Using 'Triffid Hunter's Calibration guide -
After a pronterface manual extrude of 100mm, I get 16mm through the extruder.
How do you know that only 16mm is extruded when you try to extrude 100mm if you don't extrude at any speed?
To extrude 100mm you had a speed set for the extrusion, if this speed is too high you could be losing steps meaning the the filament will be moved less than 100mm. The speed is set in pronterface. Use a maximum of 5mm/s as the extrude speed when calibrating.
