Nextruder Adaptor - PC Blend
I've recently tried using our new Prusa Core One to print some parts for our RC cars.
The problem I'm having is when the PC blend goes through the Nextruder adaptor to the nozzle, the PC blend leaks between the the two and seeps out the gaps on to the heater block. I've cleaned it off and used it again, but the problem presides.
has anyone else had a similar problem?
RE: Nextruder Adaptor - PC Blend
You have incorrectly mounted the nozzle with the Nextruder adapter. The correct procedure is as follows: Screw the adapter cold from above into the heating block until it stops and tighten it firmly. Screw the nozzle on the other side and tighten it slightly. Then heat the entire assembly to approx. 250 - 270°C and tighten the nozzle firmly while it is hot. Do not hold the assembly by the heating block but by the hexagon on the adapter. There must be a small gap between the hexagon on the nozzle and the heating block! To avoid these problems next time, I recommend using the entire nozzle for the Nextruder. You can find the right one for you on the Prusa e-shop website.

I personally am not going to touch another V6 nozzle. It's too much hassle (for me). Even after religiously following the Prusa instructions I still had a leak issue. Others have pointed out that one needs to use 280 for the E3D nozzles. Again, for me, it's just easier to use the all-in-one Nextruder nozzle assemblies. That said, if you need to use a 0.25mm nozzle, then currently V6 is the only option.

This is almost always improper installation. The common mistake is to tighten the nozzle into the heater block, the hex touching the block. The V6 assembly requires the torque be applied nozzle to heat break; this means the nozzle HEX must never touch the heater block. A gap or 1mm of threads showing minimum, 2mm optimum between the HEX and the block. Also, for a almost a decade E3D has spec'd the V6 to be hot tightened at 280 or 285C.
Not obeying these two rules (in my experience) results in leaks.
