1-3-2. Replacing the Y-Axis Limit Sensor and the Y-Axis Home Proximity Sensor

∗ If only the sensor is replaced, it is not necessary to adjust the position.
∗ If the sensor is replaced together with the bracket, it is necessary to adjust the position.
1) Loosen the screws fixing the Y-limit sensor bracket and make the adjustment so that the
distances from the split pin mounting center position of the base frame are those shown in
the Figure below. After the adjustment has been completed, tighten the screws firmly. (See
Figure 1-3-2-1 (M and L board specifications) and Figure 1-3-2-2 (XL board specifications).)
