Print3r: Profiles

For each printer you define a profile, which you reference with --printer=<name> when calling print3r.

There are two inclusive ways to define your printer

• slicer-independent settings (.../printer/<name>)
• slicer-specific settings for fine-tuning (.../slicer/<slicer>/<name>)

which can reside:

• /usr/local/share/print3r - your system-wide defaults
• ~/.config/print3r - your personal individual changes
• ./settings/ (current directory when calling print3r) where you can define experimental changes

The most common (slicer-independent) settings are:

• machine_name: name of machine (e.g. Prusa i3 MK3 #1)
• machine_width: build width (X) [mm]
• machine_depth: build depth (Y) [mm]
• machine_height: build height (Z) [mm]
• nozzle_diameter: diameter of nozzle [mm] (e.g. 0.4mm)
• filament_diameter: diameter of the filament/material [mm] (e.g. 1.75)
• temperature: nozzle temperature [C] (e.g. 200)
• fill_density: fill density [%] (e.g. 20)
• layer_height: layer height [mm] (e.g. 0.3mm, max. 80% of nozzle diameter)
• perimeters: amount of lines for wall [int] (e.g. 2) or
• wall_thickness: thickness of walls [mm]
• top_layers: amount of top layers [int] (e.g. 2) or
• top_thickness: top thickness [mm]
• bottom_layers: amount of bottom layers [int] (e.g. 2) or
• bottom_thickness: bottom thickness [mm]
• start_gcode: Gcode to execute at start of print (Note: slicers sometimes preheat nozzle/bed first and then execute this code)
• end_gcode: Gcode to execute at end of print
• retraction_length: general length of retraction [mm] (e.g. 2mm)
• bed_temperature: bed temperature [C] (e.g. 0 off, or 60)
• skirts: amount of skirts (e.g. 0 or 2)
• brims: amount of brims (e.g. 0 or 5)
• rafts: amount of raft layers (e.g. 0 or 1)
• support: none, bed or everywhere
• seam: aligned, random, rear, or nearest

Adding New Printer

1. cd /usr/share/print3r/printer
2. cp default.ini myprinter.ini (system-wide) or cp default.ini ~/.config/print3r/printer/myprinter.ini (only for you)
3. edit myprinter.ini: set machine width, depth and height, nozzle diameter and filament diameter at least
4. print3r --printer=myprinter print ...
5. set environment variable PRINT3R:
   • bash: export PRINT3R printer=myprinter
   • csh: setenv PRINT3R printer=myprinter
6. you may add more settings in the environment variable with ':' as separator

If you have multiple printers of the same type, but with slight different alterations (e.g. different nozzle size), then cp myprinter.ini myprinter-1.ini and cp myprinter.ini myprinter-2.ini and edit myprinter-1.ini and myprinter-2.ini.

Note: don't change /usr/share/print3r/printer/default.ini as it will be overwritten when you upgrade print3r but rather make a copy as suggested.

Fine Tuning

Although Print3r is providing a growing slicer-independent slicing settings, some may be still missing, then you can add slicer-specific settings, for example in .../slicer/cura/myprinter.ini to list CuraEngine specifics which are considered only when cura is used as slicer (--slicer=cura).

Macros aka Other Profiles

Macros or group settings are a list of slicer-independent settings, which reside in .../macro/<macro> and/or .../slicer/<slicer>/<macro> and can be reference in command-line as @<macro> like

% print3r @filament/sienoc @medium @hollow @thin print models/cube.scad

whereas

• @filament/sienoc is a macro which defines layer 0 and general print temperatures, perhaps even print speed
• @medium defines the layer height (or general "print quality")
• @hollow sets infill to 0
• @thin sets wall/perimeters to 1

Quality Macros

• coarse: rough/coarse quality (layer height = 80% nozzle diameter)
• medium: average quality (layer height = 50% nozzle diameter)
• fine: fine quality (layer height = 25% nozzle diameter)

Misc Macros

• hollow: infill 0%
• thin: single wall/perimeter
• heavy: top/bottom/wall 3 layers/3 perimeters, 30% fill density
• light: top/bottom/wall 2 layers/2 perimeters, 20% fill density
• feather: top/bottom/wall 1 layer/1 perimeter, and 0% fill density

Filament Profiles/Macros

Place your personal macros for filament specifics into ~/.config/print3r/macro/filament/<profile>, or for system-wide usage in /usr/share/print3r/macro/filament, e.g. for example sienoc.ini:

temperature=195
first_layer_temperature=210

Other Profiles

Place macros to

• .../macro/<macro> slicer-independent settings and
• .../slicer/<slicer>/<macro> for slicer-specific settings,

whereas '...' is /usr/share/print3r (system-wide) or ~/.config/print3r/ (personal).

1. Slic3r's Z seam alignment 'random' is truly random along the perimeter, whereas CuraEngine's 'random' alignment seeks a random corner if possible.

Note: CuraEngine provides many ways to define a certain setting, but it's largely inconsistent in its command-line usage; where print3r tries to provide a consistent interface while being slicer-independent with the possibility to set slicer specific settings if needed.
