Description

I have encountered a problem, I use the latest marlin firmware and 5160 is OK on my motherboard. The configuration is not changed, only the drive is changed to 5161, and the information displayed using M122 is normal, but when I move the XYZ axis, there is only a little movement and then it cannot move. I used M122 to see the information changed. move_before: move_before move_x_asis: move_x_axis

Research direction
Investigate the TMC5161 driver initialization and configuration in the Marlin source code. Compare with the existing TMC5160 support in Marlin/src/module/stepper/TMCStepper.cpp and Marlin/src/module/stepper/TMCStepper.h. The user reports that M122 shows normal but movement fails after a small move. Look for differences in register settings between TMC5160 and TMC5161, particularly regarding current and microstepping. Check comments in the issue for any partial solutions or workarounds.
