yagv - Yet Another Gcode Viewer, v0.5.8

A fast 3D Gcode Viewer for Reprap-style 3D printers, in Python and OpenGL/pyglet

Features

• Colors segments according to their type:
  • extruding (wall, infill, support if G-code comments are enabled in slicer)
  • motion of the head to the next extrusion point
  • retracting filament
  • restoring filament
• Allows displaying layers independently to examine them (scroll up & down)
• Automagically splits the Gcode into layers
• Automatic scaling to fit the window
• Zoom, panning and rotation (same mouse-button layout as OpenSCAD)
• Supported slicers:
  • Slic3r 1.2.9: works
  • PrusaSlicer 2.1.1: works
  • Cura 4.x: works
  • Mandoline 0.8.x: works
  • Slicer4RTN 0.4.x: works (non-planar slices)
• Day/Night mode (--dark)

Supported Platforms

• Ubuntu Linux 20.04 LTS [confirmed]
• Expected to work in any Linux, Windows or macOS

Installation

% python3 setup.py install
 - OR -
% sudo python3 setup.py install

Usage

% yagv [file.gcode]

% yagv --help
USAGE yagv 0.5.4: [<opts>] file.gcode
   options:
      --help               display this message
      --dark               enable dark mode
      --bed-size=<w>x<h>   set bed size (e.g. 200x240)
                     

By default, opens data/hana_swimsuit_fv_solid_v1.gcode if no file specified

Issues

• Zoom & Panning don't work well together, zoom in/out changes focus center resolved in 0.5.3
• Retract/restore detected but invisible (0-length segments).
• Some GCodes unsupported, in particular:
  • G20: Set Units to Inches
  • G2 & G3: Arcs resolved in 0.5.8

Changes

• 0.5.8: support added for G2/G3 arc extrusions as used by ArcWelder, CHANGELOG added
• 0.5.4: better parsing arguments, adding --dark mode added
• 0.5.3: better support for Cura, Slic3r, PrusaSlicer and Mandoline distincting perimeter/wall/shell, infill and support extrusion (e.g. ;TYPE:... Gcode comments); new mouse-button layout to match OpenSCAD
• 0.5.2: new color scheme (white bg, green extrusion, red active layer), display layer# with z [mm]
• 0.5.1: setup.py with proper pyglet version to match code (pre-2.0), drawing bed grid
• 0.5.0: ported to Python3, added panning, smaller font

Given --gcode-comments is enabled for Slic3r and PrusaSlicer.

Non-Planar Slices

Gcode from Slicer4RTN, conic/tilted slicer for 4- and 5-axis FDM printers
