Heidenhain TNC post processor

This is the actual opening and closing of a program Takshak posted for Heidenhain TNC — 79 lines in full. It is the same output our test suite checks on every build, not a sample written for this page.

The program frame — how the file opens, how tools are called, how it ends — is what differs between controls, so that is what you can see here. The cutting moves in between are the part.

Heidenhain TNC ships in millimetres. We have not shipped an inch variant because we will not guess the inch feed-word convention on a control we have not verified against a real reference — 17 of the other posts have one. If you run this control in inches, write to us: a real sample of code your machine is happy with is all it takes.

The Heidenhain TNC post targets the common dialect rather than one specific machine. If your control wants something slightly different, duplicate any built-in post and edit the copy — it inherits from the original and stores only your changes, so the shipped post stays intact and updates cannot overwrite your version.

Send us a short G-code sample your machine is happy with and we will tell you straight whether it matches or what would need changing: support@takshakcam.com.

The post is the last step. Before it, Takshak reads your solid, finds the machinable features, and gives you a full 3-axis operation library plus 4-axis rotary — see what it does. It runs on Windows and Linux, entirely on your own machine, and it is a one-time perpetual license, not a subscription.
