Edit font to be plotted

Hey there!
i want to edit an existing font that it will be possible to plot it. In the font information I copied the bold master, renamed it into cut. Now I changed the first glyph (A). When I want to export it as a ttf for testing it says:
Es gab ein Problem beim Konvertieren des PostScript-Quell-Fonts. (Regular)

Can someone help me?

Or can I send the glyphs file to anyone who can try to export for me?

Can you send me the file?

Unfortunately I can’t upload a file. The system refuses because I’m a new member…

Please send a dropbox link (in a direct message if you don’t like to share the file).

I had a look at your file and it exports just fine for me. Can you try the latest cutting edge version (activate it in Preferences > Updates)?

now it works! Thanks a lot for your help!
