Hi @Anonymous ,

I think you could modify your postprocessor in this way :

function onCommand(command) {
  switch (command) {
  case COMMAND_COOLANT_OFF:
    setCoolant(COOLANT_OFF);
    return;
  case COMMAND_COOLANT_ON:
    setCoolant(COOLANT_FLOOD);
    return;
  case COMMAND_START_SPINDLE:
    onCommand(tool.clockwise ? COMMAND_SPINDLE_CLOCKWISE : COMMAND_SPINDLE_COUNTERCLOCKWISE);
    return;
  case COMMAND_LOCK_MULTI_AXIS:
    return;
  case COMMAND_UNLOCK_MULTI_AXIS:
    return;
  case COMMAND_START_CHIP_TRANSPORT:
    writeBlock(mFormat.format(50));
    return;
  case COMMAND_STOP_CHIP_TRANSPORT:
    writeBlock(mFormat.format(51));
    return;
  case COMMAND_BREAK_CONTROL:
    return;
  case COMMAND_TOOL_MEASURE:
    return;
  }

Moreover you shoud comment every block you find both 'onCommand(COMMAND_START_CHIP_TRANSPORT); ' and 'onCommand(COMMAND_STOP_CHIP_TRANSPORT);'. E.g:

// onCommand(COMMAND_START_CHIP_TRANSPORT);

// onCommand(COMMAND_STOP_CHIP_TRANSPORT);

Please test it carefully and let me know.

Hello,

Every new operation the chip transporter is going on and at the end of every operation the chip transporter is going of.

Is it possible that the chip transporter only on / off is when i give the commend?

See the attachments for the program and the post.

Hi @Anonymous,

I think that if you comment 'onCommand(COMMAND_STOP_CHIP_TRANSPORT)' at line 795 :

    if (!isFirstSection() && properties.optionalStop) {
      //onCommand(COMMAND_STOP_CHIP_TRANSPORT);
      onCommand(COMMAND_OPTIONAL_STOP);
    }

you should have what you needed :

M50/M51 will be present only when and where you program them.

Please let me know.

Hi Tom,

It sounds like you're trying to adjust the post so the chip transport works with manual NC, but it's not functioning as expected. If it's running with M50 (on) and M51 (off), you might need to check:

Post Processor Settings – Ensure the correct M-codes are implemented in your post-processor.
Machine Compatibility – Some machines require additional parameters or logic for manual NC mode.
G-Code Customization – Try manually inserting M50/M51 in your program and see if it behaves correctly.

Could you share more details about your setup (software, machine type)? That might help in troubleshooting further.

Best regards,
Alexander Wilson
