Path missing lines for engraving

Post by devils4ever »

I'm having trouble with Path generating the correct G code for an engraving operation. It seems some of the vertical lines are missing. I've attached a sample. Thanks!

Such defects are often caused by defects in the font. You can check it with FontForge, another OpenSource program.

Usually, fonts, are not meant to be used to engrave, in fact there are some font developed specially for engraving like:

http://www.atelier-des-fougeres.fr/Camb ... fonts.html

That were developed to simply have "polylines" that do not interrupt where is not necessary, avoid "double stroke" and unwanted crossing.

From what I know they are free to use, sadly the original site is not active anymore, but in the zip file there is some license infos, from what i know they are usable without paying anything, and despite the name (CamBam is a paid program) they are not related to the product, but a work of an user.

I have use them and they are good, read advices in the page, (The page is independent from the program and his made by an user and CB forum moderator, very nice fellow).
