Table Calibration
Feed a test board through the sander and measure it in
many locations on both sides along the length to test the
accuracy of the digital thickness gauge.
To calibrate the digital thickness scale, do these steps:
1. Using a properly set-up planer, plane a board to
uniform thickness.
2. Adjust the sander table far enough to place the
planed board under the sander roller.
3. Using the handwheel, manually raise the table until
the board just touches the sandpaper.
4. Remove the board without changing the table
height. This ensures the table will be properly
adjusted for the first sanding pass.
5. Run the board through the sander several times at
the initial height setting. Manually raise the table
0.020" and pass the board through the sander several
more times. Monitor the amperage meter and the
resulting load on the sander.
6. Measure the thickness at various points around the
board using a precise micrometer or set of calipers.
7. Continue sanding the board at that height until the
average thickness measurement is within + ⁄
-
0.003".
Note: These final passes should be done without
adjusting the table height. This ensures the most
consistent average thickness.
