Splice break inside Palette

Hi. I have a P3pro and was printing ok, but when connect two filaments the splice brake inside the Palette and the print was compromised…

The filament is all brand new and I test various settings of Heat, Compress and Cool (the last one is 3-4-0) but all off they broke the splice…

I change the filament but the problem persist.

I think maybe the problem is the filament (splice) is pressed by outgoing drive spring (that is very strong) and then broke the splice.

Any help.

Answer this question I have this problem too

Is this a good question?

Hi @virmond, I would recommend adding cooling and try reducing the compression on the settings you are using here. Please test the splice using settings 2,2,2 or 2,2,3 and increase heat and cooling from there, while keeping compression around 2-3. Please also test both the ingoing and outgoing filaments to see if they’re brittle and snap easy on their own. Are they both the same brand of filament or different?

This may not be your issue, but I found that when I have splices that break somewhere in the outgoing tube (between the palette and extruder) it appears to break during heavy retractions. I guess constant retractions put an extra stress on the splice. I reduced the amount of travel in my retractions and that seems to help with the number of failures.


I also slowed the speed of the retractions too.


also remember not to adjust your splice settings on the palette itself, you have to change the splice settings in Canvas.
