Motors do no respond when sensorless homing is on - 6x TMC2209 - MKS Rumba32 #20

Hi all, I have set UART with TMC2209 for X, Y, Z, Z2, E0, E1 and sensorless homing for X and Y as per https://github.com/makerbase-mks/MKS-RUMBA32/issues/3 with minor changes to fit my printer (bed size, step / mm, etc.). I have at the same time LCD reprap full graphic 12864 and MKS TFT35 plugged in. I can move the axis and extruder using the TFT, BUUUUUUT once I try to move axis or home from the TFT, 1) nothing moves and 2) I cannot move it anymore from the LCD. I'm unsure of the TMC status 'cause I'm still struggling to install pronterface (Win 10 here).

Any clues ?

Thanks !

Solved by reducing homing feedrate from 60x60 to 30x60. Works flawlessly now (fyi stall sensitivity 200 and 70 for X and Y respectively).
