Calibrate Center Of Rotation - Alpine ALS 4.0 Manual De Instrucciones

Step 10 – Release L1 Clamp using "L1 Clamp Up" button.
Step 11 – Release L1 pusher using "L1 Pusher Out"
button.

Step 12 – Remove the board from the saw.
Step 13 – Check the 90° cut with a framing square,
referencing from back fence side of the board.
Figure 73
Step 14 – If the cut is square, skip to Step 15. If the cut
is not square, determine if the cut is more than or less
than 90° by observing the location of the gap next to
the blade of the framing square. If the gap is on the
inside corner of the square (near the back fence edge
of the board), then the cut is more than 90°. Subtract
the value that the cut is over 90° from 90 and use the
"Move A1" button to correct the angle. If the gap is near
the front of the board, away from the inside corner of
the square, then the cut is less than 90°. Add the value
that the cut is less than 90° to 90 and use the "Move A1"
button to correct the angle. Repeat Steps 1-14, using a
different value for Step 4.

Step 15 – The A1 axis is now ready to calibrate. Touch
the CAL A1 button in the Manual Control Screen.
This will tell the program that the A1 axis is properly
positioned at its calibration point of 90°.

Calibrate Center of Rotation

The width of the Center of Rotation cut must be 15/32"
(11.91mm). This dimension is twice the kerf (width of
the cut made by the saw blade).
Step 1 – Place a 2x4 board (dimensional lumber) across
L1 & L2.
Step 2 – Engage the L1 & L2 Pushers by pressing the
"L1 Pusher In" and "L2 Pusher In" buttons on the Manual
Control Screen.
Step 3 – Engage the L1 & L2 Clamps by pressing the
"L1 Clamp Down" and "L2 Clamp Down" buttons on the
Manual Control Screen.
Step 4 – Move T1 to "1.75" using the "Move T1" button
on the Manual Control Screen.
Step 5 – Confirm Z1 is at "0.0".
Step 6 – If the saw is equipped with a bevel axis,
confirm that B1 is at "0.0".
