there should be a initialize sensor button near the top right that should fix that i think

For some reason the buttons on my scanner are not working. I have re-started and unplugged the scanner. Still no use of the controls on the devise. What am I missing. Is there a toggle or an on/off button I'm missing?

What about using fixturing to physically clock the geometry? This would allow for an alignment on one of the lands. I would think this would allow you to scan only the surfaces you needed. We do something very similar here. Physically clocking some very complex geometry so we can avoid certain surfaces to measure Datum circles.

How about using maximum/minimum coordinate on your scanned circle to find the high/low spots. Then use that info to refine subsequent alignments.

Most of it only with PCM to have a comfort. For others you have to do much of a work by copying features and so on. I would recommend using base alignment to have iterative result and better / safer definitions of nominal paths / points to scan.

I’m looking for input from anyone who has implemented an iterative bore-measurement approach in Calypso 2022 that isolates the lands only when establishing a datum from a rifled barrel. On our previous Hexagon CMMs (PC-DMIS, non-scanning), we established the primary datum feature from the lands by measuring a 4-point circle. After the initial measurement, we used an IF/THEN routine: If the measured diameter fell outside a defined range (indicating contact on grooves), the alignment would rotate by a set increment. The circle would then be remeasured. This loop continued until all four contact points landed only on the lands. That resulting circle defined the bore diameter. We repeated the process at the opposite end of the barrel and constructed the datum axis from those two circles. With our Zeiss machines, we’re currently scanning and using a maximum inscribed circle to define the bore. While this works, I’m interested in recreating something closer to the iterative “land-only” approach described above—ideally using Calypso logic, PCM, or another built-in method. Has anyone done something similar in Calypso 2022? Specifically: Rotating an alignment iteratively based on measured diameter feedback Forcing point selection to land features only Or scripting a looped remeasurement routine to converge on a land-derived circle Any guidance, examples, or best-practice suggestions would be greatly appreciated.

You touch a single point and then the system automatically probes points. It starts with three points on the angled surface, then a point in the -Y axis and another in the -X axis for each probe holder. The angled plane can now create intersections based on the other two points; each separate point can be theoretically a plane. This combined can create an intersection of the corner of the probe holder which can be translated to the center of the probe holder. (My best theory).

Chances are the locking mechanism, which is plastic, became deformed, most likely by attaching the sensor without using the little black button on the side. I have repaired many of these by hand, but at some time you will need a replacement part, and I am not sure if Zeiss sells just the locking mechanism.

Agreed and forced are two separate actions. I use the word forced because you have no other choice.

Hi @Denis Shlevits Welcome to the forums, and thanks for sharing about your Calypso learning journey. The suggestions already offered in this post are terrific. Additionally, here is a resource for web and video based Zeiss Calypso CMM learning: https://www.victoryprogramming.com/ My friend Steven Devowe owns this business and is an excellent teacher. The training courses have a cost, but there are also a number of free resources on that website. Also, Zeiss provides outstanding training, so perhaps your company would be willing to send you. They have in-person (my preferred method), Live-Online, and Self-Paced versions of training: Zeiss Training Formats Feel free to ask questions on this forum whenever they arise or DM anytime.

Yes, the angle is going to throw off where that Y value is. The Y value will come from the origin of the plane feature, it wont necessarily be on any one of those points or an average of all of those points. With the feature window open, you will see a light tetrahedron. This will show you where that Y value is calculating. Because there is an angle on the plane, that may be above or below where you calculate the average since it will be in the corner of the plane rather than the center.

I don't know what purpose has Datum2, but avoiding it is helping. But if you need that point to set your origin, then i am out of ideas how to enable MMR on that single plane. Point / intersection with plane and cylinder to get a point is not working also. I understand why it needs MMR on all elements, but not sure how to enable that on single plane.

XYZ Architect on YouTube is another very knowledgeable person. I have watched a lot of his videos are very helpful.

No I am meaning to remove the XXT from the RDS but it wouldn't come off, you know you release the probe and on the XXT it releases the XXT sensor itself and you have to press the little black tab it and it just comes right off. Mine is stuck.

Yes it is still a problem...see below. Datum B is a plane and cannot have a MMB material requirement. I also don't like that you must use GDT(ASME or ISO) to measure the datum features. We use Guassian/Least Squares often from years of correlation with other methods like CMM/Vision, and also, surface quality of the mesh comes into big play when you use tangent(exterior highs) for features. It would be like taking 7 hit points on a plane on a CMM and constructing a tangent plane...you don't know if you actually hit enough of the plane to capture the highs. So sometimes it is prefered to use least squares.

This is still an issue with Zeiss Inspect 2026.

As relates to CT, what cathode warm up procedures do you do? Do you use the X-COM utility (conditioning) or rely on the Zeiss Quality Suite overlay?

@Nacu_Tu_Wien_IFT I am not sure I am following exactly what you are trying to do, but after creating the "CAD" you align the volume to the "CAD" by doing an initial alignment>prealignment (volume).

I second this. Their videos are easy to follow and they explain really well.

If you are talking about removing the probe from the XXT, do not select " release probe. Just firmly grab the shaft of the probe and tip/pull it towards you at an angle. That will release the magnet. Pulling straight down does feel like it would damage something inside of the XXT.

@Federico Ciammetti You have to have a license of Calypso Planner. Then you will have access to the Planner - Simulation dropdown.

I've tested and if you want to measure perpendicular from CylinderA to CrankLine, then make a point from a line -> select Crank line -> select which point you want. Now just make perpendicular distance -> select point -> select CylinderA -> now report your YZ - this should be your value ( or XYZ to get 3d distance )

@Richard ShomakerHow can I open this window for control simulation?"

Es gibt keine direkte Funktion einen Flächenabstand so darzustellen. Man könnte die Werte in Abweichungsfähnchen über einen Ausdruck berechnen und darüber auf Prozent umrechnen. Die Legende bleibt aber unangetastet. Hier mit Sollwert 35: Ansonsten gibt es im Portal (ZEISS Portal) den Bereich 'My Voice', dort könnte die Anwendung als Wunsch eingetragen werden und die Entwicklung nimmt es auf. Nanno

Hi Phil, as @Cliff Gould wrote, you probably just have to update the license to 2026. Information about your current license like the entitlement ID can be found in the Suite. ZEISS Quality Tech Guide
