How old is that spool? I use rapid PETG but I have noticed that print quality goes to shit quick when it absorbs too much moisture. Absolute garbage prints when they hit a certain point. Id crack a fresh spool to calibrate with and see if that remedies the situation.
It's somewhat old but I keep them in dry boxes with silica beads and a hygrometer. The humidity never increased past 20% I believe. Usually stays around 15%.
Have you ever dried this filament? Silica beads won’t dry out filament, they will just keep the air in the box dry. I have definitely had to dry filament from the factory, especially PETG.
It's a few months old. I have printed with it before and while it was never perfect it was never this bad. I'll have to get back to you on a temp tower. I have one around somewhere.
I suggest printing a fresh temp tower. My bet is that temperature or retraction is off (have you fiddled with retraction lately) or the filament is super wet.
Hmm, how old is the spool? Like how long has it been open?
Also, are you sure that the filament and printer are rated to the speed Orca is putting out?
