Recent addition to Klipper as a way of managing driver thermals (power dissipation) without adding resonance. Values are 0, 1, 2, 3 which correspond to: 0x0: 100V/μs 0x1: 200V/μs 0x2: 400V/μs 0x3: 800V/μs Value (2) offers the best benefit to resonance risk.
This is the printer.cfg update with the changes made to klippy\extras\tmc2240.py. These added to lines to [stepper_x] and [stepper_y] set the slew rate to 2. (400V/μs)

Recent addition to Klipper as a way of managing driver thermals (power dissipation) without adding resonance.
Values are 0, 1, 2, 3 which correspond to:
0x0: 100V/μs
0x1: 200V/μs
0x2: 400V/μs
0x3: 800V/μs
Value (2) offers the best benefit to resonance risk. This should drop the temperatures of the X and Y driver chips without additional physical cooling while not introducing any artifacting or additional resonance to printed objects.
