RE: 3D Lightyear and Buildstation on SLA 500s

Carl, As one of the many beta sites on this software -
we are still running mostly default settings and can honestly say that this S/W
has some great potential - BUT!


We early on ( after purchasing a new 5000 - thus the new beta test facility ) took in a job that required four identical parts to be built.
We ran default all the way even auto placement, nothing complex as far as the part or the build parameters - verified, sliced everything looked great but it failed.
Part is roughly 18" X 18" duct type part with wall thickness of 0.300" .
So far we have run the build 10 times for four parts - even after we had a successful build file ( we thought ) we would run the same one again and the next build from the same Bff file would not build - we have really had to open up the magic book on this simple part - the sad part is the 160 hours that this part
takes to build , you really hope that it dies at 0.800" rather than at 16 or 17 inches. A fix your looking for is it? I wish I could help! Phantoms of the SLA's.
And yes we tried quite a few different fixes - just about the time you think it is a done deal you try to replicate the same build that built perfect and BONK.
The phone lines will be busy.
Karl feel free to call if you like.

P.S. It is Painfully obvious that little if any enhancements to support the SLA 250's or smaller platforms was an issue, 3-D Systems needs to recognize that these platforms are not going to go away!
