I'm using PLA at 205ºC. I am new in Ultimaker world, I have always used Prusa and have never had any problems. I bought an Ultimaker S3 a few days ago and I still can't put the first print for the problem mentioned above.
The filament I inserted it all the way, enough filament comes out when it is time to load it.
I consider not having to disassemble the feeder as the printer is new.
And the bed is correct leveling, I have manual leveling it two times.
