 # 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 diameter
+# - Supports optional flow exponent factor for fine-tuning
 # - Dynamically sets SMOOTH_TIME unless overridden

 #
 # Example:
-#   SET_PA PA=0.05 FLOW=30 MAX_FLOW=70
-#   SET_PA PA=0.05     ; uses defaults (FLOW=10, MAX_FLOW=15)
+#   SET_PA PA=0.05 FLOW=25 MAX_FLOW=35 FLOW_FACTOR=1.2
