Whelp, linear advance helps but didn’t solve the issue. Settled on 0.04K for the value after tuning it 4 times. For grins, I moved over to Prusa Slic3r and put together a quick profile and… it worked really well. I have some stringing to figure out but the gap is only there for the right-most object (top in picture). Working through a retraction test now with 9 “different extruders” to see what works the best in slic3r but looks like I’ll tune this profile up and go from there.
Thanks all for the advice, will post final results if/when I have them but looks like I’ll be working on Slic3r!
