KiBuzzard 1.2.0 works great with different inputs and fonts. Thanks. An example output on the F.Silkscreen layer:

I tried to use the F.Cu/F.Mask option but after clicking OK nothing happens. No entry in the log and the window seems to stop working (no preview updates).

I expected something like this:

Can someone confirm that this is(n't) working? Thanks.

KiCad 6.0.7 @Win10

It currently doesn't work the way you're describing. Although that output does look better. for the inverted options, IMO.

F.Cu/F.Mask option currently should create a label with the same contents on both The copper and mask layers.
