What is the point of this Gcode?

Hi,

This more than a question is a curiosity, the printer has some profiles for SuperSlicer, in the profile there is a Gcode for before the layer change:

G92 E0

This gcode resets the movement of the extruder, I think. What does this gcode provide before each layer change?

It resets the logical position of the extruder to zero - it doesn't move the extruder stepper at all.

I don't know why it would be doing that.

@peirof it’s often used when using absolute extrusion, to reset the extruder position, because the number can get so large the the extruder loses accuracy. It is recommended to use relative extrusion with RRF, so the extruder accuracy is the same all through the print.
