More issues in PCB Design

Kerala's gerber2png does not allow download

Tried the other fab program to create images from gerbers, but I have no idea how to use it. Therefore, I went back to inscape. BUT the workflow is quite annoying: in Kicad plot as pdf. Import in Inscape. Manually change the background. Export as png. Process can be shortened and less prone to errors if we can avoid the manual background change.

Alternatives to inverting images

Solution 1: Inverting button in Mods CE: sometimes the images are not read correctly and so can not be inverted.

Solution 2: Inverting in Inscape. Sometimes does not work. For some reason traces sometimes will not change colors.

Solution 3: Inverting on this website. Works smoothly but crops the image to minimal size, effectively changing the distance from the margin. Mods CE does not allow to change the offset of the pictures, therefore the milled PCB would be useless. Second more relevant problem: The inversion is not precise!

Solution 4: Create an image background in Inscape, then invert on previously mentioned website.

The edge cuts are shown above the traces after processing in Mods CE

Solution: several people in the lab had the same problem. They milled their PCBs anyway and it works. This error seems to be based on the 3 dimensional graphic preview of Mods CE.

Traces too thin

I forgot to change the width of the traces in kicad. Therefore I milled it 0.2mm instead of the standard 0.6mm. This resulted in the traces being so fragile that they disconnected quite easily (one broke after accidentally washed in washing machine). Learned my lesson, will not do that again.
