This could be two things, aside from what you considered. Did you increase the speed? Because if I remember correctly the SV06 has a bit of a wimpy cooling system, and as opposed to the SV07, no extra fan on the back. Another thing to consider is that sometimes you just have a filament that is stringy, did you try a different one, or so far it’s your only option?
Petg tends to string a lot more than PLA, also, drying the filament can help
I'm using PLA. How would I go about drying it?
Edit: Just saw that someone commented how to dry it by using the printer's bed.
True about PETG, but the thing about a specific filament being stringy stands: I have a green PETG that, once it gets some time in the drier, is almost perfect. And an orange one, that can sit in the drier a whole day but still string.
The config I'm using has increased speed compared to the default settings. I heard about the cooling system too, I could try lowering the speed to see if it helps and if it does, I saw online that you can swap the fan for a bigger one. Which speeds would I have to lower, exactly?
Ya lowering the speed is a good thing to try. Also, you may have a very slight clog in the nozzle which can lead to weird behavior like stringing and under extrusion
How could I check if the nozzle is clogged?
You could swap the nozzle, or do a cold pull. Honestly it would be a little challenging to explain that well over text, especially since I am not familiar with your specific printer (I've used and own a lot of them though). The best bet would be to look up on YouTube how to do a cold pull, or swap the nozzle. Some good YouTube channels are Teaching Tech, CNC Kitchen, and Made with Layers. Teaching Tech and made with layers are probably where you will find the best info for a beginner, but CNC Kitchen is 🔥
A bit hard to tell, as every printer is different, but try a small test file at let’s say 100 mm/s? I use Cura (really, really dislike the Slic3r/Prusa Slicer/Orca interface) and here it’s called “Print Speed”. Changing that will lower the others in the same way, can’t imagine it works differently in Prusa Slicer.
That speed is already faster than what my printer settings were. I have tested lower print speeds tho but it didn't make a difference.
