I have an Ender 3 with a BTT E3 Mini 1.2 Board. It means that you need to take rated current of your motor and divide it by 1.414 (there's even a comment about it in Marlin's Configuration_adv.h) to get the RMS value you should set. On the extruder however I intend to replace the driver with the new TMC2209, because of its higher current and linear advance support (for some reason I couldn’t get it to work reliably on the TMC2208). Recv: 150C The current value you set for TMC driver (at least, for 2209) is an RMS (root-mean-square) value and not a max value (like on A4988 from stock board). UART connection works fine, but X and Y endstops always show as "TRIGGERED". I can't find any information in how to install the TMC2209 to Marlin/RAMPS 1.4. I also believe that marlin 2.x doesn't always respect jerk and acceleration with new s curve algorithm, theres long threads in github about missed steps.
