[gcode_macro SET_MATERIAL]
description: Dynamically adjust chamber temps, fans, and behavior based on material
# === OVERVIEW ===
# This macro sets print parameters based on the selected filament type.
# It includes logic for fan control, pressure advance tuning, and chamber temperature management.
# Each material is uniquely handled with comments, proper defaults, and warnings where applicable.
#
# === WHY USE THIS ===
# - Ensures consistent print settings per material
# - Automatically adjusts temperature and environment conditions
# - Reduces manual tuning between material changes
# - Helps enforce safety (drying warnings, chamber heat warnings, etc.)
#
# === HOW TO USE ===
# Call the macro with:
# SET_MATERIAL MATERIAL=<your_material>
#
# Example:
# SET_MATERIAL MATERIAL=ABS
#
# === SETUP REQUIREMENTS ===
# You MUST configure:
# - A chamber temperature sensor (e.g., temperature_sensor chamber_combined_mean)
# - A bed heater (e.g., heater_bed)
# - Optionally, a chamber heater (e.g., heater_generic chamber_heater)
# - A chamber circulation fan (e.g., nevermore_fan)
#
# === PARAMETERS ===
# MATERIAL: Name of the filament material preset to apply
# Supported: PLA, ABS, PETG, ASA, PC, PA, PEEK, PEK, TPU, etc.
# Extended support for exotic blends like ESD-ABS, PVDF, MetalFill, Foam PLA
#
# === NOTES ===
# - Each material includes chamber temp, fan speed, PA, and smoothing settings
# - Some materials apply Z offset compensation or recommend special nozzle/hardware
# - Certain blocks include warnings (e.g., "dry before use" or "use hardened nozzle")
# - If you do not have a chamber heater, set `ACTIVE_CHAMBER_HEATING = False`
# - You can expand this macro to include more materials as needed
# - Unknown materials fall back to a safe PLA-like default
#
# === ADVANCED ===
# This macro can be tied into slicer startup G-code or multi-material toolchanging macros.
# You can also use it in combination with filament sensors or manual menu macros.

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).

rename_existing: G106
description: Compresses fan speeds into 10–30% range if bed temp ≥ 70°C
# === OVERVIEW ===
# This macro overrides the default M106 behavior to apply a thermal-aware fan speed limiter.
# When the bed temperature is at or above 70°C, it compresses the part cooling fan speed range
# into a safer 10–30% range (i.e., 26–76 PWM) to reduce warping or delamination in high-temp materials.
#
# === WHY USE THIS ===
# - Prevents excessive part cooling when printing materials like ABS, ASA, or PC.
# - Helps maintain stable chamber temperatures and reduce thermal shock.
# - Minimizes curling or layer splitting due to sudden cooling on hot beds.
#
# === HOW TO USE ===
# Simply use M106 S<value> as usual in your G-code or slicer.
# The macro will automatically adjust the fan speed if needed based on bed temperature.
#
# === NOTES ===
# - This logic only applies when the bed temperature is 70°C or higher.
# - Below 70°C, full-range fan control is allowed.
# - You can customize the input/output compression range if needed.
# === PARAMETERS ===
# S: Standard fan speed in 0–255 (required by M106)
# Internal constants:
# min_input = 26 (10% of 255)
# max_input = 255 (100%)
# min_output = 26 (10%)
