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.

No skew correction option for printer.cfg?
I'm following the steps here: https://docs.ratrig.com/commissioning-guides/v-core-3-1#skew-calibration (but I've also referenced https://www.klipper3d.org/Skew_Correction.html?q=)
I printed everything, measured everything, and was able to use the SET_SKEW command and save the profile. In the printer.cfg, though, there's no place to put the variable_skew_profile item from Step 3. Just putting the [skew_correction] module in down by the USER OVERRIDES seems fine, but when I try to add in the variable_skew_profile part, Klipper crashes. What am I doing wrong?
I'm now seeing the following in the SAVE_CONFIG section (which warns us not to touch):
## [skew_correction my_skew_profile]
## xy_skew = -0.004528173929946366
## xz_skew = 0.0
## yz_skew = 0.0
So, it looks like the data is there... I just don't know what to do in printer.cfg.

Pretty flat, but tilted on initial meshes (V-Core 3.1 400mm)
