   * **Pulses per unit**. This parameter sets the number of pulses which the controller sends to the motor drivers to move by 1 unit distance (the unit depends on CNC configuration and can be either "mm" or "inch"). The full instructions on pulses per unit setup can be found on the [[mycnc:mycnc_setup_examples#how_to_set_up_axes_and_pulses_per_unit|QuickStart page here]].
   * **Max Speed** - CNC control will limit machine speed for each axis by this value. Note that the Max Speed does not count the override % value. Be careful if you use override values more than 100%
-  * **Backlash** - Backlash value in units (mm/inch) for each axis (different for each machine depending on the hardware specifications)
+  * **Backlash** - Backlash value in units (mm/inch) for each axis (different for each machine depending on the hardware specifications). Backlash is defined as the movement of the motor which may turn slightly before any actual axis movement is present (caused by gaps between parts).
   * **Axes Mapping** - Toolpath planner uses this setting for tool motion speed calculation. Possible settings are-
     * "X", "Y", "Z", "U", "V", "W" - linear axes X, Y, Z, U, V, W

     * "Spherical correction" - Settings for 3D bevel cutting head and RTCP kinematic correction.
   * **Attach to axis**. Any of 6/8 motor output can be attached to any axis. Here you can select what axis is used for every motor output.
-  * **Inversion** - Mark the checkbox if you need to change the rotation direction for any axis.
+  * **Inversion** - Mark the checkbox if you need to change the rotation direction for any axis. That way the system will invert movement in the negative direction to be registered as positive, and vice versa.
 <code>For Dual axis configuration just attach one axis simultaneously
