Safety
2Safety
To safely operate the FELIXprinter, we advise that you keep the following safety recommendations in mind:
General safety
Keep children under the age of 14 out of reach of the FELIXprinter.
FELIXprinters are only suitable for professional use.
Considerations when printer is in operation.
Don’t leave the printer unattended, before making sure the first layer is printed properly
Don’t lean on the printer.
Be careful with long hair and wide clothes.
Don’t transport the printer.
Make sure all moving parts can move without any obstructions.
Don’t remove any objects from the hot plate while printing
Caution with any moving parts that move in the X, Y and Z direction. Moving parts can have a
pinching hazard.
Printer placement
Place the FELIXprinter on a stable table/desk or something with a similar height.
Place the printer on a height where children cannot reach it.
Use the FELIXprinter in a dry environment at room temperature
Electronic safety
Only use the power supplies and cables supplied by FELIXprinters.
Always turn off and unplug the printer before performing maintenance or modifications.
The power supply meets all CE mark regulations and is protected against short-circuit,
overload, over voltage and over temperature.
Ventilate
Good ventilation while printing is advised. When printing ABS, small concentrations of
styrene vapor can be released. 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, 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 10 minutes before doing maintenance or
modifications.

Printer calibration
7Printer calibration
For 3d printing, the first layer is the most important layer. It is the basis of a print job (which can take more than 70
hours in some cases). An improperly printed first layer is mostly the cause of a failed print. With the automatic
calibration features properly executed, the chance of failure will be minimized.
The calibration mechanism is dependent upon the following features on the printer.
-The probe sensor in each hot-end.
-The leveling gears underneath the bed.
So, when one of the above two systems is not working properly, the printer will not be able to calibrate.
What does the calibration do?
For the FELIX Pro 2 to properly operate the calibrations described in this chapter need to be performed.
7.1.1 Physically leveling the build plate. (automated)
To ensure the distance between the bed and the nozzles is the same over the whole build plate. This is done
automatically.
When to do this calibration?
-When changing to a new bed.
-When the first layer is not sticking to the bed
-When you see that the lines on the first layer, significantly differ in thickness from one side to the other side of
the build plate.
-After transporting the printer.
When the auto bed leveling routine is started. The following steps are performed.
1. The hot-ends heat up to 185 ˚C
2. The currently active extruder will touch the bed at 4 points.
3. The bed leveling gears turn to make the bed level. (Level in this case means that the distance between the
build plate and the hot-end is the same over the whole bed surface).
4. The probe/hot-end will touch the bed at 4 points to verify. If ok, the calibration is done, if not ok, the routine
goes back to step 2. This loop will be done max 5 times, but when the machine is in proper condition it should
take max 3 cycles.
How to do the bed leveling calibration?
Please consult the quick start manual for further instructions.
7.1.2 Z-height calibration, detecting the height difference between the two hot-ends. (automated)
The extruders must operate at the same height. Due to production tolerances and rotating mechanism of the right
extruder, this has to be calibrated. The printer will do this in an automated way.
When to do this calibration?
-After changing one of the two hot-ends or nozzles.
-When you see the first purge lines are significantly different in thickness.
The extruder height calibration routine performs the following:

Printer calibration
1. The hot-ends heat up to 185 ˚C.
2. The printer homes all axes.
3. The Extruder moves to a certain position and probes both extruders a couple of times.
How to do the z-height calibration?
Please consult the quick start manual for further instructions.
7.1.3 XY- calibration. Adjusting the x, y distance between two hot-ends. (assisted)
The distance between two extruders need to be calibrated properly in order for a dual head print to successfully
finish. If this is not done properly printed lines from both extruders might overlap too much and cause a printed
failure.
When to do this?
-After exchanging/servicing a hot-end
-When adjacent features printed with both extruders do no not properly aligning.
How to do the XY calibration?

