Data Management: Supports various data types and integrates with automated design control for craftsmanship and signal transfer. Technical Features & Workflow
File Compatibility: The software can import and process popular file formats including DXF, AI, PLT, and JPG.
Hardware Control: It is compatible with most laser hardware, especially machines using RDXXXX-YM controllers.
License Security: Full operation typically requires a physical USB hardware license key (dongle), which acts as a safety feature to ensure only authorized operators use the machinery. Operational Flow:
Prepare: Design or process images in external software like AutoCAD (saving as 2010 DXF) or Photoshop. Import: Load the file into SmartCarve.
Configure: Set laser power, processing speed, and priority (order of operations).
Connect: Establish a link via Ethernet (preferred) or USB to the laser cutter. Installation and Setup
OS Requirements: Primarily designed for Windows, though it can run on Mac using Parallels.
Network Setup: Users must often configure a static IP address for the machine and ensure the computer is on the same subnet to communicate over Ethernet.
Initial Configuration: Upon first run, users select the language (English) and system version (usually "normal system"). If the machine lacks optical recognition, the "large vision" option should remain unchecked.
💡 Tip: When prepping images for high-res etching, experts recommend using Photoshop to lighten black levels slightly (using Curves) to compensate for the laser's dot size, which can otherwise overpower dark areas.
