Using the GCC AAS II Feature

Applies to version 3.20 and later

Using The GCC AAS II Positioning Feature
The GCC AAS II feature for compliant GCC cutter models is now supported. This allows automatic synchronisation of printed graphics for contour cutting.

Overview of the Process

  1. Create your design and assign the Cut Around property to the paths you want to cut, rather than print.
  2. Set up the print job to include the GCC AAS ”L” markers for synchronisation and print.
  3. Load the printed sheet to the cutter and cut.

Assigning the Cut Around property

  1. Select the path object you want to cut. You can select multiple objects if you wish, and assign the cut around property to all of them together.
  2. Right-click and choose Properties from the local menu, or from the Object menu, choose Properties, or press Ctrl+Alt+P. The Object properties dialog appears.
  3. In the section marked Cutting, tick the check box marked Cut around. If your layout includes overlapping contours and/or subpaths you can force the program to cut only the outermost contour. Just tick the check box marked Outermost only.

Set up the PrintCut job
To prepare your print job for PrintCut you will need to:

  • Set up page margins to prevent printing inside invalid areas of the printed page (the cutter needs some clear space around the page margin)
  • Enable the GCC AAS system
  • Choose the positioning method.

Setting up the Page Margins

  1. In Castop Plus R3, from the File menu choose Print.. The Print dialog appears.



  2. Click the button marked Page margins. The Internal margins dialog appears:



  3. Enter the margin values as they appear in the picture above. These are the minimum values required by the GCC AAS II specification. You may be able to reduce these values to gain printing space but the marker detection process may fail in that case. Click OK to apply.

The picture below shows the media sheet layout as detailed by the GCC AAS II specification.



Enabling the GCC AAS II Positioning system

  1. From the Print dialog, click the tab marked GCC AAS. The GCC AAS tab activates.
  2. Click the checkbox labelled Enable GCC AAS.


Choosing the Positioning Method
There are 3 options to choose according to the requirement of the individual printcut job.


4-Point Positioning
The simplest method for small or medium print sizes. This places 4 markers at each corner of the design. The GCC cutter detects the position of each marker in turn before cutting the assigned cut contours.



Allowable Parameters

  • Margin 0-50mm [The shortest distance between Object and Mark]
  • Thickness 1mm or 2mm [Thickness of Mark]
  • Length 10-50mm [Length of Mark]


Segmental Positioning
Used for larger designs to increase accuracy. Places multiple markers around the design.



Allowable Parameters

  • Margin 0-50mm [The shortest distance between Object and Mark]
  • Thickness 1mm or 2mm [Thickness of Mark]
  • Length 10-50mm [Length of Mark]
  • XStep 200-600mm [Distance between segments in vertical direction]
  • YStep 200-600mm [Distance between segments in horizontal direction]


Multiple Copies
To create multiples of the same design on a larger sheet. Places 4 markers around each copy.



Allowable Parameters

  • Margin 0-50mm [The shortest distance between Object and Mark]
  • Thickness 1mm or 2mm [Thickness of Mark]
  • Length 10-50mm [Length of Mark]
  • No. of X copies Variable [Copies in vertical direction]
  • No. of Y copies Variable [Copies in horizontal direction]

Loading the Printed Sheet

  1. Load the top of the printed sheet to the front of the cutter.
  2. Set the origin point near to the corner of the L marker at the front right side.
  3. Place the cutter On Line.

Cutting

  1. Click the Cut around tab.
  2. Click the Start button.

Calibrating
Castop Plus includes calibration to compensate for any small errors in the alignment. This is controlled using the section named Calibration displacement. Simply measure the displacement of any error and enter the corresponding value to the X (Vertical) and Y (Horizontal) boxes. You can enter a value of -3mm to +3mm.
