I have been dealing with Siteworks crashing for what seems to be no reason. The nearest I can tell is if you start moving around to fast in it. It will crash and say something like Siteworks is not available or something like that. I had it do this to me in the middle of site cal right after I moved my base to the next set up. When I shot the next control point I had a big vertical error which made me think that the HI was not carried over. Now this presents a two fold issue. I tried to reset my base with the correct HI since it still was holding the temp point name I shot to move my base up to. This is when the crash happened and I lost everything. Now I have to go back and start over again. Maybe I shouldn't have tried to edit my base position or the software won't allow me to. Either way I think there should be an option to edit that setup in the event something like this happens. I use a fixed height tripod for my base so it usually always holds the same height every time I set it up once it has been set up on a job site. I also think that when doing a site cal and using the moving base option Siteworks should save all the base positions you used to complete the calibration. But hey that's just me. Also, I am using the most up to date firmware 1.10 on a TSC7. If someone could tell me where to find the error log/file I would gladly send it along. I have the Auto send diagnostics enabled so maybe it sent it already.
