Hallo Herr Kessler, Vorab danke für Ihre Antwort. Das Basissystem steht bereits (Raumausrichtung+ XYZ Null). Das einzige was ich benötige ist eine Rotatorische Begrenzung da ich entlang der Z-Achse eine Linienprofilmessung machen muss. Sobald die Spindel ein wenig verdreht ist, passen die Profilmessungen ebenfalls nicht mehr.

Hallo Paul prinzipiell ist es nicht nowendig die Helix für die Messung rotatorisch auszurichten. Über selbstzentrierende Kreismessungen unten und oben kann ein Basissystem des Gewindes erstellt werden. Der Z-Wert einer selbstzentrierenden Antastung in -X liefert mit Versatz in Z-Richtung definiert den Ort in Z. Anschließend erfolgt die gesamte Messung des Gewindes und die Achse des Helix-Zylinders ergibt die neue Z-Achse des Helix-Koordinatensystems, das als Basis für die Gesamtsteigung und den gesamten radialen Verlauf des Gewindes dient. Zwei Randbedingungen kann ich der Anfrage nicht entnehmen: 1. Gibt es eine Bezug in der Zeichnung für die Z-Lage des Gewindes? z.B. Ebene oben, seitliche Gerade bzw. Index-Bohrung 2. Ungünstiges Verhältnis Gewindedurchmesser zu Gewinde? Ist dieses der Fall sollte Auswertung die Einzelsteigung und der Gewindedurchmesser in lokalen Koordinatensystemen erfolgen, die der Biegung folgen und damit den Exzenter-Fehler berücksichtigen. 3. Erfolgt die Messung mit Drehtisch oder aufgrund der Länge liegend (z.B. Y-Richtung)? Alles ist möglich, wobei der Aufwand entsprechend der Spezifikation zunimmt. Hilfreich für eine detailiertere Antwort ist die Zeichnung, da die notwendigen Angaben meist nicht Inhalt des CAD Modells sind. Diese ist hilfreich für die Visualisierung. Gruß Klaus 45.pdf

Moved to CALYPSO\General

Changing those parameters did not work for me at the time. But I haven't tried it in the latest version of the software.

your milage may vary depending on the version of CALYPSO you're using, but once you right click > export, you can select a specific alignment. at least that's the case in CALYPSO 2025

I have been able to get the sensor I am using recognized by the software and the software will connect to it. I can not initialize the sensor however because when I try to it wants me to update the configuration in the setup. This makes sense since the lens setup and calibration need to be done. The problem is when I try to go the setup tab it crashes every time. I am unsure of what the cause is because I have confirmed that I have the up to date software and drivers installed. I also have a graphics card that the system has said fit the requirements. The sensor status is checking green and I have run through the web interface as well and the sensor again shows no problem. This all leads me to believe that this is a software issue rather then a hardware issue but I am unsure how to fix it. Thank you, Sam

It's been a minute, but last time I tried to export points from a point cloud it was always relative to the base alignment. Just a heads up.

@Richard Stanich Features - Special - Point Cloud - Recall feature points of all features you want to export - right click on Point Set and export points.

Thank you all for the input. Once I can some free time on one of t our Duramax machines I'm going to work through these suggestions. Getting free un-interrupted time on a CMM is probably gonna be more difficult than adding more reporting data to the qualification program. Ha! I'll report back to this when I get some of this done.

Ok, then how do I create a point cloud of measurement data?

I don't think this is possible via curves - at least i did not test this, i am using free form, which would be more suitable. Or you would need to scan a few hills to bestfit in Z axis - you will obtain Z value from which can be rotation calculated ( via given helix angle )

Thanks for the replies, I tried Chrome and got in. Oddly enough I've been able to access the forum using Edge.

Hello David If you still are having issue logging in to portal and have active SMA, call our hotline +1 800 327-9735, and they can make a ticket for you to help you with your account

Correct - and the DXF export is only for Curve features.

Here's an article on the topic which goes a little more in depth. https://portal.zeiss.com/knowledge-base?id=3366611

I’ve found going strictly by the values Calypso gives you immediately after the requalification aren't reliable if you’re looking at part tolerance windows of anything less than +/- 0.001” (.0254mm). Here’s my experience. For every program I write, I also write a probe qualification program for whatever probe tips are used within the part program. The probe qualification program sets the X, Y, & Z origins of the artifact to “0”. I have the program go through and qualify all the tips first (so there’s always a minimum of at least two physical probe changes), then it goes back through and grabs each tip (even the master probe) and re-probes the artifact to see if the tip is still seeing the location and size of the artifact are still at “0”, “0”, “0” and 30mm Ø (or whatever size artifact I’m using). Reasonably often I’ll see results significantly different than the “0”, “0”, “0” and 30mm Ø that I was expecting. There are a few reasons that can cause this, but regardless the differences will still pop up at least once a week. If I wasn’t checking for this, or if I was only going by numbers Calypso gives me on the qualification page, I’d be introducing measurement error and wouldn’t even know it - I would be thinking it was the manufacturing process that wasn’t stable. From time to time I even find the master probe gets a bad qualification.

Hello @David Carr, have you tried another Browser? Even internally we often had issues caused by the Browser. Best Regards Marcel

Here is quick little document I created, please remember that you can select run from the tool bar, drop down menu and F8 on the joystick Rev is in honor of the student who lost it and is kind of a joke because he was an old co-worker that I can now bust his chops 🙂 Missing Run Button Rev Wade 01.pdf

Hi David, no, I just loged in.

Is anybody else having an issue logging into the Zeiss Portal? Haven't been able to log in for a couple weeks.

Hallo zusammen, ich möchte eine Kugelgewindespindel in Zeiss Calypso messen. Dafür muss die Spindel vor der eigentlichen Messung korrekt eingedreht werden. Ich habe gehört, dass man dafür einen Teil der Helix messen und anschließend einen Bestfit erstellen kann, bei dem nur die Rotation um die Spindelachse (C-Achse) freigegeben wird. Die Translationen X, Y und Z sowie die Rotationen um X und Y sollen dabei gesperrt bleiben, sodass lediglich die Verdrehung der Spindel bestimmt wird. Leider ist mir nicht klar, wie man das in Calypso Schritt für Schritt umsetzt. Meine Fragen sind: Wie erstelle ich daraus einen Bestfit, bei dem ausschließlich die Rotation um die Spindelachse freigegeben ist? Welche Einstellungen muss ich im Bestfit bzw. in der Ausrichtung vornehmen? Ein CAD-Modell sowie das Curve-Modul sind vorhanden. Falls jemand diesen Ablauf bereits umgesetzt hat oder ein Beispielprogramm bzw. eine kurze Anleitung hat, würde ich mich sehr darüber freuen. Vielen Dank!

I believe an element needs to be tied to characteristic for CNC export.

I use Red Cratex, sometimes Brown. You can rub or spin the sphere on the Cratex, it will clean it quite well. I examine the spheres under 7x and 10x. I have been doing this for about 18+ years extending the life of styli 10x in most diameters (1mm is difficult due to breakage). Do not spin the Cratex with a motorized device, spin the stylus instead by hand or motorized device at slow rpms.

I am trying to create a DXf file of points for a customer; I have not worked with this option before. I should be creating a folder with dxf files, it isn't working. The last image is an example of what is required in simplest terms. What do I have wrong or don't have setup?
