You need the DXF import feature enabled in the Universal Laser software.

You can turn on 'onlyCutting' to only include the actual cutting passes the output. By default the property 'excludeRetracts' is enabled and will leave out retracts from the output. You can enable the property 'writeCuttingModes' property to output the cutting mode color assignments.";
