# Fully dynamic Pressure Advance tuning:
# - Uses nozzle diameter from printer.cfg
# - Scales PA by nozzle and flow ratio
# - Automatically sets EXP (flow exponent) as 2x nozzle
# - Automatically sets EXP (flow exponent) as 2x nozzle diameter
# - Supports optional flow exponent factor for fine-tuning
# - Dynamically sets SMOOTH_TIME unless overridden

# SET_PA PA=0.05 FLOW=30 MAX_FLOW=70

# SET_PA PA=0.05 FLOW=25 MAX_FLOW=35 FLOW_FACTOR=1.2
# SET_PA PA=0.05 ; uses defaults with FLOW_FACTOR=1.0
