Detect CNC collisions before they happen.

Don't rely on dry runs. Simulate your G-code on a 3D digital twin.
Catch spindle crashes, tool holder interference, and fixture hits instantly.

What is CNC collision detection software? It is a tool that analyzes your post-processed G-code against a full 3D model of your machine, tools, and fixtures to identify any physical interference. With Eureka3X, advanced CNC collision detection ensures your setups are safe and your programs are crash-free.

Trusted by professionals who can't afford mistakes

Eureka3X is built on Eureka Virtual Machining — 20+ years of industrial CNC simulation, used in production by world-class manufacturers.

Sound familiar?

These happen every week in every shop. Eureka3X fixes all three.

THE PROBLEM

Blind rapid moves (G0)

A rapid move straight into the stock or the table is the most common and devastating cause of spindle crashes.

THE FIX

Analyze every movement

Eureka3X calculates the exact trajectory of every G0, G1, G2, and G3 move, flagging any intersection between machine components.

THE PROBLEM

Tool holder and fixture interference

The cutting tool clears the part, but the thick tool holder collides with the vise or a high wall.

THE FIX

Exact 3D tooling and fixtures

Import your exact tool assemblies and workholding. We detect collisions between any non-cutting part of the tool and the setup.

THE PROBLEM

Tool length compensation (G43) errors

Forgetting to call G43 or using the wrong H-offset causes the tool to plunge directly into the table.

THE FIX

Controller logic emulation

We simulate the controller's offset logic. If the length compensation is missing, the simulator crashes exactly like the real machine would.

The math is obvious.

A spindle crash means

Days or weeks offline
Every day of downtime erases margin
Costly machine repair
Spindle, fixture, and tooling damage
Scrapped parts and missed deliveries
Reputation damage on top of material loss

Eureka3X protects you

One crash costs more than a year of Eureka3X. Load your G-code, run the simulation, see the crash on screen — not on the machine.

Frequently Asked Questions

+Does it detect tool holder collisions?

Yes, Eureka3X checks for interference between the tool holder, the spindle, the fixtures, and the unmachined stock.

+Can it detect rapid (G0) crashes?

Absolutely. Rapid move collisions are the most common cause of machine damage, and our software flags them instantly.

+Do I need to model my own machine?

No, we include 4 production-ready machine models out of the box. You just need to import your tools and fixtures.

+What happens after the trial?

After 30 days, your trial will expire. If you want to continue using the software, you can upgrade to one of our plans. There is no automatic charge since we don't ask for your credit card upfront.
