This fundamental shape prints very quickly, serving as a crucial test for how the retraction setting is functioning. In the attached image, you can clearly see on the left side an effective retraction of 4 mm, which works well. On the right-hand side of the picture, a second example demonstrates what happens when the retraction is set to just 1.8 mm - it causes hair-like strands to appear as the printing head moves from one leaf to the other. The retraction value is a crucial measurement in millimeters that needs to be adjusted to ensure your printer successfully retracts filament before moving on to a different position. If the retraction setting is too high, air gets trapped inside the printing head and creates bubbles. Conversely, if it's set too low, hair-like strands are produced.
