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

     I was told by 3D that the "waiting..." message may be due to
     overworking the PC's short term memory. This may be caused by large
     logging files.
     Check C:\WINSLA\PROCYON.MDB file to make sure it is not getting too
     big. Purge your build and event log files. Make sure your SETUP -
     WRITE LASER LOG is not checked on (unless you have some use for it).
     You also may need to fool around with your Virtual memory paging
     numbers found in your system setup.
     One other thing that may free up memory is if you are not running any
     kind of remote display of the buildstation, go into SETUP - CUSTOMIZE
     and turn off the NETWORK BROADCASTING feature. This feature turned on
     constantly polls for network traffic and may use up some memory to do
     Hope this helps.

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
Paul Bernhard
