[Ri...] Posted October 18, 2019 Share Posted October 18, 2019 The Vast XXT attempted to rotate with insufficient clearance to the surface plate. E-Stop was hit in time and feed rate was reduced to zero, but this did not stop machine movement in A&B axis. When the Z axis of the machine was released the A-B axis continued to move despite being in a emergency stop state.The E-stop failed to prevent ongoing and continued A-B rotation. The Vast XXT continued on until it came to rest in a state of interference with itself where it then continued to attempt to torque through itself. At this point the mains were cut to prevent further damage. Zeiss IMT is unavailable to offer support and I can't leave this thing like this for the next 10 days. Anyone got any ideas or suggestions on how to stop this thing? I can't find so much as a manual for this thing online, let alone a what to do if.

[Ri...] Posted October 18, 2019 Author Share Posted October 18, 2019 I had to cut the power, it was still cranking. Link to comment Share on other sites More sharing options...
[Me...] Posted October 24, 2019 Share Posted October 24, 2019 I'd be interested to hear an update on this, Richard. Sounds like a real headache. It also sounds like the emergency stop is not what it claims to be. Link to comment Share on other sites More sharing options...
[Ri...] Posted November 7, 2019 Author Share Posted November 7, 2019 "Jeff Frodermann" I'd be interested to hear an update on this, Richard. Sounds like a real headache. It also sounds like the emergency stop is not what it claims to be. Please sign in to view this quote. I never got a call back that day. 😡 The E-Stop indeed has ZERO influence over the A-B axis. This of course flies in the face of everything I have found on the design, function and application of emergency stops in industrial and semiconductor equipment. This machine operates in direct contradiction to a whole series of unified machine safety standards that govern the function of a designated E-Stop button. Here is what ISO 13850 has to say about this condition: Please sign in to view this quote. Heres what OSHA 29 CFR 1910.179 (a)(59) says: Please sign in to view this quote. Then there's SEMI S2-0818E , ISO-13850, OSHA 29 CFR 1910, and the list goes on! They used an IEC 60417 symbol to designate the E-Stop button as such, but it does not function as one! Clearly there is an extremely serious safety issue here that needs to be addressed. Physically cutting the power to the machine as I saw causes the Vast XXT head to wretch forward in both axis present direction of travel, further injuring any potential victim and inflicting even greater damage to the machine. I don’t know how things work over in Germany, but when you sell a piece of industrial equipment here stateside it sure as hell better comply with industrial safety standards.

I was about to yell "of course things are handled the same over here!", but thinking about how the authorities go about VW's "Dieselgate" here in Germany, I'm no longer sure.... 😮 Link to comment Share on other sites More sharing options...
[Ri...] Posted December 5, 2019 Share Posted December 5, 2019 Works in Simulation.... In all seriousness, I'm not certain why it would even attempt to allow you to do that. I'm also not certain as to why the E-Stop didn't work. Did you ever contact Zeiss, and get this resolved? Link to comment Share on other sites More sharing options...
[To...] Posted April 8, 2021 Share Posted April 8, 2021 Please sign in to view this quote. Calypso now limits the B axis rotation to ±160°. In the RC List,you can enter a value greater than ±160° and it will try to go there and trigger a limit, but it won't crash. I think they should not allow a value greater than ±160°. For example, now, if you enter 190°, it will change it to 180°. Just have the software automatically change the value to 160° if you put in a larger number.
