Hello,
I use a Creality CR-10S printer.
I have a profile for petg in my version of cura. The most important setting so far for me was to lower the printing-speed to 30mm/s instead of 60mm/s, that made a huge difference.
I can see that the printer makes retractions at other positions during the printing so the retraction functionality is ok. In this case it seems like bad luck that it is travelling between two support-towers.
Thanks,
/Tomas
