Unwanted filament changes

Hi,

When I print this gcode (generated with prusa slicer), it ask me 2 filaments changes during the print on my prusa mini+ (firmware : 4.4.0).

On prusa slicer, I do not ask any filament change...

Any answer why my prusa mini+ makes these filament changes ?

 

Regards

Sybaris

 

 

Best Answer by René:

From the looks of it, there is nothing wrong with this 3mf file.

Have rendered it with prusa slicer to a Gcode file.

No color changes (M600) occur in the Gcode file.

The problem is then in the filament sensor of your printer.

Here is my Gcode file.  Cache boulon - Partie 1_0.2mm_PLA_MINI_9m.zip

Print this one, and if you still have the same problem, it is most certainly the filament sensor.

To check that, you can turn off the sensor in the controller.

Then print the object again and if you have no problems with printing it is the filament sensor.

Here is what you can do about the filament sensor.

Thanks for you answer.

You are right : When I turn off my filament sensor, I do not have the problem...

Thanks a lot for your help...
