Preparing a Layout

• Insert a USB thumb drive containing your DXF File into the computer.

• Double Click on your DXF file to open the import menu for OMAX LAYOUT

• Compare the size of your part to the preview size listed on the top

  • If these values don't match, re-export your dxf from CAD in inches

• Click [OK] to continue

To ensure a valid toolpath the imported DXF must be "cleaned" to check for gaps, or overlapping lines.

• Click [Clean]-->Click [Start]

• Review the report, if anything was changed, your should repeat the cleaning again until 0 entities are changed (if the file is still changing after several cleanings ask staff for help)

The cut order of the part is important; interior cuts must be performed before the exterior, or the accuracy is reduced. If the software does not automatically do this, there is some issue with your source file.

• Click [AutoPath]

• Review the generated path to verify the inner shapes are cut before the perimeter

• By default the path will place a start position in the bottom left corner, and the exit point in the top right corner.

• The path shown in this example:

  • Starts in the bottom left

  • Travels along the green line to the right hole

  • Cuts the right hole

  • Travels to the left hole

  • Cuts the left hole

  • Travels to the perimeter of the part

  • Cuts the perimeter of the part

  • Exits to the top left (non-standard)

If you part is smaller than 3 inches in any direction, it is possible it can fall through the cutting table after it is cut and be lost in the tank, or break the cutting nozzle. To prevent this a small portion of the perimeter can be left uncut so the part stays attached to the sheet.

• Hold [ctrl+T] to access the tab tool or [Right Click on Lead I/O]

• Hover your mouse near the area of the tab to see a preview and [Left Click] to create the tab

The cutting jet of water has a known diameter. To create accurate parts the jet is offset by the radius, to leave the correct amount of material for your part. You must verify that it is offset the correct direction.  

• [Left Click on Post]

• Move your cursor to the start of the first green traverse line (default is bottom left) and [Left Click]

• Verify the cutting paths in the preview (hold left/right click to zoom in/out)

• Click [Save]
