NOTICE
Clean the mapping plate
Clean the mapping plate using a piece of lint free cloth and alcohol. Dust and fingerprints can distort
images and cause the mapping to fail.
Step 4
Fig.227: Closing the cover
► Close the machine cover. (1)
► Click Ok.
ð The machine locks the cover, the table
raises to clamp the plate, and the cam-
era starts to move to the bottom right
corner of the plate.
Step 5
Fig.228: Setting the light
► Set 2D M-Ring_G light (1) about 10 and
all other lighting values to 0.
► The plate´s bottom right hand cross fidu-
cial comes into view. Click on the cross (2)
to centre the cross to the FOV.

Step 6
Fig.229: “Focus” Icon
► Click on Focus icon (1).
► Set value (2) between 50 ~ 60.
► Click Continue (3) to start the teach table
mapping process.
The progress of the mapping is continu-
ously reported.
NOTICE
At 50% completion, the table towers, the stopper rises, and the plate will move forward to the stopper
to continue the second stage of the mapping. Do not be alarmed by this sudden movement. No user
intervention is required.
Step 7
Fig.230: Message
► A message pops up to report if the teach
process is completed.
Click Ok (1).
Fig.231: Message
► At the next message (2),
click OK to continue with verification (see
section Table Mapping: Verify)
or Cancel to end mapping teach.
NOTICE
If the mapping fails, clean the plate and repeat the procedure. Mapping failures are caused by a fail-
ure to read a fiducial on the plate – usually caused by fingerprint smudges on the fiducials. Verifica-
tion of the mapping results is necessary after a successful Teach.
► Lower the conveyor lift cable.
► Open the machine cover.
► Remove the mapping plate.
► Uninstall the coaxial light.

► Reconnect the Low Ring light connector.
► Open the machine cover.
NOTICE
The mapping information is stored in C:\system\Log\TableMapping_timestamp*.log file (approx.
459KB).
The Delta of Gantry to fiducials` positions should be ≤ 20µm (0.020mm).
4.4.2 Table Mapping: Verify
For verification of positional accuracy of the camera across the work area.
Verify saves time. It takes only 5.5 minutes compared to 63 minutes in Teach.
The procedure is similar to the Teach procedure.
Verify the table mapping again if:
●
The machine is already calibrated but is moved.
●
The positional accuracy of the camera across the work area is suspect.
●
Maintenance is performed on the gantry axes e.g. greasing.
