You can solve the problem:

First you have to watch the godfather 1-3.
Call them and say:

"I'm gonna make you an offer you can't refuse !" They will understand;-)

By the way: Der Irak hat Hochfrequenz-Gaszentrifugen für die Anreicherung von Uranhexafluorid in Deutschland gekauft - dann sollte es möglich sein eine Steuerung in Italien zu beschaffen, auch wenn man sich nicht mehr mag.

Yes, it is important - despite all the ailments - not to lose the humor!

Hello everyone!

I think I've gotten closer to the problem of denied file access. It is due to a hardware key that was connected to the printer port of the old PC. The conversion file "DXFTO0G. EXE" was protected by this. Therefore, the file conversion did not work on the other PCs. I should have known that, actually. But time has also left its mark on me, so it seems. Hope that the memory increases with the days that are getting longer again today....

Thanks for the help to all.

NUM, Switzerland will offer me a new NC for the old machines. Another factor is the post processor for the machine.
I saw at googling that there is a connection to Moi3D, namely:

https://www.filou.de/produkte/rhino-cam-plugin-madcam/
https://www.filou.de/madcam-5-versions-vergleich/

Does anyone already have experience with this software, and is it really suitable for real 5-axis milling?
Is there also a way to create the post processor?

So the problem was a Parallel port Dongle?

Re MadCam: I've no experience with it. From the English version: 30 day evaluation, cheapest 3axis version 795 euro, more for advanced versions, up to 4,995 euro, requires Rhino, version (5, 6 likely?), update last October. Have read that there are No maintenance fees.

<So the problem was a Parallel port Dongle?>

Yes, I've forgotten over the years that there is something additional behind the old PC, Dongle is the right expression.
For the developer of the software it would probably only have been 1 second to think about it, to draw my attention to it.
But that's the way of security to lose customers.
The opposite is Michael and many of these forum users, I'm glad this is so.

Thanks for the tip, I'll follow every lead from now on.

Have a nice day
Franz

Happy New Year, and THANK YOU for the quick help in case of questions!