Filament flow detection
8Filament flow detection
What is filament flow detection?
The FELIX Pro 2 features filament detection. This in general monitors the flow of filament to the printer. This features
can save print-jobs where there is a problem with filament transport, giving the user a chance to correct this and save
potentially hours of time and kg of filament.
The filament detects the following cases:
•If there is no filament present.
•If the filament is slipping.
•If there is a clog in the extruder.
How does filament flow detection work?
The filament detection is basically a wheel that runs along with the filament. The controller constantly compares the
amount of flow with the sent out extruder steps. If the difference is too large, an error will be displayed:
There are two stages.
Trigger 1. When flow is below the 1st threshold, the speed of the printer is lowered to 70%, to possibly correct the flow
deficiency. And will show “Filament slipping” on the display.
Trigger 2. When the filament flow is below the 2nd threshold. The printer will show the following error.
“Filament Jam. Click to reheat”.
When this error occurs the following happens.
-The extruder goes to the park position.
-The extruder heaters turn off (bed heater stays on).
-The printer waits for user interaction to continue.
See section trouble shooting for more information what could be the root cause for this issue.
Manually turn off filament flow detection
If for some reason the filament detection seems to fail, or in your situation it is not required or unwanted. You can
disable it manually via the host software controlling the printer.
You basically send some gcode commands directly to the printer in the send command text box. This is the required
command to disable the filament detection.
M602 S0 P1
Besides sending this code to the printer via the host-software, you can also put the line of code on a plain text file and
save that as *.gcode file and run this via the display unit interface.
Note: The filament detection function is restored, when you reset or restart the printer.

Maintenance
Print bed contact points
Make sure to keep the contact points on the bottom of the print bed clean. Use a detergent like alcohol and rub gently
with a paper towel or cloth. Check this regularly, especially, when you remove the bed a lot from the printer.
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.
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.

Trouble shooting
11 Trouble shooting
Z-sensor triggered, improper leveling (G32), homing and printing in the air.
The calibration features rely on a proper functioning of the z-probe build into the hot-ends.
Z-sensor triggered.
This message can show up when the printer is idle and one of the two z-sensors is active, while the nozzle tip is not
actually touching the bed.
This does not have to be an issue. It becomes an issue if at the start of the print this issue is not cleared.
It can usually be cleared by
-Heating the hot-ends (this happens at the beginning of each print.
-Pull down the extruders onto their contacts. In some occasions, when you pull out filament by hand, it could
sometimes pull the hot-end upwards and it can stay there.
-Do maintenance of the hot-ends
G32 leveling failed.
This is related to the z-sensor. It shows up , when a bed leveling routine is started and the z-sensor is either triggered
at the start of this routine, or it unexpectedly triggers during this routine.
How to fix z-sensor triggered
For further information please consult this guide in our download section.

“Click to reheat" dialogue, filament detection
If your print gets interrupted and you get the message “Click to reheat” on the display, that means the printer has
detected that the filament is not being fed trough at the expected rate.
The printer pauses the print job at hand and will wait for the user to check the issue. While it is waiting, the
temperature of the extruder is set to a low temperature for safety (it may take a long time before someone checks the
printer again).
If you click the blue button next to the display, the printer will first re-heat the extruder to the printing temperature
again. After that, it allows you to manually feed some filament to get things working again. You can feed filament by
turning the blue knob clockwise. If you click the button again, the printer will resume what it was doing.
Causes for this behaviour
Filament jam.
A jam can occur when the filament gets tangled on the spool.

