Which is probably easy to find and strip. I have noticed PcbNew is quite smart at Flood, and has a fill-by-outline mode, and if you select display outline modes, you can see the resulting paths.įor some reason, it seems to also generate a ‘join path’ to those outlines, but those may be tolerable, and maybe you could even strip them ? Looks like some experimenting will be needed. I also remember the InkScape is able to read pdf, isn’t it? I remember when I did a print (NOT plot or SVG export) of a layout and then used a pdf generator for the final destination, that the copper pours were poly-line zones and the tracks became tracks when loaded with adobe reader.
etch the result of that step after prepping the board.“burn” enamel away with laser where you want NO copper at all (probably toxic and if not careful damages the laser).cover copper clad area in black enamel paint.Just to make sure I understand you correctly, but what you write ^^ doesn’t match what that dude on instructables does: The idea is simply to cover the copper clad with spraypaint, and then use the etcher to etch away the paint to expose the copper you DON’T want to keep…Then, sit it in an acid batch, burn the copper and then run it through the laser again, this time etching away the copper you want to have exposed on the final board (pads for soldering, test points, etc.). However, this will burn the wrong stuff, so I try to take the negative colors, as show here, and then redraw the paths…This is a mess though, because it draws a bullseye right down the center of all the tracks…It looks like it’s on the right path, but still, unsuable: This is better because it has the negative-plot option, but it outputs the picture shown above.
Using the Plot Feature in KiCad with SVG output.This is no good, because there’s no negative option with this…And I can’t figure out how to get Inkscape to do it in post-process…Although, it does come into inksacpe as something I can turn into a path…The problem is, the path that it creates is the copper I want to KEEP, not REMOVE, so this is no good. Using the Export SVG from the File Menu in KiCad.Since the plugin is expecting a path, It makes no sense since I’d be trying to turn a full blown black rectangle into a path! I don’t know if you can see it, but it imports as two layers, and the bottom layer is what I’m trying to train the laser on (the black).
