[gcode_macro SET_CHAMBER_HEAT]
description: Modular chamber heating logic with active/passive support, includes safety checks and debug output

# === OVERVIEW ===
# This macro heats the chamber to a target temperature using either:
# 1. An active heater (like a dedicated chamber heater), or
# 2. Passive heating (using the bed heater).
# It controls the bed heater, an optional chamber heater, and a circulation fan.
# It will block until the target temperature is reached.

# === SAFETY WARNINGS ===
# - Ensure your chamber temperature sensor is correctly installed and reporting.
# - Watch your printer during the first few uses of this macro.
# - Passive mode may take a long time to reach temperature.
# - Don't overheat your enclosure — check max safe temps for your printer!

# === PARAMETERS ===
# TARGET      : (required) Target chamber temperature in °C.
# SENSOR      : (optional) Temperature sensor name (default: temperature_sensor chamber_combined_mean).
# HEATER      : (optional) Chamber heater name (used only if ACTIVE=True).
# BED_HEATER  : (optional) Bed heater name (default: heater_bed).
# FAN         : (optional) Circulation fan name (default: nevermore_fan).
# ACTIVE      : (optional) If True, uses a dedicated heater; otherwise uses passive heating.

# === USAGE ===
# SET_CHAMBER_HEAT TARGET=60 ACTIVE=True HEATER="heater_generic chamber_heater"
# SET_CHAMBER_HEAT TARGET=60 ACTIVE=False

# === OVERVIEW ===
# Heats the chamber using:
# 🔥 Active: Chamber heater + bed + fan
# ❄️ Passive: Bed heater only
# ✅ Blocks until desired temperature is reached
