Trouble withText for Engraving to GCode

Hi,
I want to konvert a String with a truetypefont to gcode. I tried the truetype-tracer which works fine but I couldn't find an option to specify the size. Is there a way to scale the gcode, or specify the size of the font.
Secondly I tried using Deskengrave for windows which is a wunderful easy tool but it only gives dxf and nc files which can't be read by emc. Is there a way to convert them?
The third trial I did was using Inkspace and the gcode converter. I got an error msg and no gcode:
Traceback (most recent call last):
File "/usr/share/inkscape/extensions/gcode_tools.py", line 38, in <module>
_ = inkex._
AttributeError: 'module' object has no attribute '_'

hope someone can help me
or if someone can tell me a way to convert a ttf string in g-code with a specified size(letter or string size)
thx

Hello,

the generated ngc program from truetype-tracer has parameters in every line after the X123*#1 and Y456*#1. In the header of this programm is one line in which you can define this parameter like this #1=123.456 this is your scale factor.

good luck

sorry for my english I'm german

So I just open the ngc file with a texteditor and change the parameter #1?
Is there a list with all the parameters and what they mean?
Thanks for the help.

You can answer in german if you like too.
