This simulator was part of JSCut discontinued CAM package which was developed since 2014 by Todd Fleming.
During 2024-09 it was isolated and modified to be useful in offline/standalone context by Tomas Mudrunka.
Similar project used to be available since 2016-05 at www.cncwebtools.com/Apps/GCode_Simulator/index.html but features were limited and the website is defunct since 2020-08.
- Load g-code from file
- Pass settings and G-Code via URL
- Support for arcs (G02, G03, XY plane only, IJ reccomended, R experimental)
- Animation
- Works offline (no webserver needed, copy at archive.org wayback machine also works)
- V-Carving
- Visualize origin point
- Show current coordinates
- Mouse wheel zooming
- Non-square viewport supported
- Shaded milling bit
- weird V-Bit behaviour when Surface Z > 0 (perhaps we should just transpose Z when parsing g-code, and fix origin crosshair...)
- 3D view translating?
- Support for mm/inch (bit settings and G21, G20)
- Support for ball nose and radiused milling bits
- Tool library and toolchanges (eg. T1 M6)
