3pcs CR6 SE Bimetal Heatbreak Upgrade All Metal Heatbreak Titanium Alloy+Copper Bi Metal Throats for Creality CR-6 SE/Max/CR-5 PRO 3D Printer Hotend Parts

This has been the most beneficial upgrade I've made to my printer. I'm now able to print at higher Temps which is something I've struggled with in the past woth the stock equipment. If you own a snapmaker 2.0 this is a direct fit for your hot end and will allow you to print CF and nylon.

Well I really was hoping these would work, but I could not get them to work on my CR6SE. I tried them on two different hot ends and in both instances I got really horrible jams that required pulling the entire hot end apart to remove the heat break from the heater block. I ensured my Capricorn PTFE tube was cut flush and seated firmly against the heat break, but it would consistently clog upon retraction while printing as a little of the molten PLA would find a crack between the bowden tube and the heat break and jam. Putting the original heat break back in solved the problem every time I swapped it back. For some reason all three heat breaks failed to function for me, I think it might be a design issue with the cup that the bowden tube seats in. I would definitely recommend you pass on these.

2 of the 3 were bad. I was turning the heat breaks by hand, and the copper started spinning on the titanium when it bottomed out against the nozzle. I figured "oh well, I have 2 more", and the spare did the same thing. The copper can probably be marred slightly to give the titanium a tighter fit, but this is frustrating.
