Just wondering if anyone could tell me what the G Code is for Extruder Retract. When Slic3r finishes a print it drops a thin strip of extrusion as it the head moves away from the part. I'm thinking a retract when it finishes should do the trick ??

Just reset the E axis:

G92 E0

and move it backward:

G1 E-2 F1800

(here, 2mm, at 30mm/s).
