WCS Probing not accurate!!

[mikeNCNTL]

Hello Fusion people

I am having a heck of a time with the WCS probing  working all of a sudden

If I use the Renishaw macro directly, or call it from the Haas, I get one value. 

If I use the WCS probing cycle built into Fusion and probe to update WCS, I get a value that averages .01" different. 

This obviously makes for bad parts. 

Probe speed is set to 4.0156in, which matches what Renishaw is using as default. 

I am splitting across Y in this case to get my WCS.

The WCS probing cycle from Fusion is calling the Renishaw macro.  Are you using something else?  I doubt it has anything to do with Fusion because if it touches 2 points in Y axis to find the middle, it's entirely handled inside the probing macro (Renishaw).  Are you probing in the exact same location with the various methods you tried?

[mikeNCNTL]

The probing is happening withing a few .001 of the exact same location.
The part(s) have been indicated to ensure they are flat / perpendicular etc.

[DarthBane55]

ok, but the code is calling a Renishaw macro right?

Actually, do you mind posting here the 2 versions, the one you did by hand, and the code from Fusion?

[mikeNCNTL]

It is calling a macro, I will go look and see if it is calling something different shortly

Can you share your Fusion file here?

Keep in mind if you are doing a wall or Z height, that the offset in your heights tab can effect it. 

IE if you probe Z on the face, but have it programmed for -.1 by accident, it will tell the machine your top of part is actually -.100 from where it really is.

Seth, I can send you the file directly. I can't post it out in the wild. 

I can't see is the subprogram running when using fusion is the same as what runs when I probe vis VPS on the haas. 

There is not an offset to height set in fusion. This is just finding center of a feature machined in a previous operation.

Here is more info. Showing where the part is being probed, and the machine coordinate results of fusion vs Haas

G58 is probed with Haas. G59 is updated by Fusion. G154P1 is what is used to position probing in fusion. Y axis is whats screwed up.  There are reference flats cut in op 1 to probe on. This is not probing the cylinder. The flats are not tapered to one another. They are parallel.

@mikeNCNTL drop me an email with a LINK to the Fusion file (not the file itself, just the link). Right click on the file in your Data Panel and select "Share Link". Copy that link and email it to me:

Your datum point is off location, it's not at zero:
