Single/double arrows in manual extruder feed.

In the manual control pane, the extruder section, there is a single arrow on the lower left and a double one on the right.  What is the difference?  There's only one for retraction.


  • Retraction is always fast. For extrusion until you are at the head fast extrusion e.g. for filling a bowden is possible with right arrow while left one is using slow speed. In Printer Settings you can set both speeds.
