Making some progress with preparing to cut better signs for Bridge Rectifier. Researched stencil fonts, as the only way to make a sign from a single sheet without parts of the letters falling out. Found this review of fonts: http://www.creativebloq.com/typography/10-top-free-stencil-fonts-2131956
Mixed case fonts include: mixed case fonts - ag, scriber, kaine, urban sketch, stardos. I chose StarDos and downloaded, then dragged files into Fonts directory, found by Control Panel > Fonts. So, text part of sign looks like this:
Then set about trying to achieve the same with BR's logo. Eventually discovered that the 3 characters in the outline (~, +, -) are all strokes (size 1) with no fill. By selecting each individually (Ctl & Select arrow), I could create a stroke outline by first converting the character to a path, ie select 1 character, then Path > Stroke to Path (instead of Object to Path), then change fill to contrasting colour, add stroke, reduce thickness from 1 to 0.3, finally remove fill.
Managed to create ~ and - as outlines that the laser cutter can cut through. With the +, the vertical and horizontal rectangles intersect, which means at the 2nd pass, the cutter would be burning through nothing. Instead, it needs to cut all around the outside of +. Here's where I've got to (the red background is just for contrast):
I've tried getting the difference between the vertical & horizontal, but it deletes the whole horizontal, not just the middle square. Any tricks you can think of, @Freddie?
