[Da...] Posted April 9, 2018 Share Posted April 9, 2018 I have noticed when using the “stylus system creator” and “simulation” on machine with a RDS probe head and VAST XXT sensor, the stylus is not contact with the feature I am trying to measure. Do anyone know why this is happening? Attached is a screenshot of the values I entered for the “Stylus System” tab in the CMM configuration on my offline seat. I received these values from Zeiss many years ago.Simulation with RDS and VAST XXT.PNG Link to comment Share on other sites More sharing options...

[Lo...] Posted April 9, 2018 Share Posted April 9, 2018 Dave, Our offline is Xs=0.0 / Ys= 55.0 / Zs=135.00 Link to comment Share on other sites More sharing options...

[Lo...] Posted April 9, 2018 Share Posted April 9, 2018 Please sign in to view this quote. Nope.. Vast XXT. I had the same issue with simulation not contacting the model. Zeiss Tech support adjusted these. On our off line seat there are 2 tabs on the bottom of the Extras>Settings>CMM>Stylus system The contura tab has Xs=0.0 Ys=60.0 Zs=192.900 On the simulation tab I have: Xs= 0.0 Ys= 55.0 Zs= 135.00 Vast XXT RDS Link to comment Share on other sites More sharing options...
[De...] Posted April 9, 2018 Share Posted April 9, 2018 On the contura tab mine is Xs 0.000000 Ys 60.000000 Zs 191.700000 While the simulation tab Xs 0.000000 Ys 0.000000 Zs 0.000000 I had to get these numbers from Zeiss as well. I just had this problem. Then we had to import the probe after reconnecting to the simulation tab. Link to comment Share on other sites More sharing options...
[Da...] Posted April 9, 2018 Author Share Posted April 9, 2018 All, I am using Calypso 2017 (Version 6.4.04). Does the software version make a difference for Xs, Ys, and Zs values? Link to comment Share on other sites More sharing options...

[To...] Posted April 9, 2018 Share Posted April 9, 2018 Hey Lonnie, Can you post a screenshot of your RDS/VAST-XXT and MasterProbe in Stylus System Simulation using the configuration that uses the 0,55,135 values. Link to comment Share on other sites More sharing options...

[Da...] Posted April 10, 2018 Author Share Posted April 10, 2018 Thanks everyone! Thanks to Matt, found the Zs value of 191.7mm was the trick! Link to comment Share on other sites More sharing options...

[Lo...] Posted April 11, 2018 Share Posted April 11, 2018 Please sign in to view this quote. Here is the adaptor plate.. I think I see where you're going.. The adaptor plate is significantly lower than it should be, but the stylus contacts the parts during simulation.Master probe3.jpg Link to comment Share on other sites More sharing options...
[To...] Posted April 13, 2018 Share Posted April 13, 2018 Lonnie, I was interested in the RDS Adapter, where the XXT screws in at the top. Link to comment Share on other sites More sharing options...
[Ri...] Posted April 13, 2018 Share Posted April 13, 2018 The 0,55.00,135.00, xs,-ys,-zs settings are from the old RST days. A trigger head Zeiss sells for the RDS head. 0,65,192.00, xs, -ys,-zs values are more typical of XXT. I have found different versions and different SP's, especially those involving major changes to the Stylus System Creator can require "tweaks" to the initial Stylus System fields but more then likely it's "tweaks" to the qualification data for the individual styli position of a single styli. I have used "Plan/Travel to nominal position" for that. There are a couple things you may want to do first, like set your styli radius to zero. When you travel to your nominal point, the styli should be at ball center. Link to comment Share on other sites More sharing options...
