n00b alert. Modifying existing kicad design and updating PCB

[jcpst]

I'm cooking up a project that uses a daisyseed. It looked simple enough to do it on stripboard. But since there's already great prior art (funbox), I thought it might make sense to pull that down and modify it.

I made a schematic in kicad the other day, so not 100% n00b, but still n00bian.

So with the funbox, all I'm doing is ripping stuff out. I have the schematic the way I want now. 3 knob, single footswitch & LED, mono audio I/O, and switched to a dual opamp.

Where I'm lost is the PCB. I thought it might make sense to modify the funbox one because it looks like there was a lot of work to get it to that point. But not really sure how to rip out the stuff I'm not using. Also not sure if it's easier to start with the neutered schematic on a fresh board.

RTFM is a totally acceptable answer to this too . I just thought I might get feedback like "you'll have a bad time if you do it X way"

Do you have the KiCad project files (talking about a set of files that ends in .kicad_pro/.kicad_pcb/.kicad_sch)?

If not and you only have the Gerber outputs, you're going to have to create a new board from your schematic.

If you do have those files, duplicate the entire folder and make that your working file. Open the project and then open the schematic from the project window. Remove all the unwanted components from the schematic. Now open the board file from the project window. If you did all of this correctly, you should be able to click on "Update PCB with changes made to schematic" button and it *should* remove the same components you removed in your schematic.

Thanks @Brett - it looks like I figured out what I was doing wrong- it didn’t have all the options checked, and it was generating my entire modified schematic on top of what was already there.

This looks ready for me to tidy up. Thanks!
