Hi Jazzcnc,
Hopefully I am getting somewhere now!
I opened cut2d and created a new job, then I imported bitmap image (my png logo)
used the trace bitmap tool and hey presto I had an image that can be exported as a DXF file which I can then open with Sheet Cam for cutting.
Thanks very much for your time and knowledge in trying to guide me in the right direction, it's very much appreciated!
No doubt I will be back again when I start my next project.
