New member from Germany - CNC retrofit of a Leinen FM1

Here two pictures of the PCB board, which receives all the signals from the Heidenhain TNC113.

Clearly a prototype and it would be extremely difficult to perform a re-engineering and create the circuit diagram.

Is it this one?

Which claims that it might be the only one?

The circuit board is odd, in that it seems to have only one connection.

Do you have any pictures of the inside of the control cabinet? I would not be surprised to find that you already own some EXE units, in that cabinet.

Service Manual for the TNC113:

As far as I'm aware the glassscales directly plug into the TNC113. I rather doubt that you are going to find any EXE units in there.

Hi Andy,
yes it is that machine, It is not the only machine, it is the only prototype of the NC version..

My information is, that over serveral years less than a total of 20 units of all versions were built and sold.
There were 3 versions available
- a manual version (can be seen on on lathes.co.uk)
- a NC version like mine with combined servo-drives and handwheels
- a CNC version with a Siemens control,unit an without handwheels (there ios one on Ebay in Germany - can be fpund under "Prätecma")

Best regards

Wow, what a beautiful machine. In fantastic condition.

So there are separate motors on each of the axis? Should not be that difficult to retrofit LinuxCNC to it. You should be able to leave that lovely antique Heinhain control untouched, and just make up a separate LinuxCNC Controller with connectors for all the cables.

I have passed on your email address, but he says that he already reached out to you on a German forum?
