Tap [Tools] then [Level] on your Finder touch screen. 

Please wait while the extruder and platform finish initial movements. After that, operate according to the guide on the touch screen.

Press [OK]

Press [YES] on the screen to verify the first point. The extruder starts to move towards the first point and the plate moves up and down to verify the distance between nozzle and plate.

When it shows that the distance is too big/too small, please loosen/tighten the corresponding nut under platform (the picture on the screen will tell you which direction to turn) until hearing the loud beep and press the [Verify] button when it appears. Please follow the prompts to adjust again until you see [OK] button. Follow prompts to complete the same sequence on the second and third leveling points and then Tap [Finish] to exit.
