PETG has always been more fraught than PLA for me but as of late it just looks like a mess.
I’m just trying to do calibration at this poiny and I’m getting this mess on the pressure advance test in Orca Slicer.
I get so much stringing, boogers, and just terrible prints. It didn’t used to be this bad. Any tips?
I’m using a Snapmaker Artisan.
It’s trying to print a pentagram.
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.
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.
Have you dried your filament/ do you live in a humid climate? That would be my first guess.
What temperature is your nozzle set to?
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?
Is this a new spool or an old spool? Have you printed this blend of PETG before? What does a temperature tower look like?
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.

Petg sucks up moisture. Dry your filament.

Yeah sounds like I may have to invest in a dryer then.

Use the box & heated bed method
