Filament sticks to nozzle Normally, I'm all fine with my printer and filament. But today I changed the filament for another brand and no matter what, it sticks to the nozzle so nothing comes to the bed and soon my nozzle is full of PLA... I use a sheet of paper for printer to level the bed at 0.1 mm. While leveling, I get the nozzle close enough to feel a bit of resistance from the paper while moving that sheet. Please help me...
I believe the problem is not so much that the filament is sticking to the nozzle; it's that the filament is not sticking to the bed.
You've confirmed that you have correct clearance for the nozzle to bed distance. The next considerations are bed temperature and nozzle temperature. New brands often require new parameters.
Consider to raise the bed temperature 5 °C. If you're not using any adhesive medium, perhaps a bit of glue stick will help to have the filament stick better/properly.
It's unlikely that the nozzle temperature is incorrect, as too low would result in a nozzle clog, while too high would &quot;drizzle out&quot; and be everywhere, but don't reject too-high entirely.
If you can get the bed adhesion correct, your nozzle should remain clear.
