Before starting with any Marking On The Fly application, the optic system needs to be well-calibrated in the static situation (no belt movement). A precisely calibrated static system (correction file and optic settings) is absolutely required and really critical for a good marking results in the dynamic system.

 

It is recommended to start with neutral optic settings:

SAMLight → Settings →  System → Optic:

▪Disable X invert, disable Y invert and disable XY flip.

▪Set X gain to 1.0, Y gain to 1.0 and rotation to 0.0°.

SAMLight → Settings → System → Optic → Advanced → Correction, Settings:

▪Set X gain to 1.0, Y gain to 1.0 and rotation to 0.0°.

▪If necessary, inversion, flip of axes and rotation can be included in the correction file *.ucf using <SCAPS>\tools\sc_corr_table.

Start (without any movement of your target) to check the calibration in the static situation:

•Make sure your encoder does not send any pulses.

•Mark a job like ABC-circle.sjf: Is the orientation (X and Y axes) of the marking result correct - is the text "ABC" readable?

oIf not, the correction file must be manipulated. This can be done using <SCAPS>\tools\sc_corr_table (correct the orientation).

•Mark a job like Grid.sjf: Are the X and Y aspect ratios correct? In other words: is 1 mm in the drawing very precisely 1 mm on the target in vertical and horizontal direction throughout the whole working area (not only in the middle of the field)? This is very important for 1D Mark On The Fly split applications, because the start point and the end point have a quite big distance within the scanner field in such an application. This is even more critical with increasing speed of the line and with increasing size of the closed shapes.

oIf not, adapt the field size until the dimension in the direction which you want to use as MOTF axis is correct. Mark again: are the X and Y aspect ratios correct?

▪If not, adapt the gain value of the axis, which is not used as MOTF axis. Mark again: are the X and Y aspect ratios correct?

•If not, improve the correction file with sc_corr_table. Please find further information on how to work with sc_corr_table online.
