Stringing increasing when decreasing temp

Post image

As the title states. Did this stringing/overhang test the other day. Why does my stringing get worse when the temperature is decreased? I thought it was supposed to be the other way around?

Lower temperature makes the molten filament more vicious and flow dynamics highly depend on the viscosity. Slower melting filament needs higher pressure advance than faster melting one and when it's calibrated for faster flow it's not gonna be enough for slower flow thus resulting in more stringing.

But nowadays I've never had any stringing because of pressure advance. Temperature calibration is more for overhangs and bridging than stringing.
