Yeah, it stinks to have to buy a new controller shortly after they announce that they are working on a better one as stated here in the looking forward section.
Not sure if you are interested in adding a rotary but if you are maybe now is the time to look into upgrading the board? Not that I know what the options are there beyond what I’ve read here on the forum. I like the setup that @AndyCXL has here and would like to do similar on my LongMill if it’s ever in my budget.
