I'm from Germany, so I'm sorry about my English.

I 've startet to use Inkscape & Scal for my cutting mashine.So I'm still an absolute beginner.
I've got a problem with my own design. I drawn on paper and then scanned with photoshop to bmp (I like it better, draw your own designs on paper). With Inkscape I' ve saved it as svg file. But when I open the file in SCAL, I can't see it. I only see an empty rectangle, but no motive. When I draw a design in Inksape, I can see it in SCAL. I think the problem has something to do with the scan. What am I doing wrong? I've tried it with the jpg format, but this was the same problem.
Can someone help me please?
Thanks in advance and sorry about my English.
love greetings Sindy
