Previewing G-Code

From ShapeOko
Jump to: navigation, search

Note that some Communication / Control programs have previewing functionality built in.

Of especial note is https://github.com/grbl/grbl-sim which allows one to validate that Grbl will run a given G-code file.

In a class by itself is Forum user GrblGru's full 3 dimensional virtual machine simulation in software:

GrblGru = Free 3D-Simulation for ShapeOko2

which provides a way to visually simulate a workflow from end-to-end w/o the need to have a physical machine. Please note that that link takes one to the first page of the discussion. There is additional information (and newer versions) in later posts. This has since expanded to include CAM functionality.[1]

Type Name/Link Description
Verify (opensource) CAMotics (previously named OpenSCAM) CAMotics is an Open-Source software which can simulate 3-axis NC machining. It is a fast, flexible and user friendly simulation software for the DIY and Open-Source community. Works on Linux, Mac OS X and Windows
Optimize (opensource) gcodemillopt gcodemillopt is Open-Source software which will optimizer gcode produced by software like MakerCAM. It does this by arranging gcode so that cutting operations are ordered to minimize the distance between cuts. When used with the -laser option it will convert G1 Z and G0 Z codes to M3 and M5 codes to turn on and off a laser instead of moving the Z axis. Written in open source C++ it should compile on most platforms. A 32-bit Windows binary is available in github along with the source code. If renamed to gcodelaseropt the -laser flag is enabled automatically.
Preview (opensource) pygcodeviewer Python based simple G code viewer.
Preview (opensource) yagv Yet Another Gcode Viewer

Fast 3D Gcode Viewer for Reprap-style 3D printers, in Python and OpenGL (via pyglet).

Verify (opensource) Pleasant3D Mac OS X 10.6 or later previewer for STL and G-Code files.
Verify (opensource) Repetier-Host Intended for 3D printers, some users have found it useful as a previewer.
Verify CNC Simulator Windows program to simulate and test G-code before sending to the machine. Requires fairly recent version of dot.net.
Verify (opensource) CNC Simulator (Sourceforge) CNC lathe machine simulator. Simulates the path the tool of a CNC lathe takes for a given program. The simulation is two-dimensional, with provision for final view in 3D using OpenGL.
Verify CNC Viewer Fast gcode parsing using Regular Expressions, Multiple viewports, Dynamic View manipulation, Selection, Tool number filter, Printing.
Verify / Edit (Free) NC Corrector Verify tool path and view and edit G-code. A bit sluggish on older machines.
