POLISI3DUpgrade Smooth BiMetal Heatbreak All Metal Titanium Copper Thermal Barrel Tube Compatible with Original Kraken Chimera Chimera+ Cyclops Cyclops Plus Muti Color Hotend 3D Printer

Wollte die Heartbreak nochmal nachziehen als die heiß war (250°) und auf einmal konnte ich nur noch den Heatblock drehen. Also schlechte Verarbeitung

Se los coloque a una artillery genius y me a ido perfecto.Recomendado 100%

Added this to Artillery Sidewinder V2, along with an all copper heat block. So far the best benchey I have been able to print is not quite as good as with stock setup. It is crucial to lower the retraction setting from the default value of 2. I finally arrived at value of .625 using tuning tower calibration. The default value will produce extensive stringing. Hopefully the benefit will come when I move up to a larger 0.6 mm nozzle.

Since replacing the stock heatbreak on my X1 with this one, I have seen an improvement in consistency. It seems the quality has even improved. My prints are looking great and things just seem to be overall running more smoothly. So glad I bought this!

This worked for a little bit (roughly 3 small prints) but I soon ran into issues with extruder grinding the filament. I went through a lot of steps to try and resolve, but it seemed to happen with retractions.After a while the filament would get stuck in the extruder and grind a chunk out of. When I would try and pull the filament out it would be impossible. The last time I had to take my hotend apart completely and remove the heat break to get the stuck filament out. After I pulled it out I ran another piece of filament through it to see where it was hanging and could feel a lip of some sort on the bottom portion of the bi-metal break, most likely where the inner liner meets the threads on the smooth sided one for the Artillery Genius Pro.I think what was happening is it would print fine for the first few layers but as the models got more complex and needed more retractions the filament would start getting caught somehow on that lip and cool, until it was enough to stop extrusion. When I tried to do a cold pull to get rid of the clog it would come out fine, since there was no build up and the filament was still warm (even though not melted.)I am switching it back to original until I can find a better one that does not have that lip.
