Remember that to change a build style layer thickness, you need to
change the recoat thickness simultaneously.

Steve, Andrew,


I have Lightyear 1.3 & 1.4 and have never been able to get either
package to accept a build parameter change mid-part even on a single
part platform.

The error is always incompatible layer thickness.

Recoat I can change OK.

        Yes Steve

        It can be done, but it depends which version of Lightyear you
are running. I believe it couldn't be done in older versions.

        You will probably have to utilize the "General" styles (with
their wider parameter allowances) to achieve what you want and beware
the dreaded Blade Gap parameters in the Recoat Parameters as they are
related to the Layer Thickness. You will have to change those also.
It is advisable to stick to multiples (e.g. 0.004" and 0.008" or
0.003" and 0.006" etc.) It's still sometimes tricky though and care
should be taken...don't experiment on a vital build!!

        What your guys probably mean is that you can't apply 0.004" to
one part and 0.005" to a different part. Remember, all parts on one
given layer must have the same Layer Thickness - so if you change LT at
2 inches into one part, you should change at the same point on ALL the
parts on the platform.

        Good luck - let us know how you get on

                Hi, all -


                I started running our first 250 in 1990, so I believe I
qualify as a dinosaur. I have not had to actually run the machines
myself for several years (since Maestro).


                In the olden days, we used to use different ranges of
layer thicknesses within a part. I'm 99% sure that we could run one
build style in a given range in Maestro, then change to a different
build style as we proceeded up the part. So, if I wanted to build .006"
layers on a real straight section, then .003" layers on an area I wanted
finer detail on, I could do that (historical note - we used to use .010"
layers and said that was "plenty good," then went down to .005" if we
REALLY wanted detail).


                My LightYear-trained guys say this cannot be done. They
say only one build-style is allowed per platform (they agree you can do
different recoat styles, but not build styles).


                I'd appreciate your feedback - is this really true?
Obviously, I don't have 3D maintenance, or I'd be calling them to ask
