Verify your Sinumerik cycles before they hit the real machine.

Eureka3X interprets your actual Siemens post-processor output on a complete 3D machine model.
Collisions, FRAMES errors, and complex cycle parameters — caught before Cycle Start.

What is a Siemens CNC simulator? It is specialized software that interprets the actual NC program—post-processed Siemens 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.

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

Complex CYCLE parameters

Siemens drilling and tapping cycles like CYCLE83 or CYCLE84 have many complex parameters. One wrong value leads to a scrap part.

THE FIX

Siemens-accurate simulation

Eureka3X emulates the exact behavior of Sinumerik cycles, ensuring complete fidelity to your machine's specific routines.

THE PROBLEM

FRAMES and D-offsets

TRANS, ROT, and D-offsets can cause unexpected tool positions that generic simulators won't catch, leading to crashes.

THE FIX

Controller-accurate spatial simulation

We simulate exactly how Sinumerik interprets frames and offsets based on actual controller logic.

THE PROBLEM

Post-processor output is a black box

Fusion 360 or Mastercam simulation doesn't understand Siemens-specific logic and syntax, so they can't verify the final code.

THE FIX

Simulate the actual G-code your Siemens runs

Eureka3X interprets the post-processed G-code exactly the way your Sinumerik does. No guesswork, perfect verification.

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 simulate Siemens specific cycles?

Yes, Eureka3X natively interprets Siemens CYCLE83, CYCLE84 and other specific routines exactly like the real Sinumerik control.

+Which Siemens controllers are supported?

Eureka3X supports a wide range of Siemens controllers including Sinumerik 828D and 840D series.

+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.

+Can I use my own Siemens G-code files?

Yes! The simulator is designed exactly for that. You can load any NC program post-processed for your Siemens machine and verify it using one of the included 3D machine models.
