PCB CNC: Unterschied zwischen den Versionen

Zeile 58:

* Hotter soldering is required, as there are no thermal pads.

~~== Metaboard*.sh ==~~

~~Metaboard are some bash shell scripts, that will automatically create cnc-paths in the form of gcode files. The starting point is the eagle .brd file.~~

~~Download of the files: [http://kariert.org/files/metaboard3/ Here]~~

~~Usage: metaboard3.sh <options> filename~~

~~filename: eagle brd file to process~~

~~-double: create a double sided gcode~~

~~-0.8: use a 0.8mm mill head instead of a 0.6~~

~~-tight: only offset by a distance of 0.3 mm~~

~~-filled: the eagle board file has a filed dimension area instead of lines~~

~~It calls a couple of external programs:~~

* [http://www.cadsoft.de/ Eagle]: to output the gerber files of the top and bottom layer

* <del>eagle: to call an ulp-program "drillbernhard.ulp" that outputs the drilling and cutting paths.</del>

* [http://www.cadsoft.de/ Eagle]: to output the excellon drill files.

* <del>[http://www.mit.edu/~vona/Visolate/Visolate-info.html Visolate]: To create the isolation paths. We use an unreleased version, that is scriptable.</del>

* Meanwhile, [http://sourceforge.net/projects/pcb2gcode/ pcb2gcode] was adopted and is used.

* [http://code.google.com/p/grecode/ grecode] To mirror the board for second side. (Grecode was created especially for metaboard.sh by --[[Benutzer:Bkubicek|Bkubicek]] 09:55, 26. Jul. 2010 (CEST))

~~While these are called, <del>a couple of windows will pop up and hopefully disappear again.</del> only shell output will be produced. you will get some debug images also in the current directory.~~

The outline is also milled like the bottom or top side. No extra step is needed!

== ~~Usage~~ ==

== Workflow using eagle and metaboard.sh ==

The workflow splits into the following points:

* Preperation: create an eagle brd file, copy it

Zeile 142:

Removing the boards works best by using a twist motion around the z-axis. A brush should be nearby to clean the grooves.

=== Metaboard*.sh ===

Metaboard are some bash shell scripts, that will automatically create cnc-paths in the form of gcode files. The starting point is the eagle .brd file.
