Eureka3X interprets your actual Heidenhain post-processor output on a complete 3D machine model.
Collisions, TOOL CALL errors, and complex spatial transformations — caught before Cycle Start.
What is a Heidenhain CNC simulator? It is specialized software that interprets the actual NC program—post-processed Heidenhain Klartext—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.
These happen every week in every shop. Eureka3X fixes all three.
Heidenhain Klartext and Q-parameter logic are often black boxes for generic simulators, leaving your programs unverified.
Eureka3X emulates the exact behavior of the TNC controller, interpreting Klartext and Q-parameters flawlessly.
Incorrect TOOL CALL or TOOL DEF parameters can cause tool length crashes that are difficult to predict without physical dry runs.
We simulate exactly how the TNC manages tool definitions, changes, and compensations, catching setup errors instantly.
Spatial transformations like PLANE SPATIAL or CYCL DEF 7 can cause unexpected axis movements and crashes.
Eureka3X interprets spatial functions exactly like your Heidenhain controller, ensuring your 5-axis movements are safe.
No credit card · Windows 10/11 · 4 machines included
Online tools are fine for checking toolpath direction. Eureka3X is for people who run real programs on real machines.
Every day of downtime erases margin
Spindle, fixture, and tooling damage
Reputation damage on top of material loss
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.
30-day free trial · no credit card required
The same Heidenhain programs you send to the machine. Interpreted the same way. No rewriting, no approximations.
Yes, Eureka3X natively interprets Heidenhain Klartext conversational programming and Q-parameters.
Eureka3X supports a wide range of Heidenhain controllers including TNC 320, 530, and 640.
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.
Yes! The simulator is designed exactly for that. You can load any NC program post-processed for your Heidenhain machine and verify it using one of the included 3D machine models.
