Warning: When filament is still loaded into the FELIX Pro , the hot-end
cannot be removed
The first step is to take the hot-end out of the Pro. Before this is possible, the filament that is in the machine
should be removed. When the filament is removed, let the hot-end fully cool down.
Turn off the FELIX Pro
Disconnect the cable that connects the hot-end to the mainboard. Carefully pull the connector away from
the socket.

calibrated at the FELIXprinters factory - any changes in the calibration will influence the print results.

6Place the new tip
Now that the old tip is removed, place the new tip and lock it firmly into its place.
Place the new nozzle and turn it in by hand.
To prevent the nozzle from leaking it’s best to heat up the hot end with a hot airgun or a
lighter and then tighten it a little more after that, be careful you don’t burn yourself
though. If you still see some leaking you can tighten it in the machine while it’s on
temperature for the material you want to print.

7Reconnect the hot-end to its cables
Put the cables into their slots again and carefully lock them with the small screws. Check that the cable
goes to the right side away from the handle.
Do not put too much pressure on the thermistor and heater but just
enough to feel the cables are locked in their places.
8Put the hot-end back into its slot
Firmly push the hot-end into its slot. Make sure it is pushed in all the way to the back. Push till you hear a
‘click’ sound. This means the hot-end is in the correct position.
5. Pull off edge connector of corresponding print head, do NOT pull the wires, there is also a small hook on
the fan duct to which the cable is fixed take it off this hook first.
6. Open the cover in front.
7. Rotate slightly to right
