    Have been trying for a couple of days to convert this jpg Logo to an stl file using online software but not having much luck in creating anything of use. Can someone suggest a converter that works without learning a whole new program, I am too old for that

    No such program exists.

    While there are plenty of programs that convert the various shades of gray to different heights, this really doesn't work well with normal photos or drawings.

    Have you tried this on?

    I tried it with Cura, here is the result https://www.dropbox.com/s/rfjhhmd2fm...alien.stl?dl=0

    Not brilliant, but you may be able to tweak it.

    Many thanks, looks brilliant to me compared to my efforts.

    Estlcam works Ok with it and I will try and find time to try it tomorrow, Estlcam estimates 16 hrs

    If not too cheeky and stressfull, would it be possible to increase the depth a little and remove the random stars that surround it

    You can download Cura for free and it is fairly easy to use. I would use a photo editor to remove the stars on the jpg and then load it into cura with the lighter is higher option. You can then resize it - I don't know how big you want the end result, but the one I did just fits on my 3D printer.
    If you struggle with it get back to me, but I am busy today.

    Cheers,

    Rob

    Thanks again, I did download Cura but it only seems to run on 64bit computers as does Fusion, I am only running 32 bit and am reluctant to change as my Acad 14 does not run on 64 bit.

    I can fudge it a bit by changing the Z scale on my mill and I can sand off the pimples, the pimples do add quite a bit to machining time.

    The scale is perfect for me, I am not in any hurry so if you can help when you have spare time would be great. I will see if I can remove the pimples/stars in paint.

    Cheers

    Had a go with Paint and have removed the pimples, I thinkClick image for larger version.

    Hi John,

    The mystery pimples are single white pixels, which are difficult to see. I have blacked off the major stars with 'Paint' but the little ones are everywhere.

    If you want to improve the doctored version and send it to me, then it only takes a couple of minutes to convert it.

    Cheers,

    Rob

    Hi Rob

    I did or thought I did remove quite a lot of pixels in my clean version, I wonder if the jpg format remembers them for undo purposes.

    Have had another session with paint, couldn't find any more pixels but used the flood option to see if that worked - Alien- clean mk2

    Also had a look with Irfanview @ 40 x zoom and couldn't see any, Alien-clean mk3
