Heidenhain Post iTNC530 TNC640 Manual NC Output

[Koch612]

Hello,

I'm looking for somebody who has implemented the direct NC Output for example for tool break control or Start Stop Chip Conveyor on a Heidenhain iTNC530 TNC640 post. I have tried to implement it by myself but it didn't work. Could somebody who has done it please share the post or just the important lines of the post so I can take a look and implement it in my post?

Hi

For the chip conveyor, search the post for 

COMMAND_START_CHIP_TRANSPORT:

Then you can add  the Mcodes to turn it on and off there

which would look like this for M41 to turn on and M42 to turn off

Tool break control can be added to the same section under 

COMMAND_BREAK_CONTROL:

depending on what probing cycles you machine uses(Heidenhain or Blum or other) this will need to be customized to suit your machine.

With the Heidenhain cycles you would need to check the tool and have some logic to determine if its broken and what to do next.
