For 3-axis milling with Fanuc or Fanuc-compatible controls (most common), the generic Fanuc GPP2 post included with E11 is a good start. It outputs basic G-code:
What it lacks (and you must add manually):
Let’s be honest—E11 is showing its age.
To avoid crashes and inefficiency, you must edit the .gpp2 source. Most useful modifications: cimatron e11
Cimatron E11 is an incremental but practical release: not a radical redesign, but a meaningful productivity boost for teams focused on mold & die and complex milling who want fewer surprises from CAM to machine.

Cimatron E11 is a bit older (released around 2013), but it is still widely used, especially for mold & die and 3-axis milling. A "useful post" for E11 depends heavily on your machine + controller (Fanuc, Heidenhain, Siemens, Mazak, etc.) and machine type (mill, mill-turn, wire EDM).

Here’s a breakdown of how to get a useful post for Cimatron E11, what works well, and common pitfalls.
One of the most talked-about features in E11 was the Quick NC environment. Programmers could define a machining process—roughing, finishing, rest roughing—and the system would automatically adjust for the stock remaining. The algorithms for High Speed Machining (HSM) were aggressive but safe, reducing air cutting significantly.
In the fast-paced world of Computer-Aided Manufacturing (CAM) and Computer-Aided Design (CAD), software versions come and go. However, few releases have left as lasting an impact on the mold, tool, and die industry as Cimatron E11. Released as a milestone version by 3D Systems (formerly Cimatron Technologies), E11 represents a pivotal moment where 3D design and 2.5-to-5-axis machining became truly seamless. What it lacks (and you must add manually):
Even years after its release, Cimatron E11 remains a benchmark for reliability, speed, and specialized functionality. For many toolmakers, it is the "gold standard" that subsequent versions are measured against. This article explores the intricate features, technical specifications, and enduring legacy of Cimatron E11.
E11 is famous for its Mold tooling capabilities.
✅ If you just need a working 3-axis Fanuc post – Start with the generic Fanuc_3axis.gpp2 that came with E11. Test on air cuts first.
✅ If you need a post for a specific machine (Haas, DMG Mori, Okuma, Heidenhain TNC) – Find a sample post online (Cimatron forum) and adapt it.
✅ If you run production – Consider upgrading to a newer Cimatron (E14/E15/E16) or using a commercial post builder. E11's post is limited for advanced cycles.
