Extruder extrusion test/calibration flow rate
1. Heat up both ext. sides to 220° and change the extrusion length to 300mm
and speed to100 mm/min.
2. Make sure you have filament inside extruder tubes and they both reach the
end of the nozzle
3. Measure 300mm and 400mm from the upper end of the teflon tube on top of
the extruder mark both with a pen
4. Press Extrude
5. Aer extrusion stops, measure the real length of extrusion. If the length of
extrusion diers from 300mm, you have to adapt the stepper value settings
in the config
Note
In case it is more or less than 300mm, for example 260mm:
300/260 = 1,15 --> multiply 1,15 with the present config value and and change the
value within the config + save config
Important
When you change any value in the config you have to save it!
Filament Out Sensor
1. Cut the filament above the extruder on T0 and T1
2. Print test-sample
3. Check if printer stops immediately when filament pass through feeding
wheels
4. Change filament and press resume
5. Note if extruder starts with last line printed
