RE: Nextruder with every hardended nozzle

That is what the V6 adapter is for

RE: Nextruder with every hardended nozzle

Thanks but it does not say anything. V6 can be E3D or Slice Engineering but if you use hardend nozzle you have different thermal expansion between vanadium for example and the brass from the Nextruder. This is the reason why I am asking ...

RE:

I'm using five adapters + five brozzl 0.6mm hardened steel nozzles without any problems with my XL. It is important to heat up to 280°c and keep this temp for some minutes, and then tighten the nozzle with the proper torque, in my case 1.5NM. No leaking since I've changed them. I won't disassemble them, I leave them as they are until they worn out. (...if this ever happens)

I got some ObXidian 0.4 nozzles last week, I have also bought the available hotend parts, so I'll change the whole hotend when using a 0.4 nozzle.

Btw, I like the vanadium nozzle from slice engineering, I'm using one in my MK3s BT LGX combo.

RE: Nextruder with every hardended nozzle

My experience with tungsten carbide nozzles and the V6 adaptor has not been great. I've used them on a handful of Minis and Mk3S with Dragon hotends for years, changing nozzles very frequently, not once had an issue. But the TC with the V6 adaptor ended up with a serious filament leak, despite hot swapping and torquing at 285 like I had one on my older printers many times. I blame it on the thermal expansion difference between the adaptor/heater block and the TC nozzles. The Dragon hotends have nickel-coated copper heater blocks. 

I have since switched to Obxidian nozzles on my Mk4 and XL printers.
