Hello RGB LED 45 circuits

1. Open “cad.py”
2. Click on “input”go to fab directory, select circuits, “hello RGB LED 45mta.cad”
3. Click on output format
4. Select format for modella “.rml”
5. Select tool diameter “0.0156 or (1/64 inch)”
6. Total overlap is “0.5”
7. select the text line in the cad progamme ap pears on the right side of the screen, scroll down and select the “#dpi=500” and “#high resolution for machining” delete the # sign from these text lines.
8. Select contour to generate tool path and adjust XY position so that tool will reach to the initial position from where it start cutting.
9. Adjust “Z” height of tool by lowering down the tool close to the surface and loosen the set screw of collate so that tool can easily fall down on surface In such a way that it touches the surface and stands, then tight the set screws and click on the button “send to machine”.
10. The above procedure allows you to mill the inner circuit. Once inner circuit milling is over.
11. Change the tool with tool diameter “0.0312 or 1/32 inch”. set contour to +1, and Z speed is 0.5. Then press “contour” you will get outer boundary of circuit.
12. Go to the text file appear in the right side of screen, scroll down and go to the text lines “# cad .function=pcb.interior” and
13. “# Z=-0.5”
14. do not forget to delete symbol “#” from these lines
15. now you are ready to send the file to machine hit the button “send to machine”
