CURA Pause at Height plugin for Marlin Advanced Pause

prusaprinters

Updated install procedure for Cura 5.0 and up. I got so tired of slicing and then editing GCode before printing, that I decided to dust off my very rusty Python coding skills and tackle modifying the "Pause at Height" plugin of Cura. So, without further ado, let me introduce you to, "Pause at Height (Marlin Advanced Pause)" plugin for Cura.Features:Pause at Height or LayerOnly Pause or Pause for filament change.This plugin will only work with Marlin that has been configured with "Advanced Pause", "Park Head on Pause", and "Nozzle Park Feature."Advanced Pause is located in the Configuration_adv.h of Marlin./**Advanced PauseExperimental feature for filament change support and for parking the nozzle when paused.Adds the GCode M600 for initiating filament change.If PARK_HEAD_ON_PAUSE enabled, adds the GCode M125 to pause printing and park the nozzle. Requires an LCD display.Requires NOZZLE_PARK_FEATURE.This feature is required for the default FILAMENT_RUNOUT_SCRIPT.*/ Nozzle Park Feature is located in Configuration.h/**Nozzle Park Park the nozzle at the given XYZ position on idle or G27. The "P" parameter controls the action applied to the Z axis: P0 (Default) If Z is below park Z raise the nozzle.P1 Raise the nozzle always to Z-park height.P2 Raise the nozzle by Z-park amount, limited to Z_MAX_POS.*/ This plugin makes use of the M125 and M600 GCodes. Without the above GCodes being active in the Marlin firmware this plugin will not operate.*Cura - © 2011-2019 Ultimaker BVCura is released under the terms of the LGPLv3 or higher.*How to install pluginI have installed and tested on Windows, with Cura 4.0 and above.Install procedure for version 5.0 and aboveOpen the folder %userprofile%/appdata/roaming/curaOpen the folder of the version of Cura you are running.Copy the file 'PauseAtHeightMarlin.py' to the scripts folderRestart Cura.Install procedure for versions pre 5.0 Go to the Cura folder.Windows: Located in 'Program Files\Ultimaker Cura X.X'(where X is the version number)I don't own a Mac, the following line is from the Cura install instructions for plugins.Mac: Located in the applications folder. 2. Open the folder and find the following file path: 'plugins\PostProcessingPlugin\scripts'This folder contains a few other plugins, like 'SearchAndReplace.py' and 'PauseAtHeight.py' 3. Copy the file 'PauseAtHeightMarlin.py' into the scripts folder. 4. (Re)start CuraSample Marlin Configurations ============================The following sample configurations are from my Marlin 2.0 Bugfix - Firmware for Anycubic Kossel Delta Plus.Depending on your printer, Park Point, Feed Rates, Load and Unload Lengths, Purge Length, etc. will need to be changed.If you're already running my Marlin config on your delta, then you are good-to-go with this plugin.Note: Misconfiguring these parameters can cause printer damage. Proceed with due caution.Configuration.h#define NOZZLE_PARK_FEATURE#if ENABLED(NOZZLE_PARK_FEATURE) // Specify a park position as { X, Y, Z_raise } #define NOZZLE_PARK_POINT { -90, -50, 30 } #define NOZZLE_PARK_XY_FEEDRATE 100 // (mm/s) X and Y axes feedrate (also used for delta Z axis) #define NOZZLE_PARK_Z_FEEDRATE 100 // (mm/s) Z axis feedrate (not used for delta printers) #endif Configuration_adv.h#define ADVANCED_PAUSE_FEATURE #if ENABLED(ADVANCED_PAUSE_FEATURE) #define PAUSE_PARK_RETRACT_FEEDRATE 60 // (mm/s) Initial retract feedrate. #define PAUSE_PARK_RETRACT_LENGTH 2 // (mm) Initial retract. // This short retract is done immediately, before parking the nozzle. #define FILAMENT_CHANGE_UNLOAD_FEEDRATE 40 // (mm/s) Unload filament feedrate.
