The Turbo has not been used so far I think and without extensive knowledge about the soft- and hardware it is hard to get going. I think we have a few Octopus’ besides the SKR Pro 1.2, but that’s about it.
So either you are willing to learn and use google quite a lot, or you just buy one of the supported boards. On my Primo I have the Jackpot and the ease of access makes it pretty great for beginners (though I like my Estlcam board on the LowRider better :P), I can recommend it without hesitation, took me 20 minutes to set up.
There have been a few Turbos. That UART config looks right to me. IIRC, there is even a Turbo configuration, but it may not be well tested.
The turbo is a good board, but I remember it being just big enough for what we needed. Specifically, I think there are only 5 endstops, so we had to do some backflips to make it work.
It can be done. You do have to understand more than if you just bought the Skr Pro v1.2 or a Jackpot board.
