Hi. I bough stepper motor 0.9deg 1.65A and trying to use it with TMC2209. I even have two theses boards (v4 and v2), because I was sure first was damaged. I successfully connected everyting, using UART mode and simple joystick to move motor, and it is rotating well, but: only 6-7-8 microsteps set…

TMC2209 strangely weak motor power
