# Copyright (c) 2020 Ultimaker B.V.
# Cura is released under the terms of the LGPLv3 or higher.
# Created by Wayne Porter
# Re-write in April of 2024 by GregValiant (Greg Foresi)
# Changes:
# Added an 'Enable' setting
# Added support for multi-line insertions (comma delimited)
# Added insertions in a range of layers or a single insertion at a layer. Numbers are consistent with the Cura Preview (base1)
# Added frequency of Insertion (once only, every layer, every 2nd, 3rd, 5th, 10th, 25th, 50th, 100th)
# Added support for 'One at a Time' print sequence
# Rafts are allowed and accounted for but no insertions are made in raft layers

# August 2024 - Designed by: GregValiant (Greg Foresi). Straightened out by: Hellaholic
#
# NOTE: You may have purge lines in your startup, or you may use this script, you should not do both. The script will attempt to comment out existing StartUp purge lines.
# 'Add Purge Lines to StartUp' Allows the user to determine where the purge lines are on the build plate, or to not use purge lines if a print extends to the limits of the build surface.
# This script will attempt to recognize and comment out purge lines in the StartUp Gcode but they should be removed if using this script.
# The setting 'Purge Line Length' is only avaialble for rectangular beds because I was too lazy to calculate the 45° arcs.
# 'Move to Start' takes an orthogonal path around the periphery before moving in to the print start location. It eliminates strings across the print area.
# 'Adjust Starting E' is a correction in the E location before the skirt/brim starts. The user can make an adjustment so that the skirt / brim / raft starts where it should.
# 'Unload' adds code to the Ending Gcode that will unload the filament from the machine. The unlaod distance is broken into chunks to avoid overly long E distances.
# Added extra moves to account for Cura adding a "Travel to Prime Tower" move that can cross the middle of the build surface.
# Added ability to take 'disallowed areas' into account.

# Cura is released under the terms of the LGPLv3 or higher.
# Created by Wayne Porter
# Modified 5/15/2023 - Greg Valiant (Greg Foresi)
# Created by Wayne Porter
# Added insertion frequency
# Adjusted for use with Relative Extrusion
# Changed Retract to a boolean and when true use the regular Cura retract settings.
# Use the regular Cura settings for Travel Speed and Speed_Z instead of asking.
# Added code to check the E location to prevent retracts if the filament was already retracted.
# Added 'Pause before image' per LemanRus
