Printing with PETG  

Re: Printing with PETG

It probably depends on the temperature in the garage. But does your printer really print at that temperature. It shouldn't.

Re: Printing with PETG

I'll post you my SUNLU PETG settings when I finish work this afternoon, But, I could not get perfect prints at 0.15 Detail settings. just Fast 0.2 settings.
I found SUNLU PETG was a little too oozy and stringy at temperatures where bridging was successful with Detail settings (0.15mm layer height).

Re: Printing with PETG

Sorry, bit busy so have only managed to get in front of the computer today.
Just copy the following into a text file and rename it to config.ini then import to slicer. This is for SUNLU PETG which I print at 230 Deg C, I fins any higher it is just too stringy and oozy.
Note:, I use modified firmware which carries out a 7x7 mesh bed leveling so in the custon G-code for printer settings there is a line G80 N7.
If this causes you an issue, just remove the N7 part. Also the head moves to just above the bed and preheats the PINDA before carrying out mesh bed levelling.
