  • 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.
