Precautions regarding sacrificial boards
The sacrificial board will become porous when the melamine has been cut through, and will
absorb moisture. As moisture is absorbed the dimensions of the board will change. In general,
this will not be a problem as the changes from day to day are typically very small. Also, the
changes will in general be over the complete board.
There are however exceptions. Do not allow the board to become wet. If the board does
become wet, remove the board from the machine and replace with a new board. Allowing the
board to dry may take several days. Once the board has completely dried it may be possible to
plane the board and re-use it, but the likely hood is that it is scrap.
Attaching Workpiece to Sacrificial Board
Double-sided tape can be used to attach the workpiece to the sacrificial board. If you are using
double-sided tape, ensure that the sacrificial board and the workpiece are clean and do not
have saw dust or chips as this will affect the ability of double-sided tape to hold the job securely.
Only use the smallest amount of double sided tape as it will make it easier to remove the piece
once it has been machined.
Removing Workpiece from Sacrificial Board
Lift the part off the sacrificial board with a wide blade putty knife or similar tool.
Moving the router head to the sacrificial board corner position.
1. With the router head in the home position, lower the router bit to just above the sacrificial
board top face.
2. Use the
,
,
, and/or
keys to set
the X and Y position to the corner dimension.
3. The point of the router bit is now located over the
point that the corner of the sacrificial board should
be.
4. You may need to move the router bit lower so that it
is closer to the top surface of the sacrificial board by
pressing the Z- button.
5. Press the
key. This will set the origin and the machine has a new datum point and will
be the X=0 / Y=0 in your design program.
6. Move the sacrificial board so that the corner of the sacrificial board is directly under the point
of the router bit.
7. Place tape around the corner of the sacrificial board on the bed of the machine. This will give
you a position to place the double-sided tape that will be used to attach the sacrificial board
the bed of the machine.
