Verify Limit Switch Function
Limit switches prevent the mill from exceeding its travel limits and provide a reference location during the mill homing procedure.
There are three limit switches, one for each axis of motion (X, Y, and Z), as shown in Figure 3.18.

If a limit switch is triggered, the mill is placed in a reset state.
To verify proper limit switch function:
-
On the PathPilot interface, click the Status tab. (see Figure 3.19)

-
Manually depress X, Y, and Z limit switches by hand. (see Figure 3.18)
-
Verify that the corresponding limit switch LED light illuminates on the Status screen. (see Figure 3.20)

-
After verifying limit switch function, click the flashing Reset button. (see Figure 3.20)
Verify Axis Function
-
Reference the mill by clicking the Ref Z, Ref X, and Ref Y buttons; (see Figure 3.20) the mill moves.
-
Next, switch to the Main screen.
-
Use keyboard to verify axis motion:
-
To move X-axis, use the ←/→ keys.
-
To move Y-axis, use the ↑/↓ keys.
-
To move Z-axis, use the Page Up/Page Down keys.

-
To test the optional jog shuttle:
-
Press the corresponding axis button (X, Y, or Z) to select the axis.
