Printing Prusa PETG so confused
I have PLA printing like a dream. BUT PETG argh whats the secret. I have printed Z Calibration stuff ( 202/20.0.2mm and 70/70/0.2mm) All looks great and micrometer checks out.
So my objective is to print out parts for the Pi Zero upgrade so I can use Octoprint. Its the door I am having issues with. The instructions say print it vertically with supports, with detail settings in slic3r . I obey as its supposed to be stronger ...
So printing I get this afterwards (btw I note it flexing during printing) :
Then I printed flat cause hey what have I got to loose
This is Prusa red translucent filament using Orginal Prusa PET settings. Firmware 3.3.1 and 1.4 slic3r .
I cannot het anything PETG to print clean its a nightmare. I know PETG is the holy grail but if Prusa can do it why cant we ?

Hello,
I had also big problems with this until I dialed down the flow setting about 5%. I read it is better to under extrude petg a bit since any over extrusion will build up on the nozzle and mess the print up.

when in doubt, slower and hotter (external perimeters too)
Re: Printing Prusa PETG so confused
What slicer are you using? Slic3rPE has slower settings for PETG.

Re: Printing Prusa PETG so confused
It also looks like some pics I've seen of prints with filament containing moisture.
While not as bad as some, PETG is hygroscopic--some brands more than others.
From MatterHackers:
How do we know if filament is wet and needs to be dried?
The easiest way is to extrude some filament and watch it come out of the nozzle. If you see any bubbles, hear any hissing/popping/cracking, or see steam coming off the filament, then it’s definitely wet and needs to be dried out.
What's your climate/humidity like?
I can't say fer sure that's the problem, but drying it out in an oven for a few hours might be worth a try.
That's "MISTER Old Fart" to you!
Re: Printing Prusa PETG so confused
Thats the kind of part you want to print flat to bed and not vertical.
Look what supports done to your part, a ugly mess.
Also you should have used from build plate only supports
