Anyone who wants manuals for the Heidenhain TNC you can find them on their website, both in German and English.

English

Especially owners of the Interact 412's.

My 412 needs help. Aparently they made several versions of the 412. Mine won't start. I've tried everything I've read here and there too.

I didn't realize they had them online.

Nice Job Dr. Heidenhain!
