Stringing and blobbing with a 0.6 mm nozzle
I'm running the default RatRig 3.1 400mm kit, but with a Rapido 2 and a 0.6 mm nozzle (a MicroSwiss CM2 Copper Hardened Steel V6 nozzle). I'm printing good PLA (Atomic Filament) that has recently been dried. I've run all the calibrations from the setup guide. I am still getting a ton of stringing, though (see pictures).
I have PA set to 0.01, but I tried bumping it up to 0.045, with no change.
I normally print at 205 C, but I tried dropping it to 195 C, with little change.
I normally have a retraction of 2.8 mm, but bumped it up to 3.6 mm, with no change.
I normally have a retraction speed of 55 retract/35 de-retract, but I bumped them both up to 65, with no change.
My fan is usually set to 50%, but I bumped it up to 75%, with no change.
Any idea what could be going on here? Is there some other setting that I need to change? Is it the fact that the nozzle is steel-coated? I have a nickle-plated E3D copper nozzle- would that do better? I'm at wit's end.
