Meaning of 'E'...


What is the meaning of 'E' in the G-code?

'G92 E0' is resetting the coordinate system, rirght? But what does i mean when X and Y coordinates are followed by E?

Example: G1 123.722 Y121.910 E1.07220

Is it the distance of travel?


  • E is Extruder movement. So G92 E0 sets extruder position to 0. In G1 it is the extrusion part or retraction.
