preposition befor Traori

[iros102]

I'm having issues with the standard Fusion 360  postprocessor Sinumerik 840D (siemens-840D inspection.cps) for our DMU80 eVo. The postprocessor has been adapted for our DMU80.

The problem is that during 5-axis machining, the machine positions itself simultaneously in all 5 axes (see video), which leads to crashes.

I want the machine to first preposition with the B and C axes, and only then execute the Traori command.

The challenge lies in the tilted B-axis of the machine.

I would greatly appreciate any assistance.

What i have:

Here is a Roundaxis vectors. That can be important.

HI @iros102 ,

Did you checked the output with setting machine configuration in setup? this will give you the ABC axis prior to TRAORI.

Kindly check and let me know the feedback.

Yes I have a customized postprocessor with machine configuration. I did not want to post it here.

But it doesn't do that either.

Here is my machine config

function defineMachine() {
  var useTCP = true;
  if (false) { // note: setup your machine here
    var bAxis = createAxis({coordinate:1, table:true, axis:[0.584968, -0.573504, 0.573504], range:[-6.5, 180.5], preference:1, tcp:useTCP});
    var cAxis = createAxis({coordinate:2, table:true, axis:[0, 0, -1], range:[0, 360], preference:0, tcp:useTCP});
    machineConfiguration = new MachineConfiguration(bAxis, cAxis);

    setMachineConfiguration(machineConfiguration);
    if (receivedMachineConfiguration) {
      warning(localize("The provided CAM machine configuration is overwritten by the postprocessor."));
      receivedMachineConfiguration = false; // CAM provided machine configuration is overwritten
    }
  }

  if (!receivedMachineConfiguration) {
    // multiaxis settings
    if (machineConfiguration.isHeadConfiguration()) {
      machineConfiguration.setVirtualTooltip(false); // translate the pivot point to the virtual tool tip for nonTCP rotary heads
    }

    // retract / reconfigure
    var performRewinds = false; // set to true to enable the rewind/reconfigure logic
    if (performRewinds) {
      machineConfiguration.enableMachineRewinds(); // enables the retract/reconfigure logic
      safeRetractDistance = (unit == IN) ? 1 : 25; // additional distance to retract out of stock, can be overridden with a property
      safeRetractFeed = (unit == IN) ? 20 : 500; // retract feed rate
      safePlungeFeed = (unit == IN) ? 10 : 250; // plunge feed rate
      machineConfiguration.setSafeRetractDistance(safeRetractDistance);
      machineConfiguration.setSafeRetractFeedrate(safeRetractFeed);
      machineConfiguration.setSafePlungeFeedrate(safePlungeFeed);
      var stockExpansion = new Vector(toPreciseUnit(0.1, IN), toPreciseUnit(0.1, IN), toPreciseUnit(0.1, IN)); // expand stock XYZ values
      machineConfiguration.setRewindStockExpansion(stockExpansion);
    }

    // multi-axis feedrates
    if (machineConfiguration.isMultiAxisConfiguration()) {
      machineConfiguration.setMultiAxisFeedrate(
        useTCP ? FEED_FPM : getProperty("useDPMFeeds") ? FEED_DPM : FEED_INVERSE_TIME,
        9999.99, // maximum output value for inverse time feed rates
        getProperty("useDPMFeeds") ? DPM_COMBINATION : INVERSE_MINUTES, // INVERSE_MINUTES/INVERSE_SECONDS or DPM_COMBINATION/DPM_STANDARD
        0.5, // tolerance to determine when the DPM feed has changed
        1.0 // ratio of rotary accuracy to linear accuracy for DPM calculations
      );
      setMachineConfiguration(machineConfiguration);
    }
    /* home positions */
	
	//
machineConfiguration.setHomePositionX(toPreciseUnit(-1, MM));
machineConfiguration.setHomePositionY(toPreciseUnit(-1, MM));
machineConfiguration.setRetractPlane(toPreciseUnit(-1, MM));
  }
}
