RE: Smart Feed on 2500+ / Vanguard

Hello Brad

If you haven't used smartfeed yet, I hope you have as good of luck with it
as we have. I use it on practically every build and have grown to depend on
it. The biggest thing to watch out for is very small cross sections in the
part bed. Smartfeed will tend to shortfeed when this is encountered. For
this reason, I normally have smartfeed turned off during warm-up and
cool-down (manually setting the powder feed rate) and turn it on for the
build. You will need to watch the gain control if you are planning on using
the least amount of powder feed per layer (for high builds). Most of our
builds are higher than 17 inches with huge cross sections and smartfeed
works great. Another way you can use this is to watch the smartfeed report
during the build preview (smartfeed turned on) and compare that to your
normal feed rate (that you set manually). You can change this value with the
Smartfeed gain control. Once you use this for a while, you really get used
to it!

Good Luck

Subject: Smart Feed on 2500+ / Vanguard

We have a Sinterstation 2500+ that has been upgraded to a Vanguard machine.
After a minor incident (short feeding) with a build last weekend, I have
decided to turn on "Smart Feed". I've never had the need to use it before
so can anyone tell me if there is anything I need to consider before I try
it? I don't want to create a whole different problem since I am running a
very large build because I could just set the feed amounts myself and all
problems could be avoided - just thought I would try it in case I ever
needed it again.

On a different note, large STL files have been a topic of late on RP-ML. I
received an 85 MB STL file today but the Build Setup software declares it
is not a valid STL file even though Unigraphics will import it just fine
and even the preview thumbnail in Build Setup displays the model. Anyone
have any ideas how I can make this work? We don't have any of the great
STL manipulating software so unless someone would like to volunteer to
attempt to fix it for me, I'm not sure what other options I have other than
sending it back upstream to whoever originally created the file (last
resort since it was done as a favor to someone else). I do know it is a
gigantic model (approx. 400"x 400"x400") and will need to be scaled down to
fit the available build area -- if I can ever get it into Build Setup!.
