While I'm printing I noticed filament is coming out from the bottom(not tip) of the nozzle, around the screw, about the size of two water droplet after 4 hours of printing. That didn't concern me too much, I think I just have to tighten the nozzle after the print. but I also noticed filament is also coming out above the heat block, between the heat block and the small metal plate, about the size of half water droplet on each side. Is this normal? My printer is working normally so I don't think it's caused by a blocked nozzle.
This is where the nozzle seals to the tube. If it is not snug and have a good seal it can leak in both directions.. Make sure to tighten nozzle when heated. Do NOT over tighten or you will snap the threads right off. Make sure the top two screws are tight first. Then tighten nozzle. Do all of this heated because there is ABS between tube and heater block.
