Configure Machine Zero Offset and Verify Reference Mark Startup Position
•
Configure and verify the correct encoder resolution and count direction for all axes.
•
Set the Reference Mark type correctly for each encoder being configured.
•
At the Main Mx200 Settings screen press the “Set Home Position” button located at softkey 1.

•
Cross the reference marks for each enabled axis, as prompted.
•
Position the stage at the desired startup zero position in each axis being configured. Place some
artifact within the measuring view and align it with the center crosshair position.
•
Enter Setup, Axis Setup, Choose X Axis, and then select the Menu item called “Machine zero
offset”
•
Press the “Use Current Position” button to set the offset(in counts) from the detected startup
encoder position to the current stage position.
•
Repeat the previous (2) steps for each axis configured for reference marks.
•
Restart the Mx200 and cross reference marks at startup. Position the crosshair at you
comparison artifact location and verify that the stage position reports zero in the readout for
each enabled axis.
•
Drive to a new stage location and repeat the step above, again verifying machine zero at
startup.

Optical Edge Sensor Setup and Calibration
Note:
Systems not equipped with an Optical Edge Sensor support can skip this section and proceed to
section 2.8. Systems equipped with Optical Edge support must have the Factory Option enabled prior to
proceeding. Verify using the following setup screen sequence;
Mx Button-->Setup-->Enter Password-->Factory Options-->Verify the Optical Edge item is set to “Yes”
Verify that the Screen and Reference Fiber Optic cables are mounted on the measuring machine
according to the manufacturer specification and connected to the correct fiber optic inputs on the
Mx200 readout. See section 1.3 D for more information. Perform the reference fiber adjustment and
optical edge sensor calibration steps below.
