actually im printing without VHIGHCHM and without VHIGHFS ( driver_VHIGHCHM: 0 & driver_VHIGHFS: 0 ) and with TPFD = 2 ( driver_TPFD: 2 )

best results so far in my case: regarding stepper motor noise and print surface - without VHIGHCHM and VHIGHFS set there is also no need to change the tmc5160.py to add the thigh field
With these ( fullstep aka CHM = 1 ) settings, im actually driving 15k acceleration and 800mm/s for travel moves via macro ( Custom Travel Acceleration ) - works great with 2A 0,9 stepper motors
