Settings to obtain a proper fillament

[mejia921]

Hi everyone! I have been trying to obtain a good filament, but so far I can only roll the PET stripe without the usual structure, so the core of the filament is empty. Once I tried to use it in the printing machine, nothing could be printed, not even the base.

I'm wondering the best temperature for the set-up and rolling speed. Any advice?

Thanks

Hi there, the core of the filament is supposed to be empty, it forms the strip into an "O" shape. You should print them at 270C and lower speed. Also reducing the tension on the extruder helps as it lowers the chance of the filament being crushed in the extruder.
