c. Moderate: Extrude filament properly and evenly. Stick to the hot bed. See picture (6-7).

In case of too high and too low, please adjust knobs under the hotbed slightly until you achieve
proper height. It may take some trial and error to achieve the best result. An example of good

Note:
1) Be sure to adjust the height at center point (position5) on the touch screen, after clicking
“OK” to save its data, you can use then knobs to adjust the hot bed at the 4 corners.
