Setting up the Rotary

Images imported to EzCad must be a .DWG file, as Bitmap files are not supported when using the rotary.

1. Connect the rotary tool’s 4-pin connector to the port in the workspace located on the front of the machine.
2. Fix the object to the chuck rotary, ensuring that the part is flush.

3. Adjust the angle of the chuck rotary so that the part is perpendicular to the lens of the fiber laser.
4. Turn on the Light (F1) to ensure that the part is aligned in the desired position. The red dot guide should be centered on the object.
5. Use the focal stick and the Up/Down switch on the left-side of the machine to calibrate the lasers focus.

Marking Text w/ Rotary:

1. In EzCad, click “Laser” --> RotaryTextMark
2. Define the diameter of the object, this is important to ensure that objects are marked with proper spacing and shape.
3. Axis Step defines how far the rotary will rotate when Ctrl + Left/Right Arrow Key is pressed. This does not affect any actual marking, it is simply a tool for manually rotating and does not affect the origin (when marking is started, laser will return to the initial home position on the part).
4. By default, the axis is set to Y and is inverted. If you wish to mount the rotary on the right-side of the workspace, then switch the axis to non-inverted by unchecking the “Invert” box.
5. Turn on the Light (F1) to ensure that the text is in the proper position (RotaryTextMark will frame the position of the first character in the text).
6. Begin marking by clicking Mark (F2).

Marking Image w/ Rotary:

Images marked with the rotary tool must be in .DXF format.

1. In EzCad, click “Laser” --> RotaryMark

Marking By Split Size

1. 1. The “Expansion Axis” is preset to Y by default and should be inverted when rotary is placed on the left-side of the machine. If you wish to mount the rotary on the right-side, then switch the axis to non-inverted.
   2. Define the marking split size, this will determine the size of the marking region before the rotary moves. When engraving smaller objects, it is best to use a split size that is small to ensure the laser does not become out of focus on the curvature of the object.
   3. A split size of 0.05 or 0.10 works well for most objects as the interval is small enough to negate the distortion caused by the curvature.
   4. Note: Marking speed may be increased by increasing the split size, but too large of a split size can result in loss of focus.
   5. Ensure that “Force all split” and “Mark by split line” are not selected.
   6. Define the objects diameter by clicking on “Part Diameter” in the RotaryMark window/
   7. Turn on the Light (F1) to see the framing of the first split size, if split size is small the framing will appear as a line, rather than a box.
   8. Begin marking by pressing Mark (F2)

Marking By Split Line

1. 1. The “Expansion Axis” is preset to Y by default and should be inverted when rotary is placed on the left-side of the machine. If you wish to mount the rotary on the right-side, then switch the axis to non-inverted.
   2. In the RotaryMark window, double click on the preview in locations you wish the rotary to split the engraving. A red dashed line will appear. The rotary will rotate each time a split line is reached.
      
      Note:  To remove a split line, right click it in the RotaryMark preview.
   3. Ensure that “Mark by split line” and “Force all split” is selected.
   4. Define the objects diameter by clicking on “Part Diameter” in the RotaryMark window.
   5. Turn on the Light (F1) to see the framing of the first split location.
   6. Begin marking by pressing Mark (F2)
      
      Note: Focus Length parameter does not need to be adjusted.
