Calibrating
The following calibrations must be performed after the conversion.
●
Position "calibration of ejection needle"
This calibrates the height of the needle so that it is flush with the upper edge of the black ejec-
tion cap (see 15.3.2.5 "Calibration – die ejector needle" [}385]).
●
Check the needle position in the X and Y directions.
The needle tip must correspond with the camera center point (red cross in Vision view) (see
15.3.2.4 "Calibration – segment offset calibration in X direction" [}379]).
