We cannot use MMR on datums due to this virtual condition being violated error. @Christoph Schult when I have time I will carefully go thru this error and send zeiss an email, b/c I understand what you are saying, but I don't think something is correct. Now, there is another real issue that needs to be fixed regarding MMR on datums in Zeiss Inspect and that is that all subsequent datums must have MMR used. Even if the last datum is a plane like you would place the part on a surface plate. You cannot have MMR on a surface plate.

Sorry Chris, I must have had a case of the Mondays. This setting is literally defined on the next tab under 'crowning' and can define the start/end high points for the desired range.

Somewhat, in the example shown its a refinement, the total deviation is allowed to be .015, but allowed to float within the .025 total band. In some other case dynamic profile will affect the shape of the tolerance zone, might be held narrower at the ends and allowed to be larger in the middle portion. I haven't done much with Dynamic Profile in Calypso, but will look into it. Possible that the function isn't currently available in Calypso 2025, but I'm not sure as i haven't checked.

I haven't been able to test this, but I was thinking that dynamic profile should be the difference between MAX and MIN from Profile bilateral two results.

Thank you all for the replies! I use a different software package from another CMM manufacturer. There these two evaluations are straightforward. Our supplier uses Calypso and tells us the missing sections make this impossible, which surprises me. Could someone confirm that grouping the circle paths into one feature allows both evaluations in Calypso? I'd be very grateful!

This isn't a bad idea. I will have to play with this. Zeiss should make this an option in Calypso. Dynamic profile was released in ASME 14.5 2018. So its fairly new. But I see a lot more designers getting interested in using dynamic profiles and I suspect we'll all be seeing this more often. Get ready folks.

- I believe that someone said that grouping the circle paths together (in the strategy window) will allow 2 point diameter evaluation (I have not tested it, myself) - manually changing from Minimum Zone to LSQ should be pretty straightforward

@Randawgg I think author knows how to measure that, but I think you can not use TP callout like Envelope to calculate min/max. And reporting just diameter is not the same like LP

Theoretically you can calculate an diameter and based on it's dimension you can set profile tolerance offset. Unless ZEISS will make this option inside Calypso.

You just need to make circle path segments at 30° angle range, then change the start angle for each section by 90°. There is a LOT of different ways to do this. A basic general gist in the image below.

This is where I'm having a brain fart. How can I tell Calypso to allow my tolerance to zone to expand or contract based on the size of the feature? "This tolerance zone may expand or contract while controlling the form, orientation, and location of the feature within the 0.15 tolerance zone, allowing the size of the feature to uniformly progress. The actual feature shall simultaneously be within both tolerance zones."

I got it. I got the cookbook! See you just have to ask nicely. lol

Zoom Level? Do you mean magnification? Isn't that the same for whatever character you select? I don't see anything that's not the same when I select the different characteristics. The curve magnification is the same when I select different features too.

Has anyone programmed a dynamic profile from ASME 14.5 2018? How do you program the bottom refinement portion which contains the dynamic profile? For example, I have a hex nut where I want the hex OD to be very concentric to the threaded ID. The size isn't that important, but orientation is.

Whatever you constrain you are telling Calypso that it's perfectly that..... So if you constrain the 45° face angle you are telling Calypso to report nominal number regardless of what it actually measures..........I was saying that if you capture top face in Alignment 1 and 45° face in Alignment 2 and you constrain both of them and measuring the angle between the two features you are realistically measuring the angle difference between the two alignments, and not the faces you selected.

Ok thanks all. I typically clean the Machine ways if this pops up. I read the Knowledge base and after no luck for an hour, saw that I should try to slow down the machine speed at Homing from a 2023 post. That worked. Did full reboots and shutdowns 3 times prior too.

Hello, we have a knowledge base article with steps on how to fix this error

Hello, You have a controller / hardware issue. Clean the machine ways. if the problem persists, please contact Zeiss Hardware support.

Hello everyone, Our supplier needs to measure a cylinder with four sections milled away: The remaining arcs are about 30° wide and spaced 90° apart, so there should always be opposing points. We want each arc scanned with high point density and the points combined into one circle. From that circle we want to evaluate: - the two-point size (LP)(SX)/(LP)(SN) - LSQ-roundness (least squares not minimum zone) The supplier says neither can be evaluated because the circle is incomplete. Can Calypso do this or not? Could someone point me to a setup or example I can pass on to the supplier? Thanks for any advice!

I wish Zeiss provided more guidance for this. It is very time consuming to experimentally derive, and there is precious little documentation that covers the effects of changing probing force.

@Norbert Bendl THANK YOU! It felt like my program would get "corrupted". This works! Thank you!

Thanks. I think you are very close to the edges - tolerance for that chamfer is still .005? I would scan at least .004 from theoretical edge and only after some bestfit for that area.

Has anyone seen this, It has been happening... ALOT. Typically after the machine has been shut down fully. It gets to the Homing, The Z drives up, the machine travels back while the X travels to the left... once it hits about 75% of the way to the Machine home, it trips out. I have yet to figure out why because it then randomly just doesn't error out. Its sporadic.

This works in calypso, you just have to be /incredibly/ delicate about slipping the probe off.