User Manual
29 January 2018

FELIX Pro 2
www.FELIXprinters.com
Trouble shooting
Sometimes a bulge or kink in the filament causes a jam.
In this case, make sure the cause of the jam is removed before resuming the print job.
Printer has run out of filament.
Put a new spool of filament on the printer. Cut off the filament so that the end is flat. Feed the filament through the
dust filter and the Teflon tube. Insert the filament into the print head.
If the extruder is at its target temperature, feed through the new filament.
The printer will then push the old filament through the extruder.
When you are sure the new filament has properly entered the extruder, resume printing.
Very soft material (like Flex material).
The filament can get squeezed so much by the clamping mechanism that the detector misjudges the amount of
filament coming through.
It may help to decrease the clamping range (see “Howto adjust filament clamping range”).
A clogged hot end that is preventing the filament being fed through.
Nozzle is too close to the bed or printed object.
This can happen if the bed is not leveled right or the object is warping up.
The filament cannot flow through the nozzle properly, causing the filament feeding mechanism to slip or stagnate.
Level the bed and make sure the first layer adheres really good to the heated bed.
A clamping range that is too small. See this article.
No filament is coming out of extruder
The most common causes to get a clogged hot-end are (ordered from most common to least common):
Chosen print temperature too hot.
Try printing at the recommended temperatures for the chosen filament. For instance, printing PLA at 210 degrees
might work in some cases, but it is critical. The top part of the hot-end will become near the critical 60°C where the
filament becomes too soft, too soon and causing a clog.
Fan cap not closed.
The front fan cap should be flipped closed all the time when the extruder heaters are active. Failure to do so can
cause the cooled part of the extruder to become hot, and the filament will soften or melt too early, causing jamming.
Hot end not really clogged
Sometimes the extrusion is partly blocked because the nozzle is too close to the bed or to the printed object. Please
check if the z-homing of the printer is correct. Check if the printed object is deforming in such a way that it moves too
close to the nozzle.
Bad quality filament.
Make sure to get good quality filament. Dimensional tolerances and also bad consistency of the material itself can
cause trouble during printing.
Dust collector not applied around the filament.

Trouble shooting
Filament attracts a lot of dust, which can potentially all come into the hot-end. In some dusty environments this could
cause a clogged hot-end within a few hours.
Fragment of previously printed material still in extruder.
If you print a material with a high melting temperature and next a material with a low melting temperature, it may be
that a residue of the high melting temperature plastic causes issues inside the extruder. Try extruding some (20 cm)
PLA filament manually at high temperature (220 °C). Make sure to turn back the temperature to normal while slowly
extruding some more material to prevent it to coal inside the extruder.
Clog from the inside of the hot-end.
It could be that a big dust particle or debris buildup inside the hot-end tip causes clogging from the inside.
You could try the dip-and-pull method:
Insert PLA in the hot end. Heat the hot end to about 220°C. Try to extrude some material.Set the hot end temperature
to 80°C. Disable stepper motors (can be done via the Quick settings menu on the printer itself). Wait for the extruder
to reach the set temperature. Pull out the filament in one smooth and steady movement. Most times the clogging
material is attached to the solidified end of the filament.
If that fails, you can try hand-drilling the nozzle opening with a drill that matches your nozzle diameter. The best is to
do this when the extruder is warm, but be careful! We sell some small diameter drills in our web shop.
Hot-end parts are not fixed together properly.
This could cause buildup of filament in some internal cavities/edges.
Heater decoupled / DEF / DEC message on screen
This error presents itself when a part of the heater circuit is not working.
It can generally be caused by one of the following things:
Bad electrical connection with the hot end cartridge.
The white big connector of the hot end should be plugged all the way onto the printed circuit board on the print head.
If you get the error, please try to pull off the connector sideways and then plug it back on firmly.
Please note: the connector also can be plugged on back to front. This does not damage anything, but it will not work
either.
Turn off and on the printer to reset it after the hot end has been reconnected.
The heater cartridge/thermistor (= temperature sensor) is not mounted right
A bad thermal contact between components and aluminum body can cause the printer to detect that the temperature
is rising too slow to be credible.
Solution: tighten set screws that fix the heater cartridge and/or the thermistor.
Be a bit careful with the thermistor set screw, overtightening it may damage the thermistor.
The heater cartridge is broken.
The printer detects that the temperature does not rise when the heater is activated.
Solution: replace the thermistor/heater set.
The thermistor is broken.
