OMGEXTRD F1 extruder upgrade FLSUN super racer sr installation and setup steps.

Set E-step value:365.

Note: The 2 spring screws at the bottom of the extruder should not be tightened too tightly, which will cause too much resistance to the rotation of the motor gear!

You can test the tightness by pulling it by hand.
