RE: Problem with Buildstation Software 4.1.1. (SLA-500)

We did have a similar problem and by doing a hard boot at the buildstation once a week or especially before building any complex geometry, it seems to work around the problem. Doing a hard boot will clear up your RAM memory. I don't have a real solution for you, perhaps, 3D can shine some light on this issue.

Subject: Problem with Buildstation Software 4.1.1. (SLA-500)

Dear SLA-500 users,

We have been running Maestro 1.9.1. and Buildstation 4.1.1. on our
SLA500 for a couple of months. While building is fine, we have, for some
parts, made the following observation:
After finishing drawing one layer the machine would wait for a certain
period of time with the message "Waiting for layer end ..." on the
screen before going in the regular predip and recoating phase. This
period may take up to several minutes for certain parts adding
tremendously to the overall build time, since it happens on every layer
! When the build is aborted and restarted the machine builds normally
without this extra delay but it may reappear later again. We have been
unable to trace the problem further but it seems to happen mostly on
large and fairly complex parts.
Has anyone with a similar machine configuration made this observation
and an idea where this is coming from ? And how we (or 3D) can fix the
problem ?

Many thanks in advance for your help
