Yesterday they promoted the best dev branch up to “Main” on the Fluid Dial firmware repot on Github. It’s super impressive. Details here: Fluid Dial (Fluid NC dial pendant by Bart Dring, using M5 Stack's M5 Dial) - #153 by DougJoseph
EDIT: And today, they merged the “MSG_JSON” branch into FluidNC “Main” so now the pendant’s firmware is reckoned as “released”!
