Calibration
The theoretical detection length of 2.88mm is the amount of filament that will be
extruded between each pulse of the signal. This means that if no filament
movement signal is detected after 2.88mm of filament travel command, a filament
error will be triggered.
Setting the detection distance to exactly 2.88mm may likely cause false triggers
or errors. You can treat this parameter as the sensitivity of the sensor, the higher
the number, the less sensitive the sensor will be.
The detection length needs to be adjusted depending on the mounting location of
your SFS V2.0. The further away from the extruder, the higher the number will
need to be. We recommend a starting point of 3mm. If you keep getting false
triggers, increase the detection length by 1mm increments until the problem is
resolved.
