THIS DOCUMENTATION IS PRELIMINARY FOR AN UNPUBLISHED VERSION OF PRINT3R - WORK IN PROGRESS

Commands

% print3r [<options>] <command> <file1> ...

Commands:

• print
• slice
• render

Print (Convert & Slice & Print)

% print3r print cube.scad
% print3r print cube.stl
% print3r print cube.gcode

Slice (Without Printing)

% print3r --output=cube.gcode slice cube.scad
% print3r --output=cube.gcode slice cube.stl

Render (View without Printing)

% print3r --output=test.png render cube.scad
% print3r --output=test.png render cube.stl
% print3r --output=test.png render cube.gcode

Printer Profiles

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

The most common settings are:

• machine_width: build width (X) [mm]
• machine_depth: build depth (Y) [mm]
• machine_height: build height (Z) [mm]
• nozzle_diameter: diameter of nozzle [mm]
• filament_diameter: diameter of the filament/material [mm]

Filament Profiles & General Profiles

Filament profiles and other group settings are called a 'macro', or a list of settings, which reside in settings/<macro> or settings/<slicer>/<macro> and can be reference in command-line as @<macro> like

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

whereas

• @filament/prusament 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

Profiles

• 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)
• hollow: infill 0%
• thin: single wall/perimeter

Filament Profiles

Place macros for filament specifics into settings/filament/<profile>, for example.

Other Profiles

Place macros to settings/<macro> general settings and settings/<slicer>/<macro> for slicer specific settings.

Slicer Profiles

Follow slicers are supported via --slicer=<slicer>:

• slic3r: Slic3r
• slic3r-pe: Slic3r Prusa Edition
• cura-legacy: CuraEngine 15.04 with old profiles
• cura: CuraEngine 3.x or later

settings/<slicer>/base.ini contains the base settings for a particular slicer.

Gcode Console (gconsole)

== Print3r: Gcode Console (gconsole) - use CTRL-C or 'exit' or 'quit' to exit
   for valid Gcode see https://reprap.org/wiki/G-code
conf: device /dev/ttyUSB0, connected
> 

Commands

• any valid Gcode line
• in gconsole/commands reside a few gcode script which simplify handling:
  • home, homex, homey, homez, hx, hy, hz: homing all or individual axis
  • left <n>, right <n> move left or right (X-axis) relatively
  • up <n>, down <n> move up or down (Z-axis) relatively
  • forward <n>, back <n> move forward or back (Y-axis) relatively
  • x <n>, y <n>, z <n> move each axis absolutely
  • nozzle <temp> set nozzle temperature
  • bed <temp> set bed temperature
  • off turn everything off (motors, nozzle, bed)
