Moving forward with Marlin 2.0 is going great... Now. Finally discovered the magic combination that allows me full 32bit awesomeness and not using a Duet.
It was definitely an adventure trying to figure out all the goodness but after some soldering of chips and firmware fun I have full uART control of some TMC 2208 drivers.

These clone TMC 2208 drivers needed some soldering on three pads under the chip which enable uART support aka fancy chips talks to board control. Basically just like our prusa I can control microstepping and motor current via settings and not jumpers and a manual trim pot like many printer boards.

I'm using this board for my clone Prusa with BL Touch that has an extended Z axis. In the end we will have a sweet baseline for a $20 32bit board option for everyone. You can of course choose whatever chips you like. 2208 are good but the newly released 2209's are crazy good and the god-like 5160's are my next adventure.
Shout out to Keith Bennet and Chris Riley for putting up with my questions.
I'm using this same setup for the Maker Space printer so I needed the practice since I have to teach firmware building in two weeks and Marlin 2.0 has been making me struggle with almost all failure until now. Now that I have a working base firmware and have figure out the chip soldering moving forward will be much much easier.
Praise the printer demons!!! π π π
