Hi Windell,

I made the modification factors 10000 and 10 to setup higher speeds.

Through step_scaling_factor = 0.5  now I can use the standard svg-files without modifiyng 
the documentsize to 6400×1600. And this did even cover speed-adjusting.
Thank you very much for the tip.
As I could test now higher speeds. It turned out that my arm is not stiff enough for speeds of more than 1200 steps
per second. (which means 2400 steps per sec for a 400-fullstep/rev motor)
I found another thing that is a bit annoying. Somewhere in the sourcecode I read that 
if option start centered is chosen the first line has to start at a centered position.
What’s so hard about calculating the difference between a first position with ANY coordinates
and the centered position?
As I started to modify the code. I have several ideas how to polish the code 
remove hard coded factors that they CAN be replaced through parameters
if parameter not found use hardcoded default value.
How about using the *.INI-file standard Identifier=value?
I’m a delphi programmer
does python support INI-file-reading writing with commands or would I have to write everything from scratch?
changing move-direction in the manual register through +- is annoying. 
How about more buttons to just do a click on each command?
Where is the GUI of the eggbot control defined?
How much evolution of the python-code would you allow?
should it be 100% downwards compatible or would you allow changing some things?
best regards  
Stefan
