[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.

[gcode_macro SET_PA]
description: Set Pressure Advance for the printer
variable_pa: 0.04

# === OVERVIEW ===
# This macro sets the Pressure Advance (PA) and smoothing values for your printer.
# Pressure Advance compensates for pressure build-up in the nozzle, improving corners and extrusion consistency.
# The smoothing value reduces sudden changes by blending movement transitions.
#
# This macro is useful when tuning PA per-material or per-print, and can be used dynamically during a print or via your slicer.
#
# === HOW TO USE ===
# Call the macro with:
#   SET_PA PA=<advance_value> [SMOOTH=<smoothing_value>]
#
# Example:
#   SET_PA PA=0.045
#   SET_PA PA=0.050 SMOOTH=0.04
#
# === PARAMETERS ===
#   PA:      The desired pressure advance value (required)
#   SMOOTH:  Optional smoothing value (default: 0.045)
#
# === NOTES ===
# - Pressure Advance tuning is material- and setup-dependent.
# - You can call this from your slicer as a custom G-code before the print starts.
# - The value is stored in a macro variable (variable_pa) so it can be referenced or reset easily.

gcode:
    {% set pa = params.PA|float %}
    {% set smooth = params.SMOOTH|default(0.045)|float %}

    # Apply Pressure Advance and smoothing time
    SET_PRESSURE_ADVANCE ADVANCE={pa} SMOOTH_TIME={smooth}

    # Store the value for reference
    SET_GCODE_VARIABLE MACRO=SET_PA VARIABLE=pa VALUE={pa}

    # Optional: echo back confirmation (uncomment if desired)
    # {% set message = "Pressure Advance set to " ~ pa|string ~ " | Smoothing: " ~ smooth|string %}

[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.

[gcode_macro M106]
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%)
