10 – Motion Compensation
To map both rail axes on a dual gantry cutting table, perform the following steps:
1. Create a “rough” map of the rail axis by entering 508 mm (20 inches) or more for Target Distance on the Laser
Mapping screen, then map this axis, create the data file (see Create the Motion Compensation Data File on
page 228), load the data file (see Load the Data File on page 229), and turn on laser compensation for this axis
(see Turn on Motion Compensation on page 229).
2. Create a “fine” map of the dual gantry axis by entering a normal (much smaller) distance for Target Distance on the
Laser Mapping screen, then map this axis, create and load the data file, and on turn laser compensation for this axis.
3. Turn off laser compensation for the rail axis.
4. Create a “fine” map of the rail axis, using the procedure described in Step 2.
Create the Motion Compensation Data File
The motion compensation data file incorporates the data that the laser interferometer collects. The name of the
compensation data file for each axis must be different so that the CNC can apply motion compensation to the
appropriate axis. Names for the motion data files must use the following conventions:
nameA1U.rtl for the X axis (transverse or rail)
nameA2U.rtl for the Y axis (transverse or rail)
nameA3U.rtl for the dual gantry axis
Note that:
 name can be any valid filename and is not case sensitive.
 The letters A and U must be uppercase.
 The file extension must be rtl.
 The X and Y axes can be transverse or rail. Verify your table’s orientation in the Machine screen.
The contents of the data file must use the following format:
