Tried the hair spray solution on the heated bed, and that gave the best start on a print ever. Here is how I got that result:

  1. The print bed is cold
  2. The glass plate was thoroughly cleaned with normal house hold window cleaner.
  3. I sprayed the glass plate with hair spray.
  4. After 10 min idle time I started to heat the bed and prepare the print in general.

However, after 2 hours of printing the filament jammed just after the hobbed bolt in the extruder gear.

  • Solution: The tention between the idler wheel and the hobbed bolt might be to high. Therefor the filemant get deformed and jammes in the tube on its way to the hot end.
