Greetings everyone!
I need some help please, I am trying to print with PETG filament and I cant make it!
The printer is new, I am noob, I tried to find info on the net, found some profiles for cura,
tried them but with no luck!
The first attempt was by far very bad! I managed to get something better in the process but not the
quality I want! The printing is very very bad and the model to be printed has many open spaces
between the layers and it is not solid.
I can print only if I use raft beneath the model, if i print the model directly all I get is strings!
The bed is the one that comes with the printer and the filament is from Spectrum (polish brand).
The software i have is cura 4.8.
The last parameters that worked well but not excellent is:

Extruder Temp 255C
Bed Temp 110C

The rest of the parameters are what the profile has from the youtuber Technivorous.
Any advice would be appreciated!
Thank you.
