sorry if I'm not much help, but Im in a simmilar boat, I have just got a Techno Isel CNC router, hopefully attached a pic of it. I need a cable but cant find the specification any where have sent e-mails to techno, isel and some one I think is a uk agent but have not had any reply from anyone.
I am also looking for the software and through lots of research have just become very confused, I have a maunal but it its in german so I cant understand it.
Have you looked on the techno website I think yours looks like a davinci ? I think, It wasent easy to find but there is a software page that you can down load the techno CNC interface from which I think would work with yours, mines older and I cant get it to install right, I think I may need the I5DRV software which is dos based again I think Im not acctually sure.
let me know if you need a link to the software page.
