Hello all,

I'm from the Romanian reseller of SprutCAM.

These days I have to deal with a MAHO 800C machine with a Heidenhain TNC control. I have no ideea what kind of TNC it is because the owner didn't have any manuals at all.

I tried to run some tests in order to figure out how the controller works (linear, circular interpolation) but the owner didn't allow me to stop its production more than 20 mins (he has some hard production dealines to meet).

So, the conclusion is:
- it is like a TNC 151, but the circular interpolation does not work like that
- the closest post-processor from SprutCAM its the MahoHem232, but there are some differences (the main one is that MahoHem232 uses X Z instead of X Y axes, but that is easy to modify).

After this long introduction, here comes my cry for help smile.gif

Does anybody worked with this machine and developed a post-processor for it ?

Of course, I'm ready to start working to develop a new one, but hopefully someone just did that before.

Thanks in advance.

Hi Dave,

Thanks for your help.

However, the main problem consists in the way the fixed cycles are programmed.

The fixed cycles are defined in the same way as in the post processor you sent me, but they are called in a different way. For exemple, for drilling two holes, the sequence is:

cycle definition

LBL 1 (start underprogram)
position above the first hole and calling the cycle (M99)
LBL 0 (finish subprogram

LBL 2 (start underprogram)
position above the second hole and calling the cycle (M99)
LBL 0 (finish underprogram)

Do you have ever seen a SprutCAM post-processor with that facility ?

However, if there isn't such a post-processor, I believe the cycles may also be called without using underprograms. I have to check that.

Anyway, thanks again for your help.

Radu
