Simulates G-code the way your Fanuc controller does — not a generic approximation.
Eureka3X interprets your actual Fanuc post-processor output on a complete 3D machine model. Collisions, rigid tapping errors, and macro mistakes — caught before Cycle Start.
What is a Fanuc CNC simulator? It is specialized software that interprets the actual NC program—post-processed Fanuc G-code—and executes it on a virtual machine model to catch collisions and errors before machining. With Eureka3X, your CNC machine simulator serves as a perfect digital twin for rigorous NC program verification.

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
Rigid tapping without M29 engaged
A tap cycle runs without rigid mode engaged. Threads strip and taps snap — and since it never physically crashes, standard collision detection never sees it.
THE FIX
Catch missing M29s before you tap
Eureka3X emulates the Fanuc control logic. If M29 is missing before G84, the simulator throws an error before you ever cut metal.
THE PROBLEM
Canned cycle behavior depends on parameters
A canned cycle packs a lot of behavior into one line. One wrong Fanuc parameter causes a crash or a scrap part, and generic simulators won't catch it.
THE FIX
Controller-accurate cycle simulation
We simulate exactly how Fanuc interprets G81, G83, G84 and G73 based on actual controller parameters, not generic approximations.
THE PROBLEM
Your post-processor output is a black box
Fusion 360 or Mastercam simulate your toolpath before post-processing. What the Fanuc controller actually receives is a different program.
THE FIX
Simulate the actual G-code your Fanuc runs
Eureka3X interprets the post-processed G-code exactly the way your Fanuc 0i or 31i does. No guesswork, just perfect verification.

Frequently Asked Questions
+Does it simulate Fanuc custom macro B?
Yes, Eureka3X natively interprets Fanuc Custom Macro B, including variables, conditional logic, and math functions, exactly like your real controller.
+Which Fanuc firmware versions are supported?
Eureka3X supports a wide range of Fanuc controllers including Fanuc 0i, 30i, 31i, and 32i series. It accurately emulates the specific behavior of these controls.
+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 (view our plans). There is no automatic charge since we don't ask for your credit card upfront.
+Can I use my own Fanuc G-code files?
Yes! The simulator is designed exactly for that. You can load any NC program post-processed for your Fanuc machine and verify it using one of the included 3D machine models.
