not sure if this is the right place to post.
Many footprints display the component value on the F.Fab layer (yellow color by default).
PCBNEW always displays the values, regardless of the F.Fab checkbox in the Layer right panel.
Remove the F.Fab layer from the project or change the layer of the component value makes no change : the value is always displayed.
The only workaround I found was to change the value visibility prooperty to “invisible” and then uncheck “hiddden text” in the renderer panel.
Issue is with kicad 4.0.0 and 4.0.1
Ah, now that IMO is a deficiency in Kicad. There are decisions made in the Plot dialog, so you never get a WYSIWG view of the final plot. What I do is generate Gerbers, then view them in gerbv to get a check of the output board layers. Even that is not quite right, but it is close.
