Does your G-code have a problem? Find out in Eureka3X, not on the machine.
Eureka3X is a G-code simulator that runs your actual NC program on a complete 3D machine model. Collisions, over-travels, and errors — caught before they cost you.
What is a G-code simulator? It is specialized software that interprets the actual NC program—post-processed 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.
💻 Windows 10/11 Required Eureka3X is a desktop simulator and cannot be installed on mobile devices. Send link to my email ➔

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
Dry runs are eating your spindle time
Every new program needs 2–3 dry runs before you trust it. That's hours of blocked machine time every week — time you can't bill.
THE FIX
Simulate in minutes, run with confidence
Verify the full program on a 3D machine model before it touches the machine. First run is the real run.
THE PROBLEM
Finding the bad block means reading 500 lines
When something behaves unexpectedly, you're in single-block mode for an hour trying to isolate the issue. It kills your afternoon.
THE FIX
Step through your program line by line on screen
The integrated debugger lets you execute block by block, inspect axis positions, and jump straight to the problem — in seconds.
THE PROBLEM
Your CAM simulator stops before the control starts
Fusion 360 simulates your toolpath before post-processing. What the controller actually receives is a different program — and a black box.
THE FIX
Simulate the actual G-code your controller runs
Eureka3X interprets post-processed G-code the way your Fanuc, Haas, or Heidenhain does. No approximations, no guesswork.

Frequently Asked Questions
+Is it really free for 30 days?
Yes. You get full access to the Eureka3X simulator for 30 days. No credit card is required to sign up or download. You can run unlimited dry runs and NC program verifications without any upfront cost, ensuring your programs are collision-free before you purchase.
+Do I need to install anything special?
Eureka3X is a standard Windows desktop application. You just need a PC running Windows 10 or 11 with a dedicated GPU (Nvidia or AMD) to ensure smooth 3D simulation performance.
+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 G-code files?
Yes! The simulator is designed exactly for that. You can load any NC program written for Fanuc, Haas, Heidenhain, or Siemens controllers and verify it using one of the included 3D machine models. This is especially useful for programs generated by CAM systems like Fusion 360, ensuring you catch post-processor errors before running the code on your actual CNC machine.
