Introduction
Extruder calibration is critical to quality print results. In order to complete calibration, you will be extruding a known length of filament from the extruder and measuring it as accurately as possible. Calipers make the job easy, but a ruler with mm divisions will work fine. Just note if you are using calipers, 1/10th mm is probably more than accurate for this purpose.

Remove the output bowden tube from the extruder (the one feeding the hot end). If there is filament loaded, please unload enough that you can remove the tube from the collet.

If you have no filament sticking out of the extruder, extrude a few mm until a short amount is sticking out of the collet.

Cut this clean with the collet with side cutters. I like to depress the collet with the side cutters, but whatever method you choose, ensure you measure the same way.
