I have been trying for many hours now to print this circular model, but have been running into inconsistent extrusion and stringing. just before printing this, I successfully printed a set of Hextraction tiles, so I'm not really sure what the issue is. I also printed this model successfully in the past with the same settings.
I am using a Sovol SV06 with stock firmware, and PLA with the hotend at 195° C.
I also did a full calibration to see if that would fix the issue, and it did not.
185C is cold for PLA. It may work for slow prints, but my personal minimum has always been around 200C and my normal print temperature is usually at 215C.
Long extrusions are probably sucking out all the heat from the nozzle and it's temporarily jamming until the filament can heat up again.
Think of the hotend as a reservoir for heat. For long extrusions, it will drain really fast. Once the hotend isn't printing for a quick second, it will fill back up really fast. At 185C, you are trying to print without a heat reservoir. I mean, it'll work, but not during intense or extended extrusions.
That was a typo, sorry, it was set at 195 C
It looks like underextrusion at speed. It might be a clog or you might want to try a higher hotend temperature. PLA can have inconsistent ideal temperatures even with the same brand due to different colors and additives between batches and 185 is on the low side.
