[No...] Posted April 10, 2018 Share Posted April 10, 2018 Can anyone tell me what's the technical difference between the VAST XT and XT gold head? I mean besides the golden letters and the golden price tag. 😉 Link to comment Share on other sites More sharing options...
[Ri...] Posted April 30, 2018 Share Posted April 30, 2018 The "Gold" version was designed and intended for Navigator systems that can run scarey fast. Running at Navigator speeds means collisions are typically spectacular and extraordinarily costly. The VAST Gold and VAST XT Gold are built so they maintain good durability running at those speeds day in and day out and can withstand a knock or two.

[No...] Posted May 2, 2018 Author Share Posted May 2, 2018 Then we must be extraordinarily unlucky 🤣 The last 17 years of owning our Contura were a sad story of many (>10) VAST XT head replacements, some only lasting 6 months, two having a twisted probe holder, etc. Some weeks ago, when the last head went bad after 5 years (yay!), we got an XT gold for the first time. It needed only two weeks to break down 😮 At least it can carry longer (500 mm instead of 300 mm) and heavier probes. Now if that isn't something!

[To...] Posted May 2, 2018 Share Posted May 2, 2018 It's really important to balance your stylus systems, or what Zeiss calls "Tilt Torque". I've attached a segment from their Styli Handbook. An unbalanced stylus system is constantly using the tare motors ( I know I'm probably not using the correct terminology) to keep it balanced causing premature failures.

[No...] Posted May 2, 2018 Author Share Posted May 2, 2018 Most of our probes are balanced. Some of them can't be because there's not enough space. My personal opinion is that some refurbished heads are of questionable quality. When two heads in succession have twisted probe holders right out of the box, something is wrong 😡 Link to comment Share on other sites More sharing options...

[Da...] Posted May 4, 2018 Share Posted May 4, 2018 Please sign in to view this quote. Tom, do you have any specs on the XTR head ? I always try to balance best I can. How do you find the L1 length ? Link to comment Share on other sites More sharing options...
[To...] Posted May 4, 2018 Share Posted May 4, 2018 Unfortunately, I do not have any info on the XTR. Even though I understand the math but I don't know how to calculate the L1 value. Hold it up between 2 finger until it appears balanced???? 😉 Link to comment Share on other sites More sharing options...
[Da...] Posted May 4, 2018 Share Posted May 4, 2018 Please sign in to view this quote. That's pretty much what I came up with 🤣 🤣 But , the XTR spec. would be interesting. I hear people say they run with L shaped set ups. I always run with T setups to maintain balance. Link to comment Share on other sites More sharing options...
