This can (in some cases) cause headaches, fatigue, dizziness,
confusion, drowsiness, malaise, difficulty in concentrating,
and a feeling of intoxication.
- We recommend using filament types shown on the
FELIXprinters website. Examples PLA, PETG, ABS-X,
Glassbend etc. Other types may be toxic; please follow
instructions from the filament supplier.
Caution with heater elements
- There is a potential risk of burn, as the print head can reach
temperatures of up to 275°C and the heated bed of up to
105°C.
- Don’t place objects on the heated bed, not even when the
printer is turned off.
- Always let the printer cool down for at least 5 minutes before

Shutdown button: To properly shutdown the printer. First press the shutdown button before turning the
power switch.

8 Preparation for printing
8.1 Calibration.
IMPORTANT: Only PERFORM BED LEVELING after unboxing. The printer is already fully factory calibrated.
Bed leveling: This physically tilts the bed so the distance between nozzle and bed is the same everywhere.
When to do this?:
1. After unboxing/moving printer.
2. When you see first layer printed lines are deviating from width across the print surface.
XY and Z Nozzle calibration: These calibrations align the printheads with respect to each other to get an
optimal dual head print. When to do this?
1. After exchanging a hot-end
2. When you clearly see that during dual head printing the nozzles are not aligned in x,y or height.

8.2 Load Filament
Ensure the filament is cut off in a skew manner, so the extruder can easily grip the filament.
Press the change filament button in the home menu.
1. Select the left or right extruder
2. Press insert filament. The print-heads will warm up and can take around 1 minute.
3. Now continue by pressing insert filament. While inserting the filament, help the printer by pushing it
downwards in the extruder until you feel the printer has gripped the filament.
4. Continue extruding until filament comes out of the printhead.

8.3 Clean the print surface
The first layer is the most important layer of a print. It forms the basis for the rest of the print. To ensure the
most optimal first layer adhesion do one of the following:
First remove any filament residue from the surface, with a spatula or carefully
with the tweezers.
Second use one of the two approaches to further prepare the surface:
A. Use the already applied Kapton layer on the flex plate and clean it with
detergent like methylated spirit, 100% alcohol or acetone. It must be
absolutely grease free. Grease from fingers can ruin adhesion to the bed.
B. Use an adhesive like Magigoo, Pritt Powerstick, 3DLac or similar.
Note: When using a spray adhesives ensure the flex plate is removed from the
printer. The spray can damage the linear motion components of the machine.

9 Print from USB stick
Insert the USB stick supplied with the printer and press refresh and press USB stick button
A file-list should appear. Select a *.gcode file for direct printing.
When you press the gcode file, you get two options.
1. You can save it to the library of the device or
2. Directly print it from the USB stick. The file is temporarily copied to the screen and the print will
start. You can safely remove the USB stick without disturbing the print-process.
Start the PRINTJOB supplied with the printer to ensure proper functioning
IMPORTANT NOTES/RECOMMENDATIONS
Clean/prepare the print bed before starting a print.
Never leave the printer before visually seeing that first layer is printed ok
Always use filament accessories for proper filament guiding and long lifetime of hot-end.

11 Tips and tricks
11.1 Flexible Filaments
Our 3d printers can in general handle flexible filaments well. Depending on the amount of flexibility, you
might need to take some extra precautions to print it without trouble.
This is a best practice:
Precautions.
1. Ensure you use the correct slicing profiles for flexible filaments from our supported softwares.
2. Ensure the extruders are cleared from non-flexible filaments. It is essential that the filament does not
experience any obstructions in the hot-end barrel, before reaching the hot parts of the hot-end.
Otherwise chances of buckling filament inside the extruder are very high. Obstructions can occur if
there has been printed with some hard filament before, make sure it is removed from the barrel of the
hot-end. This can be done by extruding some hard filament and then fully retract it again. Easy way is
to do it via the display unit. Then slowly extrude the filaflex into the hot-end.
3. Adjust filament clamping range. The extruder arm pushes filament onto the extruder drivewheel.
When using flexible filaments it might be that the filament is squashed too much causing a lot of
friction and eventually it buckles and clogs the extrusion.

%20Tricks/How%20To%20-%20Adjust%20filament%20clamping%20range.pdf

Loading flexible filament.
It is recommended to load filament via the interface at the printer. Goto Control => Change filament =>
Choose the correct filament and/or temperature.
1. Cut the end of the filament in a skew manner. The extruder gears might find it difficult to get grip onto
the first part of the flexible filament which is fed into the extruder.
2. Extrude filament until the first drip comes out. Then slowly extrude more piece by piece. Do not
extrude in a continuous feed at high speed as that will increase chances of buckling.
3. Optional: Lower the overall print speed. Via the display unit take the following steps after starting the
print. Press the rotary button. Then scroll down to Speed Mul. And lower it to 50%. Then by trial and
error increase the speed.

12 Maintenance
A 3D printer is a quite complex motion system and requires maintenance.
TIP: Check our YouTube channel to see instruction video’s about maintenance.
https://www.youtube.com/user/FELIXprinters
12.1 Replace a print-head
Caution: There is a potential risk of burning, as the nozzle can reach temperatures of up to 275°
For cleaning or maintenance purposes, the hot-end can be easily removed from the FELIX Pro.
Please take the following steps:
1. Check if there is still filament loaded in the hot-end. If there is no filament loaded, then go to step 4. If
yes, from the display unit or PC interface select the correct extruder and heat it up.
2. Retract the filament from the hot-end.
3. Let it cool down.
4. Turn off the printer.

1. Pull off edge connector of corresponding print head, do NOT pull the wires.
2. Open the cover in front.
3. Pull out print-head
4. Reverse the assembly of the hot-end into the extruder assembly. Do not forget to close the lid.
IMPORTANT: Ensure the hot-end wires make the bend as shown in picture above
5. Please do the following two extruder calibrations, if you wish to properly print with dual head.
- Z-height calibration
- XY calibration
TIP: Clean hot-end exterior from filament before starting a print, to prevent blobs of plastic on your printed
object.

12.2 Dust cleaners
Filament attracts a lot of dust and small particles. Make sure the filament enters the filament holder
through the dust cleaner. After a few months of printing it is recommended to replace the dust cleaners.
12.3 Motion system
The linear bearings require almost no maintenance. Recommended is that you put a little some grease on
them every 3-4 months.
The belt tension of the x and y axis can also be checked in intervals of 3 months. Check this small movie to
see how to tension the belts.

Flow detection
The flow detection system is triggered – the printer moves to its idle position waiting for user action.
The flow detection system is triggered when there is no more filament going through the extruder or when the filament is not
extruding at the expected rate. Go to www.felixprinters.com/support to learn more.
Z-sensor error
The z-sensor triggered message should appear only when the tip of the hot-end touches the print bed.
If the message is displayed continuously go to www.felixprinters.com/support to find out how to solve this issue.
Heater sensor error
Extruder: the sensor is defect or not connected properly. Please check if the connector is placed correctly and is clean on the inside.
Heated bed: The bed temperature sensor circuit is defect. That can mean the temperature sensor, or the wiring of this sensor.
Heater error
Extruder: the heater or sensor are giving improper values. Please check if the connector is placed correctly and is clean on the inside.
Heated bed: please check if the contact pins underneath the print bed are ok.
Leveling failed
The z-sensor triggered falsely during the leveling routine or measured probe values are out of their boundaries.
Go to www.felixprinters.com/support and look for the ‘z-sensor triggered’ topic.
