HOMING_FEEDRATE {100*60, 100*60,2*60,0} (but I have also modified Z homing code in marlin_main.cpp)

DEFAULT_ACCELERATION 750
DEFAULT_RETRACT_ACCELERATION 500

DEFAULT_EJERK 10
MANUAL_FEEDRATE {100*60, 100*60, 2*60, 5*60} (in configuration_adv.h)
Except for one aspect, this has remained my baseline through dozens of prints, including around two dozen configuration controlled prints related to ripple testing. The one aspect is that with replacement of the balance of original motors with Kysans, the Z feed rates have been increased to 2.5 mm/sec in HOMING_FEEDRATE, 3 mm/sec in DEFAULT_MAX_FEEDRATE, and 2.5 mm/sec in MANUAL_FEEDRATE. I'm also operating the Z motors with 1/4 microstepping instead of the original 1/16.

Elaborating on the 100mm/sec default print speed, I typically go for a 50mm/sec perimeter speed and a 80mm/sec solid infill speed.

I continue to like these settings, especially paired with motor drive adjustments based on how the motors perform, not on a voltage setting.
