Filament flow detection
8 Filament 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 2
nd
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.

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.
