Stringing and Holes - HELP 🙁
Hello everyone, I've tried so many things to try to fix my printer and calibrate it, but nothing seems to work. Here are my best so far settings of the printing, and a picture of the calibration pillars I've been using. I very recently perfected the first layer calibration and clean the extruder to the nines. I use good quality PLA from filamentum. Any suggestions will be tried!
RE: Stringing and Holes - HELP 🙁
...before using a new filament for the first time, I would recommend printing a temptower with the Prusa presets. This allows you to adjust temperatures and fan settings and optimize them if necessary.

Is this a new printer?
You appear to have three issues together -
First, reset to defaults.
Next dry your filament.
Then print a first layer calibration pattern and show us the result *on the print sheet*
After that we may look at belt tensions...
Cheerio,

Hello!
Thank you for your quick responses. I dried the filament, and printed out a first layer calibration. It's printing the same pillars with defaults right now, but I thought I would update the first layer cal. now!
Thank you in advance,

And here's the re-print with system defaults (0.15 Quality preset, 20% infill) it looks like drying it did have a good effect on the holes, but still some nasty stringing and not-that smooth edges and top.
It looks like you can usefully dry the filament more.
Your first layer is on the low end of acceptable; that's ok, it'll be a little longer before you have to recalibrate for nozzle wear. Have you returned thr first layer temperature to the Filamentum default?
And your belt tension is not as bad as I feared but it would still be worth printing this:

It MUST be printed in Prusament PETG or the spring tension will be wrong.
Cheerio,

Hello again friends, I've dried my filaments and even have a filament dryer now since it realized the humidity is actually super high! I printed with the defaults again with a raised z-calibration and there was some serious improvement! But still SOME stringing. I also tested the belt and its tight. Any recommendations?
