Siemens Turning Post

[roy.haynes]

Can anyone tell me how you amend the post so that it outputs G291 at the start of every program and G290 at the end of every program as my Siemens 808d controller is set to ISO dialect and the post is for DIN dialect and all our existing programs are in ISO so we don't want to reset the controller to DIN but have found that the G291 & G290 switch the dialect used in the program without issues and time.

Hi @roy.haynes ,

I think you could modify Siemens turning postprocessor in this way.

You could insert G291 in onSection function, at line 725 :

  
  writeBlock(gFormat.format(291));

  if (properties.showNotes && hasParameter("notes")) {
    var notes = getParameter("notes");
    if (notes) {
      var lines = String(notes).split("\n");

and G290 in onSectionEnd function, at line 1530 :

function onSectionEnd() {
  writeBlock(gFormat.format(290));
  // cancel SFM mode to preserve spindle speed
  if (tool.getSpindleMode() == SPINDLE_CONSTANT_SURFACE_SPEED) {
    startSpindle(false, true, getFramePosition(currentSection.getFinalPosition()));
  }

Please test it carefully.
