Learning Objectives

• Export .svg TRACE & OUTLINE files
• Converting .svg (image) files to .rml (milling) file...using MODS
• Use the Roland SRM20 to mill a PCB with .rml files
• “Stuff” the milled PCB with surface mounted electronic components
• Programming the board

Eagle: Exporting SVG File

Two .svg (image) files need to be exported from Eagle to mill a PCB.

• Copper Traces...the PCB version of copper wires used in Breadboarding
• Board Outline...the shape of the PCB board

To export .svg files in Eagle...

• Isolate TRACE or board OUTLINE images by showing and hiding the appropriate image LAYERS
  • Trace: Using the Layer Manager turn off all layers leaving only the “Top” (Layer 1) layer showing the interior trace lines. Under the “File” menu, chose Export > Image
  • Outline: in Layer Manager turn off all layers except for the “Documents” (Layer 48) layers to show the filled, polygonal shape of the board. Under the “File” menu, chose Export > Image
• File >> Export >> Image >> File Name (”Traces” and “Outline”) >> .PNG >> Monochrome >> 800 DPI

A script can be run to do all of this automatically...
