XM multi-axis calibrator
Data capture
Roll tuning
When Start is selected the system will perform a calibration cycle on the roll
detection scheme to compensate for the set-up conditions.
Sign detection
To ensure the errors of the machine are measured with the correct sign (+/-) it
is important that the coordinate system of the XM (X,Y,Z and their directions) is
labelled according to that of the machine. Further details on sign detection can be
found here.
There are two methods of sign detection:
• Automatic
Part programs produced with CARTO will perform machine moves to detect
the sign.
• Manual
The user can manually jog the machine ±150 µm in each axis when
prompted by the software to perform sign detection.
Note: Users can skip an axis if they don't have three perpendicular
axes. Further details can be found in the Capture user guide.
On completion of these steps the system will start capturing data.
