# ChangeAtZ script - Change printing parameters at a given height # This script is the successor of the TweakAtZ plugin for legacy Cura. # It contains code from the TweakAtZ plugin V1.0-V4.x and from the ExampleScript by Jaime van Kessel, Ultimaker B.V. # It runs with the PostProcessingPlugin which is released under the terms of the AGPLv3 or higher. # This script is licensed under the Creative Commons - Attribution - Share Alike (CC BY-SA) terms #Authors of the ChangeAtZ plugin / script: # Written by Steven Morlock, smorloc@gmail.com # Modified by Ricardo Gomez, ricardoga@otulook.com, to add Bed Temperature and make it work with Cura_13.06.04+ # Modified by Stefan Heule, Dim3nsioneer@gmx.ch since V3.0 (see changelog below) # Modified by Jaime van Kessel (Ultimaker), j.vankessel@ultimaker.com to make it work for 15.10 / 2.x # Modified by Ruben Dulek (Ultimaker), r.dulek@ultimaker.com, to debug. ##history / changelog: ##V3.0.1: TweakAtZ-state default 1 (i.e. the plugin works without any TweakAtZ comment) ##V3.1: Recognizes UltiGCode and deactivates value reset, fan speed added, alternatively layer no. to tweak at, ## extruder three temperature disabled by "#Ex3" ##V3.1.1: Bugfix reset flow rate ##V3.1.2: Bugfix disable TweakAtZ on Cool Head Lift ##V3.2: Flow rate for specific extruder added (only for 2 extruders), bugfix parser, ## added speed reset at the end of the print ##V4.0: Progress bar, tweaking over multiple layers, M605&M606 implemented, reset after one layer option, ## extruder three code removed, tweaking print speed, save call of Publisher class, ## uses previous value from other plugins also on UltiGCode ##V4.0.1: Bugfix for doubled G1 commands ##V4.0.2: uses Cura progress bar instead of its own ##V4.0.3: Bugfix for cool head lift (contributed by luisonoff) ##V4.9.91: First version for Cura 15.06.x and PostProcessingPlugin ##V4.9.92: Modifications for Cura 15.10 ##V4.9.93: Minor bugfixes (input settings) / documentation ##V4.9.94: Bugfix Combobox-selection; remove logger ##V5.0: Bugfix for fall back after one layer and doubled G0 commands when using print speed tweak, Initial version for Cura 2.x ##V5.0.1: Bugfix for calling unknown property 'bedTemp' of previous settings storage and unkown variable 'speed' ##V5.1: API Changes included for use with Cura 2.2 ## Uses - ## M220 S - set speed factor override percentage ## M221 S - set flow factor override percentage ## M221 S T<0-#toolheads> - set flow factor override percentage for single extruder ## M104 S T<0-#toolheads> - set extruder to target temperature ## M140 S - set bed target temperature ## M106 S - set fan speed to target speed ## M605/606 to save and recall material settings on the UM2 from ..Script import Script #from UM.Logger
