subtle wavyiness surface finish

I just switched to 3.1 upgrade, extrusion less gantry, FMMM, 4028 fan. I'm getting wavy pattern which seems to be on the thin short layer time sections.

Could the 4028 be the cause during short layer time/high rpms? What should my default, bridge and max fan speeds be for printing PLA? I'm working through some resonance graphs and trying to get input shaper right https://discord.com/channels/582187371529764864/1147599753253748958

This is probably belt related, see this guide: https://ellis3dp.com/Print-Tuning-Guide/articles/troubleshooting/vfas.html
