Actual points not perpendicular to Surface

[[Ke...]]

Good afternoon everyone,
I have a Crazy Duramax that was running great 5 days ago, now the operator is getting bad parts. I look at Data and see the points are NOT perpendicular to the surface (Photos attached). So I did the following with a known Good Master part.
1. Check the Fixture, it was tight and square to the table.
2. Probes are clean and tight
3. Re qualified probes
4. load part, made sure it was seated properly
5. Manually pick up Base Alignment
Still got Skewed results......So I shut everything down for 15 mins than did steps 1 thru 5 again still got bad results.
Are all Duramax's this finicky??? I also got an Weight error for my Master probe to add to the mix.

Something else could be going on, but I've only seen this with star probes. It's a weight/balance issue.

The probes seem to be the same probes when I left. I wonder if the operators crashed it didn't tell anyone. Thanks for the idea I'm going to double check the probes to make sure there the sames as before.

Take a look at the status window for crashes. Also, If you don't have it, I would recommend getting CMM
observer. Just be advised in advance that the machines firmware must be up to date for it to work properly.

We had the same issue 4 months ago. Turned out the spring was broken in the Vast XXT TL1 probe head. Had a tech come out removed the head, gently shook it and the noise you could hear was what he called the "death rattle". Very expensive replacement. Cannot remember if it was $3000.00 or $5000.00 for head exchange price.
Good Luck

A new XXT is around $6,000

The Duramax came with another head? Is there any diagnostics tools built into calypso, I know Zeiss tech have a program.
Anyone have a guide to changing it out? is it similar to a vast XT switch it out and just requalify all probes?

Shut down Calypso, unscrew the XXT and install the new
one. You may have to go to the Zeiss portal (You'll have to
register if you haven't already) and download the device
activator. Re-boot Calypso and requalify probes.

In my opinion, those point angles are pretty normal for a star probe on an XXT sensor.

Yep, that was my original response. Even though the visual is bad, results are good.

Thank you for all your help and response, but I'm puzzled that the Master part checks bad on this Duramax and good on the other. I'm going to change the head tonight after 1st shift leaves and see if this fixes the results.

Has this exact issue with our Duramax with XXT right out of the box and was told it was normal. Notice that the stylus actually pivots/tilts on an XXT as opposed to traversing like an XT head does. I'm pretty sure this isn't the problem.

We get angled vectors with our XXT / RDS setup all the time, when using star styli. Tech support and even the infamous Ryan Stauffer said it was pretty normal with passive scanning and star styli. Your form error and Sigma values will tell the true tale.

I am having the same issue, not only with the vectors, but results from the Contura to the O-inspect machines. The Contura has the XT and the O-inspect does not. Machines are not correlating, I am using the same routine that was written for the Contura. I did not write the program, second day at this company and have been tasked with figuring it out. When I wrote a quick sanity check program using a 1,2,3 block. Got different results using the star probe compared to a down probe (.100mm), with similar looking vectors as far as pointing up or down in the Z axis. All of the down probe's vectors, as well as probe 2&4 (front and back) were parallel or perpendicular.
I've lightened the stylus by creating a T-Probe , instead of a star and am still not seeing a difference. I've powered it all down and re-Qualified everything, several times with no remedy. Can anyone shed some, additional, light on this? I'm stumped.
