Using a pencil sharpener gets better results.
To feed filament:
1. Grab feeding device handle and lock it open
using the pivoting ring on the handle
2. Feed the filament into the hole on the lower
part of feeding device
3. Push in the filament until it stops, when it
reaches the extruder assembly
4. Release the locked feed handle
The knob above each feeding device sets the pressure on
the feeding roller: more pressure will improve traction but
will increase the chances of ruining the filament.
The pressure is set correctly when during feeding and
retraction the handle is not moving up and down
(symptom of feed roller “chewing”) the filament).
When looking at the feeders (rear printer side) the first
one is the rightmost.
When looking at the LCD panel (front printer side) the
first extruder is the one toward you.
