Help with Kicad

Hi I am making a PCB for my new amp using Kicad. But I think my Gerber files look weird compared to the videos I can find on YouTube. Can some one tell me, if the numbers on the on the layout will mess up the fabrication, or how to remove them.

Thanks in advance

Depends on the board fab. The fabs I use, seem to automatically delete graphical lines on the FrontSilkScreen (and BackSilkScreen) layers, which overlap the SolderMask layers.

You could use GerbView to display only the soldermask layers and the silkscreen layers, to get a rough idea of how much text the fab may delete.

I don't know how the text got there in the first place, so I don't know how to make it disappear. You may need to start Googling for "KiCad unwanted node text" and other such descriptions.

Those are D-codes. I think they're in all Gerber files. Just go to Preferences in GerbView and uncheck "Show D codes".

Gerber is actually a photo plotter format and the D codes are referencing different holes sizes in a mask, for exposing the photo sensitive resist or even photographic film in the old days. They won't appear on your PCB.

Thanks for the info. I guess a good day is a day where you learn something new

Its probably just for information and doesn't appear on the final pcb.
PCBCAD51 shows net names on tracks in PCB entry but they don't appear on the final pcb. Its just for information.

The numbers are D numbers.

It's the daraformat turned visible by the viewer.

Meaning, everything is ok.
