Hi, I'm having a problem with Surfacemap. We are using it on a large old CNC machine to probe large pieces of wood to rebuild a 1903 vintage racing yacht (Thalassa). Basically building point clouds which we can then use to cut new wood. Issue is that program stalls randomly, always towards the end of a long (maybe 5000 points, 7 hours) run. We've tried shorter runs, say 800 points, sometimes it works, sometimes not. No warnings or errors recorded, it just stops. When it works the results are good.

I know that it uses Wxwidgets to write to file, but haven't been able to delve further into this. so questions;
1  Is there a limit on the buffer size?
2  Where is the data stored before it gets written to the .dat file at the end? - I've dome dumps of RAM etc. at the end of the long runs when it has failed and could maybe recover data?
3  Any other ideas why it might be failing?
Thanks, Nick
