I’m not sure if I’ll be in this week but I found it quite easy to use without anyone showing me.
I suggest to start with you get a scrap of fabric and use the built-in tools in the machine to embroider something simple e.g. your name. Then you’ll get the hang of how it works before you get into anything bigger.
How have you created your design?
I’ve used https://inkstitch.org in the past to get a vector design in a format that the embroidery machine will understand. But beware that if you want this to look really good, it’s not a straightforward operation to transform vectors to stitch. Ideally you want to break your design into parts and decide what type of stitch to assign to each, otherwise they’ll all be embroidered in a generic way that doesn’t look so good. The Inkstitch website has got some good documentation and tutorials
