Workpiece Preparation
Before carving can begin a number of menu prompts and machine
operations must be navigated.
The machine will ask if the workpiece is to Stay Under Rollers. Keeping
the workpiece under the top rollers is a way of avoiding undesirable snipe
in the cut and maintaining contact with the Board Tracking Sensor at all
times. It is recommended that this option is used when under the
following circumstances:
• Best carving quality is desired
• The project has routing to or near the ends of the board.
• The project has cutting to or near the ends of the board.
• The project is longer than 20 inches and there is carving to the
ends of the board.
If YES to Stay Under Rollers is selected the machine will automatically
assure that there is 3-1/2" extra length on either side of the project. In
many cases you will have to account for this extra length by inserting a
longer workpiece then is shown in the design software. The other option
is to have the project scaled to the board size while accounting for the
length needed to keep under rollers. Most times this will not produce the
desired effect.

The machine will then measure the workpiece. If the size of the inserted
workpiece does not match the size of the designed project then the
machine will prompt for additional information. The machine will ask
different questions based on if the workpiece installed in the machine is
larger or smaller than the project designed in the software. If the
workpiece is smaller than the designed project, then the options are:
Scale the project to fit the workpiece or Load New Board. If the Scale
option is selected then options Center On Board, Jog To Position, or Place
On Comer are displayed in order to locate the project on the workpiece.
WARNING: Be very careful when scaling down a project at the
machine. The machine will scale the entire project to the
largest size that will fit the inserted workpiece while
maintaining the overall aspect ratio of height to width. It will
not change the aspect ratio to fit that of the inserted
workpiece. Scaling down can also lead to undesirable
thinning of carved elements that may lead to chip out.
