This is my cnc-isolate and cnc-drilling workflow for creating pcbs. | |||
The PCB have to be put on a plain-milled surface of at least 3 mm thickness, as we are drilling. | |||
The slightest bend (0.2 mm) in the PCB will probably move the "Gravierstichel" out of the plane where it would isolate. | |||
You need a 0.6 or 0.8 mm drill with a mounting diameter suitable for the Kress-"Spannzange", probably 3mm or 1/8 inch=3.1something. | |||
* Prerequisites: | |||
** download [http://www.mit.edu/~vona/Visolate/Visolate-info.html Visolate] | |||
** On Windows, that is | |||
** create a shortcut, respecting your paths, with the target ""C:\Program Files (x86)\Java\jre1.6.0_07\bin\java.exe" -Xmx1024000000 -jar C:\Users\bkubicek\Visolate.jar" and the working directory "C:/Users/bkubicek/Documents/eagle/LEDlampe/" | |||
** download and install [[https://java3d.dev.java.net/binary-builds.html java3d]] | |||
** save [[Bild:drillbernhard.ulp.txt]] into your eagle/ulp directory without the .txt extension. Its an ugly hack of the next original ulp... | |||
** save [[Bild:gcode.ulp.txt]] into your eagle/ulp directory without the .txt extension. | |||
* Create the Eagle board. Route only on Bottom Layer. | |||
* Output using the cam-processor, using the "GERBER_RS274" device, and '''only''' the layers "bottom","pads", "vias". Filename gerber_boardname. | |||
* Output using File->RUN->(ulp-directory)->drillbernhard.ulp . Layer "bottom", Mill and cut deaktivated, drill active,outputfile "drill_boardname.ngc" | |||
* Output using File->RUN->(ulp-directory)->gcode.ulp . Layer "bottom", Mill and drill deaktivated, cut active,outputfile "drill_boardname.ngc", other parameters are nearly irrelevant. | |||
* Then start Visolate, load the gerber file, make if fullscreen. press Fit. Fix Topology. Make Toolpaths. Output file as "isolate_boardname.ngc" | |||
* Then comes the joining of the three ngc files. I will continue writing in a couple of days. | |||
