This Pen Holder can be used to draw circuit boards with an etch resistant pen and is printable on a RepRap. Besides the RP parts all that is needed to operate it is a rubber band which holds the pen in place.
The CAD Models are not available at RepRap but can be downloaded from Thingiverse
Gerber RS274X to GCoder Converter
A little Java program to convert Gerber RS274X files, which can be exported from Eagle or KiCad, to GCode.
The code can be downloaded via subversion:
$ svn co http://ionscale.com/svn/repos/reprap/gerber2gcode $ cd gerber2gcode/src $ javac Main.java $ java Main pcb.gerber pcb.gcode Gerber RS274X to GCoder Converter for RepRap's Input: pcb.gerber Output: pcb.gcode Pen Width: 0.7 mm Offset X: 40.0 mm Offset Y: 40.0 mm Drawing Height: 1.8 mm Freemove Height: 3.8 mm GCode file generated succesfully !
This software is still in a very early stage. The pen width, offset and height parameter can be changed at the top region of the Main.java file.
