I like that you ask questions Toogie, I don't like when I am uniformed and can not answer and in your case, I can not answer. But, I am so looking for new projects from you with the "SVG touch or whatever files". You make the best stuff!

I have had a scan and cut for 18months but honestly I haven't used it

I do have one. And yes you can use SVG files, but they have to be converted on the brothersite ( see link) because Brother uses FCM cutfiles.
I did use mine for cards and texts of vinyl. I'm still experimenting, don't have it that long. But it's fun for another kind of craftwork.

I have a Silhouette cutting machine and the software can use svg-files as cut-files. I originally bought it, just before the brother scan-and-cut was launched to cut appliqué pieces to use in (appliqué) designs, but so far I have used it for card making, cutting iron fabric to be ironed on my GDs hockey shirt and bookbinder's linen but not yet for fabric.
