Yet Another Gcode Viewer

This is a fast 3D Gcode Viewer for Reprap-style 3D printers, in Python and OpenGL (via pyglet)

It was written since I could not find a visualizer that fitted my needs, i.e:

• Load large files painlessly
• Let me choose the layer to display
• Color segments according to function
• Show a full 3D view for better undertanding of the code.

Designed in Ubuntu Linux; Expected to work in any Linux, Windows or OS X

Full code at https://github.com/jonathanwin/yagv and attached

Requires:

• python 2.x (2.7.3 tested)
  http://python.org/
• pyglet 1.1+ (1.1.4 tested)
  http://www.pyglet.org

Usage:

yagv [file.gcode]

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

Features:

• Colors segments according to their type:
  • extruding
  • flying the head to the next extrusion point
  • retracting filament
  • restoring filament
• Allows displaying layers independently to examine them.
• Automagically splits the gcode into layers.
• Automatic scaling to fit the window.
• Zoom and rotation (Panning planned).

Issues:

• Panning for close inspection not yet supported.
• Retract/restore detected but invisible (0-length segments).
• Designed with Slic3r output in mind, may not support other slicing programs (suggestions/patches welcome).
• Some gcodes unsupported:
  • G91: Set to Relative Positioning (used by some slicers)
  • G20: Set Units to Inches (usage unknown)
  • Arcs (G2 & G3 ?)
