Nextruder V6 Nozzle Adapter Failure
Just a heads up to those using the MK4 Nextruder V6 Nozzle adapter. I have had a recently purchased one come apart between the threaded heater block insert and the steel feeding tube (image below). The tube pressed out about 1/2 way through a 7 hour print. I was running on Input Shaper mode, and I guess it does not have crash detection which compounded the problem, pushing the separated heater block onto the X axis plastic/cooling fan, causing the heater block to melt into that structure.
Specifics: 0.25mm brass nozzle, PETG running at 235C. Failed after about 5 hours of printing. I can heat up the block and push the steel tube (cold) back in, which does not seem right.
