Filament stuck to nozzle on UM3

[cmssss 0]

Hello Ultimaker community,

I am a new Ultimaker user, and my ultimaker 3, when printing, gets all it's filament stuck to it's nozzle. This kept happening until the filament evetually cooled onto the nozzle and got stuck. My ultimaker 3 currently has same plastic stuck to it's tip that I think can only be melted off.

Thank you,

cmssss

The nozzle is probably too far from the glass. You want the plastic squished into the glass when printing that bottom layer. So just rotate the 3 leveling knobs CCW one half turn and try again.

Thanks. Do you know how I could get the dried plastic off of the nozzle?

Just heat. Heat nozzle to 100C, come back in 10 minutes. Or if there is too much then use a hair dryer or heat gun. Get a little at a time.
