I calibrated mine by removing the hot end, running 150mm of filament through the extruder, marked it close to the extruder, ran it 100mm backwards, measured, ran forwards, adjusted the firmware and repeated.Quote

It's a bit of both. If you are using SF40+, E_STEPS_PER_MM needs to be set to the number of steps required to push 1mm of filament into the extruder. There are various techniques to doing this, but I prefer marking 110mm up from the extruder on the filament and running 100mm into the extruder slowly via RepSnapper. Then you can calculate how much filament actually went into the extruder and scale your E_STEPS_PER_MM value accordingly. Repeat this process a few times and you'll get an accurate value.
