This has nothing to do with the performance of stepper motors, it just optimising some values in TMC config for quieter motors that doesn't heat that much. Temp of the motors went down around 10C and I can hold them after 10h print.
Values are calculated for stock X and Y motors
Changes:
In printer.cfg locate [tmc2209 stepper_x] & [tmc2209 stepper_y] and add this code:
driver_TBL: 1
driver_TOFF: 3
driver_HSTRT: 7
driver_HEND: 5
Explanation and source:
driver_TBL : This is a configuration setting that determines the current level to be used during the active state of the stepper motor. The value 1 indicates a specific power level for the active state.
driver_TOFF : This setting specifies the duration that the motor driver will remain in a low-power standby mode before re-engaging the active current. The value 3 refers to the duration itself, often measured in microseconds.
driver_HSTRT : This is the corresponding setting for the High-State Start Time. When the driver is transitioning from standby to active, this parameter dictates the time the high-state signal should be active to prevent issues with microstepping.
driver_HEND : This parameter is also related to the transition from standby to active, controlling the High-State End Time. It defines the end of the high-state signal when the motor driver is fully active again.

PS: calicat is there just to be there. But hey, it's much better that the benchy and it's a cat! ;)
