Bad Oozing on SV06 (files.catbox.moe)

The test prints in the image use the 0.2mm detail mode and 0.07mm ultradetail mode

I recently got a SV06, my first 3D printer, about a month and a half ago. About a week ago I started to find really bad oozing/ stringing on all of my prints, to the point that any functional prints are basically unusable. So far what I have tried is:

Cleaning the nozzle, inside and out, using a damp cloth and the metal needle tool that came with the printer.
Drying the filament. I had two rolls that I was using for the current print, so I used a DIY Dryer to dry both rolls, each on 70 degrees celcius for 4+ hours.

Neither of these have worked. What should I do next?

What filament and other slicer settings? Could be too hot. Could be retraction settings. Did the oozing start when you switched nozzles? If it's a cheap Amazon nozzle it might be faulty and have a different diameter than advertised. Did you follow the correct procedure with hot tightening when switching nozzles? If not, you might have got molten filament in between the nozzle and the heat break.

Here's the filament temperature range:

Print Temp: 190-220

Bed Temp: =<65

Filament settings:

Retraction settings:

I have not switched nozzles. (Am I supposed to?)

Thanks.

Ahh, I thought you meant you had a 0.2mm nozzle, but now I see you probably meant layer height.

Moisture absorbtion is rarely a problem with PLA, but hopefully dehydration won't hurt, as long as you don't accidentally overheat it and it deforms. I've left rolls of PLA out in the open for 6 months without noticing any deterioration. Both your filaments used to print fine, and then the oozing spontaneously started with both of them?

2mm retraction should be more than enough for a direct drive extruder.

In addition to the other suggestions, you might try to dry the filament longer like 8-12 hours.

Thanks, I'll try that.
