Nesting; Non-Optimize Look Ahead - Alpine ALS 4.0 Manual De Instrucciones

• Combine all Grades – When this option is
checked, the computer will choose from all
pieces of the same size without regard to a grade
requirement. Make sure that the highest grade
required for the job is available.
CAUTION
!
This will improve the waste factor, but should be used carefully to
make sure that lower grade lumber is not used on pieces requiring
higher grades.
• Longest Pc Left – By selecting this option, the
Optimizer will look through the job for the longest
uncut piece that will fit on the stock each time it
places a piece for cutting. This is helpful when TRS
files are not sorted long to short and it is desired
that the longer pieces to be cut first for stacking.
NOTE
Longest Pc Left will work when the optimizer is on or off, but its
usefulness will be limited by the Non-Optimize Look Ahead
setting (refer to Figure 44). Alpine recommends setting this value
greater than 2 when using Longest Pc Left without the optimizer
on. See section 3.8.5 for more information on the Non-Optimize
Look Ahead.
• Cut All Within Size – Allows cuts to be organized
by width of lumber. All 2x4 pieces will be cut
before the saw asks for a 2x6, 2x8, etc.
• Crown Up – This option will tell the saw software
that top and bottom chords should not be flipped
for nesting. It may be useful to select this option
so all board labeling will be facing up during
assembly on the tables.
• Truss by Truss Cutting – Turning this option on
will prompt a screen listing the individual trusses
within the job. Select the specific truss or trusses
required and when cutting begins, the saw will cut
all of the pieces from the selected truss regardless
of where they are located in the TRS file. This
option can be used to simplify the lumber sorting
process. Each truss will be cut one at a time and
can be sorted and stacked accordingly.
3.8.4

Nesting

Found in Figure 31 of Section 3.5.3, these options turn
on the nesting function for the type of joint interfaces
shown. If nesting is turned off, the computer will leave a
small gap between the pieces.

Non-Optimize Look Ahead

Non-Optimize Look Ahead creates a moving window
within which the Optimizer is fully functional in the Run
All – Optimize Off mode.
Enter a value greater than 1 to limit how far ahead the
program will search for optimizarion. As pieces are
completed, new pieces take their place in the Look
Ahead.
The Optimizer is fully functional, but only within a
relatively small section of the TRS file. This means
that some optimizing benefit will be available, while
restricting the size of the job for easier sorting on the
output side of the saw.
Non-Optimize Look Ahead is best used when cutting truss-by-
truss, or straight down a cutting list generated by truss design
