Prompted by Evan's post on his CNC and engraving plus some 'emails' we both have had, actually PM's as ower two ISP must have a spat on with each other and we have problems seeing each others files.
Engraving fonts really need to be single line fonts or stick fonts to get uniform shape. Unfortunatly most windows fonts are true type which have a thickness.
This is handy if you engrave such as the photographer plate that Evan did but not for simple work.
Evan commented to me that V Carve didn't engrave stick fonts Ok as it missed bits out wheras it's not that but the way it handles varying width toolpaths, A lot like his picture of the dawg.
This is Evan name done in V Carve in Script font.
Now as we know Script is quite fancy but this looks terrible, it looks like a dyslectic spider that's fallin into an ink well.
The reason for this is the toolpath has been optimised to work with the Z axis so in effect it's a 3D file.
This is the same file / picture showing the 3D toolpath.
And this is a close up of the toolpath with the fill switched off so you can see it better.
You may need to stare at it a bit to get perspective, the shapes are valleys and note the sharp end causes by the tool retracting so that only the tip is cutting to give the sharp corners.
By altering the depth it also alters the width to make the most of a fancy font such as Script.
