I would really appreciate it if someone could help me with this. I’m having an issue with my Sovol SV06, which is that I get a lot of stringing. I’m still fairly new to 3D printing, so I have no idea what could cause this and how I could go about fixing this. I already searched for this issue online btw but didn’t really find anything helpful.

The only change I made to this printer is that I hooked up a Raspberry Pi 4 to it and installed Klipper and Octoprint. I’m also using PrusaSlicer with the config from here.

Edit: Forgot to mention I was using PLA for this print

    I’m going to make the assumption that is PETG you are working with. I had cobwebs like that when I tried moving over from doing PLA. There were a few things I had to work out to get better prints.

    1. Slow down the print speed and work up once you get acceptable prints. Try 40 to 50mm/s to start.
    2. Increase filament retraction. Default I think is like 0.2mm, try 1.0mm instead.
    3. Increase the travel speed. I’ve used 350mm/s, which helps break strings, as someone else already suggested.
    4. Drop the extruder temperature. PETG gets more stringy as it gets hotter. Lower temp may help, and if you aren’t trying to print at warp speed, bonding should still be good. Do small test prints to see where your cutoff is. Also, if the cooling fan on that Sovol is a bit anemic then printing cooler lets each layer solidify before the next one gets added. Hopefully you get things worked out, good luck.

      Recommend all of this and

      1. Dry your filament. This should be the first thing you do, petg is one of the more moisture sensitive filaments in my experience, it’s mostly cosmetic but can cause blobbing and it loves to stick to nozzles, I recommend a sock in general to help keep the block clean, baked on petg in setscrews sucks and I’ve abandoned blocks that are bad enough. You can clean them chemically but you need some nasty stuff, don’t recommend.

      2. What’s your extrusion multiplier? Found it better to slightly underextrude petg, helps with blobbing and stringing.

      3. Petg can still string even with everything tuned, it’s “sticky” for lack of a better term, some whispy stuff can still happen, you can minimise it but acceptable should be your target, by that mean getting it to the point where yoh don’t risk print failure, small whisps can be cleaned up with some hot air.
