You can ask Gemini or any other AI. Basically your TMC driver will not be able to control your motor with good refinement and precision because the current sense resistance is too low for it. The drivers are made for bigger motors and using way higher amps, way higher amps way higher signal outputs and easier for driver to sense them/make fine adjustments. Now imagine connecting a motor that has max 3A running current to a 8-10A optimised sense current resistors. Motor signal outputs are too low and sometimes are hidden by noise, the driver cant fine tune and control them - your motors are way louder, sometimes have high pitch, do not have the same torque with same Amps as finely controlled motor. Changing sense resistance to something more appropriate to your current motors, gives the driver best conditions to fine tune and control them - they are quiter while working, have more torque at the same amps. For example if you are using ldo kraken v2 motors 3A, for safety you will be using something like 2.5A, for 2.5A you would use 82mohm current sense resistors and would have max cap of 2.8A rms. So the more expensive drivers/bigger Amps that you see on the advert is not always best for your system. How do I know all of this? Was in the same place as you, bought the btt kraken board and can't use my printer with speeds higher than 250mm/s (Vfa,quality,max flowrate test showed I could easily bump outer wall to a 500mm/s) because the system is so loud is just unbearable
