alt Hacker NewsI wish I knew how to dial in PETG fully. It prints fine for me but I still get globbing and stringing so the surface finish just isn’t that amazing.

That's definitely still where I see the appeal of PLA, and once I get through the too much bulk PETG that I own I may mix up my future purchases to have more PLA where I don't need load strength and won't have issues with high temperature usage.
I am getting reasonably consistent prints but they aren't perfect.
The long version of my tips for using PETG are:
- A Bambu Lab printer doesn't hurt since it's so nicely calibrated and idiot-proof
- Clean the build plate with dish soap and dry fully. I haven't found any need for glue stick on a textured plate.
- Using a filament that has a profile available from the manufacturer for Bambu lab printers
- Printing with the filament in the dryer with the dryer running during printing
In my case PETG had issues until I realized that on my machine it needs to go slower.
I can print PLA at 100mm/s with .25mm layers...but PETG I don't go much over 65mm/s give the same line width/layer height.
Since getting things dialed in I switched to primarily printing PETG. Although, I have no issue printing PLA, PETG or ABS when needed.
