# Designed in January 2023 by GregValiant (Greg Foresi)
|
||||
# My design intent was to make this as full featured and "industrial strength" as I could. People printing exotic materials on large custom printers may want to turn the fans off for certain layers, and then back on again later in the print. This script allows that.
|
||||
# Functions:
|
||||
# Remove all fan speed lines from the file (optional). This should be enabled for the first instance of the script. It is disabled by default in any following instances.
|
||||
# "By Layer" allows the user to adjust the fan speed up, or down, or off, within the print. "By Feature" allows different fan speeds for different features (;TYPE:WALL-OUTER, etc.).
|
||||
# If 'By Feature' then a Start Layer and/or an End Layer can be defined.
|
||||
# Fan speeds are scaled PWM (0 - 255) or RepRap (0.0 - 1.0) depending on {machine_scale_fan_speed_zero_to_one}.
|
||||
# A minimum fan speed of 12% is enforced. It is the slowest speed that my cooling fan will turn on so that's what I used. 'M106 S14' (as Cura might insert) was pretty useless.
|
||||
# If multiple extruders have separate fan circuits the speeds are set at tool changes and conform to the layer or feature setting. There is support for up to 4 layer cooling fan circuits.
|
||||
# My thanks to @5axes(@CUQ), @fieldOfView(@AHoeben), @Ghostkeeper, and @Torgeir. A special thanks to @RBurema for his patience in reviewing my 'non-pythonic' script.
|
||||
# 09/14/23 (GV) Added support for One-at-a-Time print sequence.
|
||||
# 12/15/23 (GV) Split off 'Single Fan By Layer', 'Multi-fan By Layer', 'Single Fan By Feature', and 'Multi-fan By Feature' from the main 'execute' script.
|
||||
# 01/05/24 (GV) Revised the regex replacements.
|
||||
# 12/11/24 (GV) Added 'off_fan_speed' for the idle nozzle layer cooling fan. It does not have to go to 0%.
|
||||
# 01/01/25 (GV) Added 'Build Volume' fan control
