PRINTBUS SETTINGS RECAP

SLICER -
Travel rate: 250 mm/sec or 15,000 mm/minute
Print rate: 100 mm/sec max, perimeters and solid layers adjusted to suit
Retraction: 15 mm/sec

MARLIN -
HOMING_FEEDRATE {100*60, 100*60,2*60,0} (but I have also modified Z homing code in marlin_main.cpp)
DEFAULT_MAX_FEEDRATE {250,250,2,15}
DEFAULT_MAX_ACCELERATION {750,750,500,500}
DEFAULT_ACCELERATION 750
DEFAULT_RETRACT_ACCELERATION 500
DEFAULT_XYJERK 20
DEFAULT_ZJERK 10
DEFAULT_EJERK 10
MANUAL_FEEDRATE {100*60, 100*60, 2*60, 5*60} (in configuration_adv.h)

Print area is equipped with a print cooler capable of providing the airflow necessary to print PLA without minimum layer time restrictions on most prints.

FOLLOWUP COMMENT: It is determined later that the 5mm/sec value for E in MANUAL_FEEDRATE is about at the limit for a sustained extrusion using 1.75mm filament. For the same amount of extruded volume, 3mm filament feeds slower. 1.5 to 1.7 mm/sec would be a more appropriate value for 3mm filament.
