System Check
Check Movement
Open the keypad control using the yellow keypad button on the red posi-
tion window (or press the “K” key). Test for tool movement using the arrow
keys to move X and Y. Move the Z-axis up and down using the Page Up
and Page Down keys.
Check Stops and Targets
Check that the physical stops on the tool are tight and will not move when pinions hit them.
Make sure proximity target bolts are secure in the locations stated in earlier section. Check that the
proximity sensors have 1-2 mm clearance over target bolts.
Note: If the stops and targets are not properly installed, a tool crash will occur in the next step.
Check Limit Switches
The proximity switches have red LED lights that are lit when the switch is not over a target. Look at
each switch to identify this light. Place a small metal object such as a flat blade screwdriver near the
end of the sensor. The LED light should turn off, and then turn back on when the object is pulled away.
Test the function of the limit switch and target setup. When set up properly, the sensors should “see”
the targets and cause the tool to stop approximately 1/4” before the pinions hit the physical stop
blocks.
Open the keypad and hold down the left arrow key to move the gantry in the negative X direction. The
gantry should move down the rails until it encounters the limit switch target where the gantry should
stop abruptly. Once the tool stops, release arrow key.
Note:
Do not attempt to “sneak up” on the target by repeatedly pressing the arrow key. This can cause
the tool to go past the target and not function properly. Always hold down the arrow button until the
tool comes to a stop
Zero the X-axis:
Click on the Zero Axis button on the keypad. Select the X checkbox and click the
ZERO button. Notice that the X value changes to 0.000 in the position window.
Move the X-axis off the proximity target using the right arrow key.
Note: If the axis is not moved off the proximity target, the other proximity switches will be disabled
and the next step will not perform properly.
