NCSim

NCSim is an excellent choice for those interested in 3-axis CNC simulation. As part of the Photo & Graphics category, specifically in the 3D Design subcategory, it offers robust functionality for handling 3-axis G codes. Developed by Gershon Elber, Technion, NCSim is currently available in its latest version 1.1. The program installation file, NCSim.exe, ensures a seamless setup process.

This software is designed for Windows platforms, supporting Windows XP, Vista, 7, 8, 10, and 11, making it highly versatile and accessible to a wide range of users. With open-source licensing, NCSim allows for community contributions and modifications, enhancing its feature set over time. Additionally, the program only interprets G0, G1, G2, G3 geometric motion commands, while also providing fine-tuned control over feed-rates and spindle speeds.

One notable feature is its ability to save output geometry as a polygonal mesh, which can be exported as an IRIT file, an STL file, or an IGES file. This makes it a valuable tool for those needing diverse file formats for their 3D design projects.

Given its robust capabilities and free nature, NCSim stands out as a significant asset for the CNC simulation community. Users can easily download it from various repositories or directly from the developer's page.

Pros:

• Advanced 3-axis CNC simulation capabilities.
• Supports multiple output file formats including IRIT, STL, and IGES.
• Controls feed-rates and spindle speeds effectively.
• Available free of charge under an open-source license.
• Compatible with a wide range of Windows operating systems.

Cons:

• Limited to interpreting only G0, G1, G2, G3 geometric motion commands.
• As it’s open-source, user support might be limited compared to commercial alternatives.

Overall, NCSim version 1.1 by Gershon Elber, Technion is a powerful tool for those deeply involved in 3D design and CNC simulation. Its wide array of features and accessibility make it a strong contender in the Photo & Graphics software space.
