[Ri...] Posted October 13, 2022 Share Posted October 13, 2022 I have never tried to use a stylus pointing in the Z+ axis with an XXT head. Is this even possible? (Please be kind, I'm sensitive about my good looks). 😎Snap_001.jpg Link to comment Share on other sites More sharing options...
[Je...] Posted October 13, 2022 Share Posted October 13, 2022 . I like the glass doors in your lab, Rick. It looks like a nice space. I've qualified Z+ 45°_X+ 45° but not fully Z+. I bet a Vast could do it, but I don't know about an XXT. I double dog dare you. . Link to comment Share on other sites More sharing options...
[Ri...] Posted October 13, 2022 Author Share Posted October 13, 2022 A VAST is a no brainer... 🤣 Link to comment Share on other sites More sharing options...
[Ma...] Posted October 13, 2022 Share Posted October 13, 2022 Vast for sure as I am using one in the +Z. I'm curious why it wouldn't work with XXT??? I also don't know anything about the XXT 😉 Link to comment Share on other sites More sharing options...
[Ri...] Posted October 13, 2022 Share Posted October 13, 2022 XXT - No issues - I've done is numerous times, but try to have it balanced. RDS XXT and using CAA qualification - no. Cannot be done. Link to comment Share on other sites More sharing options...
[To...] Posted October 14, 2022 Share Posted October 14, 2022 I'm guess you're exceeding the 15 gram weight limit and maybe even the 65mm max lateral extension recommendations. Live on the edge.... Just rotate the reference sphere to the picture below. You may need to place it on a riser. Use Tilt: 90° and Rotation: 90°thumbnail_IMG_5690.jpg Link to comment Share on other sites More sharing options...

It's too tall for any other orientation though. Lol. Link to comment Share on other sites More sharing options...
[To...] Posted October 14, 2022 Share Posted October 14, 2022 In the old days, before the ref spheres were adjustable, I would mount it on a knee and it looked like a modern water faucet. In the older days, the magnetic v-block made it simple to mount on a knee. Link to comment Share on other sites More sharing options...
[Ri...] Posted October 14, 2022 Author Share Posted October 14, 2022 Tom Oaks solution worked for two articulations X+ and Y+. When I ran Y-, it stalls out at the same point every time, the last point. The X axis drive motor makes a barely audible tone and then it times out. See video, I taped the last few points when the qualification should finish and you can see it just stalls.

[Jo...] Posted October 14, 2022 Share Posted October 14, 2022 I regularly use styli qualified in Z+. We have lots of work where datums are located on the "bottom" of a part and there are features with form and location callouts back to those datums on the "top" (I especially use this method when there is a lot of material blocking navigation, such as on parts with "flange" sections) and sometimes multiple ops don't make sense, or is not possible. Granted, I've never tried a "U" shaped stylus system; mine have always been L or T configurations, with a RDS-XXT sensor setup rotated appropriately in the B axis. As a side note, I always found that qualifying probes like this didn't work so well when the sphere is tilted to 90° if the probe shank is 50mm or greater; I found myself needing to use a 135° tilt to qualify a 3x50mm T in the Z+ direction. The retract after qualification was too far in the Z- direction when it came off the reference sphere. Link to comment Share on other sites More sharing options...
[Ri...] Posted October 14, 2022 Author Share Posted October 14, 2022 Tom Oaks No I did not try the Robust setting. Jon Drown And why didn't I think of articulating the head with an L or T shaped styli.... 🙄 🧑💻 🤣 🫣 Link to comment Share on other sites More sharing options...

[Ro...] Posted October 14, 2022 Share Posted October 14, 2022 And then comes the decision on which way to construct your L or T probe, as you can only hit half of the possible probe approaches with one orientation, either left to right or front to back. You need 2 to cover all the options. Link to comment Share on other sites More sharing options...
[Jo...] Posted October 17, 2022 Share Posted October 17, 2022 Please sign in to view this quote. With the XXT you can rotate about the A axis and hit all of your Z+ options. I have a 1.5x30mm L probe that I use for almost all of my "underneath" probing needs; front, back, left, and right "up" probes. If you are at B=90° with an L configuration you can achieve this by rotating about the A axis although I do have a "right" probe (A=0° B=0°) just so it has a normal down position for the XXT to be in when its picking up and putting away the stylus. It's not pretty, but it totally works. Link to comment Share on other sites More sharing options...
