Why G-Code Deserves More Attention

Make America Not Use Slow G-Code

(And why this matters far beyond borders)

For decades, inefficient G-code has quietly shaped CNC manufacturing in ways many shops have simply learned to accept. Slow feedrates. Unnecessary home returns. Post processors that can’t be edited or trusted. Problems that cost time, money, and confidence—without always being obvious.

It’s time to stop treating these issues as “just part of the job.”

🛑 No more slow G-codes 🛑 No more illegal or unnecessary home returns (G28) 🛑 No more read-only CNC post processors

At MANUS Software, we believe inefficient machining isn’t a limitation of CNC technology—it’s a limitation of the tools and workflows we’ve been using. And changing that requires more than small tweaks. It requires a shift in how G-code is created, verified, and improved.

Rethinking the role of G-code

G-code is the final authority on the shop floor. No matter how advanced a CAM system is, what truly matters is what the machine actually executes. That’s why optimizing toolpaths alone is not enough—and why post-processing, simulation, and optimization must work together as a single system.

This is the foundation of how we’re reshaping CNC workflows.

Building blocks of a new G-code workflow

🔧 MANUSpost Developer Post processors should be understandable, editable, and reusable. MANUSpost Developer enables users to design, modify, and deploy CNC post processors without writing code—independent of CAM software and free from black-box logic. It puts control back where it belongs: with the people who use the machines.

🎯 MANUSsim Simulation should reflect reality. MANUSsim performs true G-code–driven CNC simulation—not CAM toolpath previews. What runs on the machine is exactly what you see in simulation, including feedrates, macros, and retracts. This isn’t just visualization; it’s verification of real machine behavior.

🛰 MANUSsim Optimize Optimization shouldn’t be guesswork. With a single click, MANUSsim Optimize analyzes real NC programs to eliminate inefficiencies, reduce air cuts, accelerate cutting feedrates, and turn wasted motion into measurable time and cost savings. The result is faster machining without compromising safety or quality.

More than optimization—a mindset change

This isn’t about one country, one shop, or one role. It’s about raising the baseline for CNC manufacturing everywhere. When G-code is transparent, verifiable, and optimizable, teams stop firefighting and start improving.

And this is only the beginning.

We’re actively working on new innovations that will push CNC post-processing, simulation, and optimization even further—designed to be ready, inclusive, and impactful from day one.

Follow along. The future of G-code is moving fast.

❤️ We love G-code optimization. Do you?
