Post for Haas VF2 and multiple WCS

[Anonymous]

Hello,

I work at a job shop that is considering switching its CAD/CAM software to Fusion 360. I am familiar with solidworks and using the hsmworks cam plug in. Yesterday I ran the first parts programmed with Fusion and had some questions about editing the post.

This job has 6 total wcs. The first two are for the two pieces of raw stock that eventually get split in the right most double vise. The rest are for the now four pieces that are flipped into the middle and left most double vise. 

Overall Fusion worked ok but the major bug I found is that after every tool is done on a wcs it rapids all the way to machine z home (g91 zo  etc). I want the tool to come to a retract height and then rapid to the next wcs to begin machining again. 

For now I went through and manually deleted the g91 lines to solve the issue. 

Long story short, I think this may be fixable in the post.

Thanks for any advice,

Loren

You really wan't to be careful here, as long as work tops are the same, its all fine, but if not you'll crash.

I did something like this in my post to allow whether or not I wanted a z0

Add SafePlaneRetract to properties

properties = {
	writeMachine: true, // write machine
	writeTools: true, // writes the tools
	preloadTool: true, // preloads next tool on tool change if any
	showSequenceNumbers: false, // show sequence numbers
	sequenceNumberStart: 10, // first sequence number
	sequenceNumberIncrement: 5, // increment for sequence numbers
	sequenceNumberOnlyOnToolChange: false, // only output sequence numbers on tool change
	optionalStop: true, // optional stop
	separateWordsWithSpace: true, // specifies that the words should be separated with a white space
	useRadius: false, // specifies that arcs should be output using the radius (R word) instead of the I, J, and K words.
	useParametricFeed: false, // specifies that feed should be output using Q values
	showNotes: false, // specifies that operation notes should be output
	useG0: false, // allow G0 when moving along more than one axis
	useG28: false, // specifies that G28 should be used instead of G53
	useSubroutines: false, // specifies that subroutines should be generated
	useG187: false, // use G187 to set smoothing on the machine
	homePositionCenter: true, // moves the part in X in center of the door at end of program (ONLY WORKS IF THE TABLE IS MOVING)
	optionallyMeasureTools: false, // cycle through each tool used at the beginning of the program when block delete is turned off - this allows the      operator to easily measure all tools before they are used for the first run of the program
	BetweenZ: 1.0,
	WorkOffsetCount: 0,
	SafePlaneRetract: false,
	Finish_G53_X_Pos: -15,
	StopAtOffset: 9,
	StopAfterSection: -1,
	//WorkOffsetBase: 0,
	MinimumG187: 0.010,
	G187Ratio: 2,
	G187ResetVal: 0.0004,
	G1RapidG187: 0.100,
	BeepOnDone: true,
	SpiralArcSections: 16,
	LoadStartToolOnEnd: true,
	TimeStartEnd: true,
	PartsCounter: 1
};

function onSection() {
	var forceToolAndRetract = optionalSection && !currentSection.isOptional();
	var IsRigidTapping = false;
	var IsProbing = false;
	optionalSection = currentSection.isOptional();
	var insertToolCall = isFirstSection() ||
			  currentSection.getForceToolChange && currentSection.getForceToolChange() ||
			  (tool.number != getPreviousSection().getTool().number);

	var retracted = false; // specifies that the tool has been retracted to the safe plane
	var newWorkOffset = isFirstSection() ||
			  (getPreviousSection().workOffset != currentSection.workOffset); // work offset changes
	var newWorkPlane = isFirstSection() ||
			  !isSameDirection(getPreviousSection().getGlobalFinalToolAxis(), currentSection.getGlobalInitialToolAxis());
	if (insertToolCall || newWorkOffset || newWorkPlane) {

		// stop spindle before retract during tool change
		if (insertToolCall && !isFirstSection()) {
			//onCommand(COMMAND_STOP_SPINDLE);
		}

		// retract to safe plane
		retracted = true;
		if (!properties.SafePlaneRetract) {

		} else if (properties.useG28) {
			writeBlock(gFormat.format(28), gAbsIncModal.format(91), "Z" + xyzFormat.format(0));
		} else {
			if (newWorkOffset || newWorkPlane) {
				gMotionModal.reset();
				writeBlock(gAbsIncModal.format(90), gFormat.format(53), gMotionModal.format(0), "Z" + xyzFormat.format(0),"(Safe Z)");
			}
		}
		writeBlock(gAbsIncModal.format(90));
		zOutput.reset();

Thanks for the response. I'm still learning how to edit post processors and was not able to get your solution to work. There were some syntax errors but I think those were fixed and it still wasn't working. Where should the second batch of text you attached be inserted into my Post?

Cheers,

Loren

Find the funtion OnSection() its on the top of that code to show where its at.

Awesome, 

The generated code looks alot better. I will try to run it. Thanks again for the help.

Cheers,

Hi

Would this post be available to us here on the forum? I could  definitely use this.

Thanks

Everything is there, just modify your existing post as shown.  Unless things have changed a bunch, as the original post I modified is a year old or so.
