Listed below are some common questions and answers about the Video Jet Printer Head.
Q: Can the system be setup to reduce the potential for a crash? As an example, I customized our current NC Post Processor so that it would not generate code if a router tool cut depth exceeded the panel depth by more than 1/16”.
A: Yes, the head distance away from the top surface of the part controls the text spray size(height). This can be set in the knowledge of the cut. Caution must be exercised as you get closer the surface of the material on order to prevent crashes.
Q: How is the information supplied to the 4-label fields?
A: CSV,Excel import, or data entry directly into the parts screen are the possible methods to populate a part record with label data
Q: Can the text be printed smaller than the .1875 - .375wide characters as noted? At this size a string of 20 characters would be 5”wide.
A: Yes, the head distance away from the top surface of the part controls the text spray size(height).
Caution must be exercised as you get closer the surface of the material in order to prevent crashes.
Q: Is inserting text on layer LABELS the only way to drive the Video Jet Head?
A: That is only 1 of the 2 methods possible. Imported data as discussed above might be the better way to insert label data.
Q: Where does the information come from for the inkjet label (part drawing, etc.)
A: Each part record has up to 4 label fields that are available to be printed on the center of the part but the user must consider the text size and text length in there printing. Each char in a printed message is approx .25-.375 in length. In addition the user may place text on a layer called LABELS and this will also be printed on the part.
Q: What dictates the orientation of the label (0 or 90 degrees)
A: All text will be printed with the rotation that nesting assigns to the part automatically.
Q: Speed of the inkjet labeler/printer
A: 450 IPM is the best speed to print so far.
Q: I only get a few characters printed and then a blob of ink at the end.
A: This seems to be caused by either changing the feedrate so that it is too fast for the videojet to print the characters in the length of the move allowed, or by changing the text parameters in the NC file after the code has been produced.
