+description: Set Pressure Advance with automatic nozzle and flow-based scaling
+variable_pa: 0.04
+
+# === OVERVIEW ===
+# Dynamically adjusts Pressure Advance (PA) based on:
+# - Configured nozzle size (from printer.cfg)
+# - Actual print flow vs max flow (defaults to 10/15 mm³/s)
+#
+# === HOW TO USE ===
+# SET_PA PA=<base_value> [FLOW=<actual_mm3/s>] [MAX_FLOW=<max_mm3/s>] [SMOOTH=<smoothing>]
+#
+# Example:
+#   SET_PA PA=0.05
+#   SET_PA PA=0.05 FLOW=35 MAX_FLOW=70
+#
+# === PARAMETERS ===
+#   PA        : Base PA for 100% flow (required)
+#   FLOW      : Actual flow rate in mm³/s (default: 10)
+#   MAX_FLOW  : Max hotend flow in mm³/s (default: 15)
+#   SMOOTH    : Optional smoothing (default: 0.045)
