    I'm looking for a command to append to the FFF profile in Simplify3D to retract the filament at the conclusion of a print. I'm getting really tired of these clogged hot ends and thought that might be a solution when I miss the fact that the print has ended and the hot end is cooling. Is there a Gcode command for this?

    Edit the ending GCode script:

    Add a G92 E0 to reset the extruder axis to zero, then a G1 E-2. So just add the following two lines to the end.gcode script:

    G92 E0
    G1 E-2

    Change the '-2' to -however_many_mm_you_want_to_retract

    Thank you, yet again, Mark, for your assistance. I do wish there were some reference I could go to or get to fill in the obviously enormous gaps in my knowledge.
