Posted · Nozzle for PVA for Mark 2 upgrade

Machine: UM2, mark 2 upgrade, olsson block

I recently did the mark 2 upgrade and will use the second nozzle for dissolvable supports(PVA). I am worried that the PVA sitting in the nozzle will mess it up. Apparently, the ultimaker 3 BB core has a internal geometry allowing it to print PVA well. Is this really an issue and are there nozzles capable of printing PVA that will fit in my UM2(M6 threads, 2.85mm)?
