I'll be there. Got to find a new ballooning software and browse for new stuff.

Nowhere, it's a really bad joke. Took me a while to find a good Greek name.

And I just found where the reference is, buried in some PCM that calculates a bolt circle from all related cylinders determined by bore count. See the highlighted code in the image. 🫣

I am running into this error, and I can't find the reference being referenced. Depending on the part configuration it can have from 3 cylinders (with 3 scans per cylinder) to 13 cylinders (with 3 scans per cylinder). "Circle1_Groove OD" has no visible or searchable reference to any of the "BASE_CIR_xxx" features. Same with "Circle1_Groove ID" (no error) and ""Circle1_Groove OD" was created as a copy of ""Circle1_Groove ID". Parameters shown in the reference image are numeric values from an Excel file for the Para side, there are no references to any of the "BASE_CIR_xxx" features or related characteristics. It's all PCM and Para file controlled. I do not believe the PCM controls the number of cylinders to scan for my tertiary datum, which is "BASE_CIR_DATUM -C- 2" used in the Base Alignment. All features shown in the "Base Cir features" image are not used for this mini plan. The PCM only controls where the program reads code based on the number of cylinders. The last part of code is well after the first section of code. Any assistance is appreciated. if (num_bores==9) and (miniselection=="Rough Bore Characteristics") if (tongue_inspect==1) then setRunID("9 Broach Rough Bore Characteristics") //New 12.12.23 inspPath = getActualInspectionDir()+"\" fileName = "setRunID.txt" deleteFile(inspPath+fileName) addToFile(inspPath+fileName, getRunID()) //End New else setRunID("9 Rough Bore Characteristics") //New 12.12.23 inspPath = getActualInspectionDir()+"\" fileName = "setRunID.txt" deleteFile(inspPath+fileName) addToFile(inspPath+fileName, getRunID()) //End New endif endif Except the I have this code that should bypass the above (for any number of cylinders). //New 08.27.26 Back Face Groove diameters if PN=="00-363107" miniselection=="00-363107 Grooves" setRunID("00-363107 Grooves") Machine="Groove Characteristics" //New 12.12.23 inspPath = getActualInspectionDir()+"\" fileName = "setRunID.txt" deleteFile(inspPath+fileName) addToFile(inspPath+fileName, getRunID()) spd_grv="0.29650" endif

Invest in one of these, I can set any angle quickly and easily. ZX, ZY, XY or any compound angle you can imagine. You may also need a small set of gage blocks.

In Calypso 2025 you can still apply it using Loose but there’s a reason they got rid of it.

Has anyone encountered this error when trying to do a full calibration with the ScanPort? I get this same error when it's on position 12. On the right side it says that it needs to decrease distance, but this is ScanPort automatic calibration, I don't have the option to move the sensor closer. Any guidance is appreciated.

I believe you are correct @Perry Steever2. If the basic dimensions are to planar surfaces, or to other features from planar surfaces, they're asking for TP Ø.020 to the referenced surfaces. Depending on what standard is referenced on the print you'd also get a modifier on those holes too.

If there is nothing else controlling the location of these holes I would assume the design intent is that the datums is the features that the basic values originate from. If there are other dimensions controlling the location I would assume that this is like the lower section of a composite true position. Just these two holes relative each other. I would ask the designer but he is probably retired or dead by now.

If it doesn't come out before December 31st, 2026, I want my 2026 SMA money back . That said, I'd be happy paying for 2026 and 2027 if they changed the icon's back or at least improved them. Especially the ID/OD icon, because who hasn't misinterpreted the small black circle feature icon and crapped their pants when it outside the hole to measure it?

@Tom Oakes, nice job on using the CMM to measure your stylus system angles. You should ditch the aluminum extensions, though. The CFX extensions are a worthy upgrade.

The 1970's are calling. Is this just a TP Ø.020? I dont have any datums, but I do have some basic locations of these hole locations.

@JeffI have created the macro, but I didn't use it much. But that's not entirely true. I did a bunch of testing years ago and the difference between the macro and default concentricity wasn't very much. Not for my parts at least. I'm sure there's some parts where it would make a significant difference, but I'd do the testing before I committed to doing the crazy macro all the time. On the bright side, ASME 14.5 did me a favor and obsoleted concentricity.

Haha I wouldn't go as far as GOAT status but thanks for the kind words, I'm always happy to help!

@Chad Watton, thanks for sharing this PDF and the root cause of projection error in Calypso's concentricity characteristic. Since this PDF was presented during a live Lunch-and-Learn, there are some gaps in the how-to. How do you deal with concentricity in Calypso? Have you created a macro similar to the one described in the PDF?

I've used this and a sine vise to set all of my angles for years now and it works perfectly. Everything is within about .00015" perp and parallel. If you have the opportunity to have one made, I can send you the .stp file? It would save a lot of time setting up stylus systems in the future but doesn't immediately address the issue at hand.

Thank you! I figured it had something to do with it skewing one of the holes and projecting it over the distance between them. I tried what was suggested and got .2mm one direction and .1mm the other direction.

You're almost certainly getting projection error caused by trying to measure concentricity across a distance. A small error on one side is projecting to a much larger error on the other side of the part. I've posted this several times on the forum, but its worth a read if you haven't read it yet. Concentricity across a distance starts about halfway down the PDF. Something like this. Profile_Concentricity_CALYPSO.pdf

If you are using gage, then scan it like one cylinder and use outer tangential. Due to undefined drawing can not tell more.

I getting what I feel are unrealistic results when measuring the concentricity between holes on two plates on a weldment. Callout on one hole is .5mm to the other hole. No other datums. Functional gage passes thru both holes on all pieces, but the CMM is giving a result of 1.2mm to 6mm (wow). I need help figuring out of there is something I am doing that is causing it to skew. Don't judge my terrible drawing skills. I don't have the parts anymore and will not post the drawing, but you get the idea. Basically there is a bottom plate, with a plate perpendicular to the bottom plate on each end. There is a hole in each of the side plates. For my alignment, I used the top side of the bottom plate as my Z and spatial. I made a line across the front side of the bottom plate for Y and planar. I took a point on the outside of the left plate for my X. Information that may or may not be helpful: The left and right plates are perpendicular to each other within .1mm. I first probed them as circles and asked for concentricity. I then probed them as cylinders and asked for coaxiality. The holes are laser cut and sort of rough. Every time I probe them as a cylinder, it thinks its a cone or sphere, and I have to change it to a cylinder. I tried changing from the default ISO to Loose and in some cases, that made it worse. I tried changing the alignment to use the left plate instead of just the single point. I tried plugging additional datums into the characteristics. I tried using a straight down probe with the RDS XXT at 90 and I also tried using a star probe. I cannot get any of the pieces to give a concentricity or coaxiality results below 1.2mm. I don't have the parts anymore, as my manager stated we would send them on the basis that the functional gage passes. I would just like to know what I should do differently in the future.

Well you wrote you are measuring those cylindrical pins against probe to get angle. When i was doing angle i was loosening a screw to adjust angle around Z axis. Then i was measuring with probe shaft the ref. sphere so from measured points i got cylinder - this way i got angle in Z axis and also tilt. What was confusing for you? Definition how to measure adapter pins?

Yes, indeed

@Keith Forche Does this also apply to rotations about the center axis?

IDK... to be honest, 95% of the time I set the angles of the probe visually, with a printed out chart.
