F-Engrave problems

[Swarfing]

In case any Linux users need to know it is

/usr/share/fonts/truetype

[cropwell]

I have pointed the thing to the fonts directory, but still no joy. I get a couple of messages about ttf2cxf and potrace not present/working, both of which end with the informative message '...Bummer' but I have no idea how to install these and get them running (presumably as background services).
The author's documentation for Windows installation - is just 'double click on the exe file'.

Anyway at the moment I am more pissed off that my Z axis has seized on the Delrin ...Bummer !
But I can fix that, it is, at least. within my intellectual capabilities.

Cheers,
Rob
