ENABLE STEPPER=<config_name> ENABLE=[0|1]`: Enable or
disable only the given stepper. This is a diagnostic and debugging
tool and must be used with care. Disabling an axis motor does not
reset the homing information. Manually moving a disabled stepper may
cause the machine to operate the motor outside of safe limits. This
can lead to damage to axis components, hot ends, and print surface.
- `STEPPER_BUZZ STEPPER=<config_name>`: Move the given stepper forward - `STEPPER_BUZZ STEPPER=<config_name>`: Move the given stepper forward
