Lots of us have struggled with setting up TMC2209's on a Ai3M in full uart mode. I also struggled with getting my 3Dtouch working as well.
So I am posting my complete configuration of my Ai3M which includes
Ai3M X Carriage by ML3DPrinting found herehttps://www.thingiverse.com/thing:4469339
BLtouch Instructions by Robert Phan
FYSETC TMC2209 in full uart mode configuration by Lucasz Turowski and myself
Marlin 2.0.x for Ai3M by David Ramiro found herehttps://github.com/davidramiro/Marlin-Ai3M-2.0.x
tweaked by myself for full uart and bltouch
Notes,

Stealthchop may require to be disabled on the extruder, I do have some issues with this and sometimes revert back to spreadcycle only


I set my Linear Advance to 0.4 which seems accurate for me, I do this within Cura startup script rather than hard coding into Marlin.


I have included the full Marlin version and a compiled hex that i am currently using


also included is the stl for the bltouch mount for the Ai3M V4 X Carriage that I use


I use the 3D Touch probe from herehttps://s.click.aliexpress.com/e/_d8aZVWW


I use the FYSETC TMC2209 V3 drivers from herehttps://s.click.aliexpress.com/e/_dYw4VA6

Be sure to set the BLTouch offset (M851 Z-x.xx) Using the Ai3M V4 mount I had to use -1.90 offset.
