Importing SCH & PCB in JLCEDA

1. Open the Project File

MindPaw_SCH&PCB.epro2 is the project file for LCEDA (JLCEDA) Professional Edition by JLCPCB.

Steps to Import:

1. Visit LCEDA Professional Edition (opens in a new tab) and log in
2. Click File → Open → LCEDA Professional Edition in the top menu
3. Select SCH&PCB/MindPaw_SCH&PCB.epro2
4. Wait for the loading to complete; the project panel on the left will display:
   • MindPaw_SCH&PCB.sch — Schematic
   • MindPaw_SCH&PCB.pcb — PCB Layout
   • MindPaw_SCH&PCB.epro2 — Project File

2. Viewing the Schematic

After opening the .sch file, you can see the complete circuit of MindPaw:

3. Editing and Exporting Gerber Files

Modifying the PCB:

• Drag components and reroute traces directly in the PCB editor
• Press Ctrl+S to save after making changes

Exporting Gerber files (for PCB fabrication):

1. Click File → Fabrication → Gerber Files at the top
2. Keep the default settings in the pop-up dialog
3. Click Export; the system will generate a ZIP archive
4. This ZIP file is the standard Gerber package to send to the PCB manufacturer

Importing 3D Models into JLCPCB

Preview 3D in JLCPCB EDA

JLCPCB EDA Professional Edition supports automatic 3D preview generation from PCB:

1. Open the .pcb file
2. Click View → 3D Preview at the top (or press Shift+3)
3. Rotate and zoom to view the 3D PCB model

Uploading 3D Models to JLCPCB

There are 3 STL files in the 3Dmodel/ directory, which are the structural shells of the robot dog:

If you want to 3D print these parts with JLCPCB:

1. Visit JLCPCB 3D Printing (opens in a new tab)
2. Click Upload File → Select an .stl file
3. Set printing parameters:
   • Material: Recommended PLA (best cost-performance) or PETG (slightly stronger)
   • Layer Height: 0.2mm (standard), 0.1mm (fine)
   • Infill: 20% (balance of strength and weight)
   • Support: Enable as needed
