    Corel draw 8 ships with a program called "ocr-trace" which will allow you to import any picture file and convert to DXF for editing/toolpath programming in your favourite cad program. Then you can use the free ace converter from yeager automation to get to g-code.
    You can get ace here

    ullbergm, I was thinking about one of these today..
    How has it been going?

    I think I might have the boss (AKA Wife) to go for a full setup..
    If you need an image change from Raster to Vector put it on the FTP so I cna change to a DXF or any other format for you.

    thanks

    Cool, thanks
    What software do you use?

    What codec do the video's use. I only get the sound, no video.

    To be honest, i dont know.. they are straight off of my FujiFilm FinePix 2800Z.
    I'll let you know if i can find out.. they played without any extra codec on xp so i never had to find out..

    I take that back, i did install quicktime.
    I've heard that quicktime may be the solution to playing the mpegs. not 100% sure thou

    Default Movie

    Movie worked fine for me. If my player doesn't have the codec, it finds it automatically on the internet, updates, installs and plays.

    What software did you use to program the gcode for cutting the letters? What ipm did you choose?

    I'm running at 9 ipm which is the fastest i can go right now.

    I still dont have a good solution for converting the text to gcode. The same friend that helped me with the celtic knot pattern made the gcode for me.

    Do you have any suggestions for a good software in the couple of hundred dollar range?

    I'd like OneCNC but i cant find a price other than
    From www.onecnc.com
    Our CAD-CAM solutions range in price form $1,000.00 USD to $7,000.00 USD so we cater for all users whether you are a home model maker through to a high precision mold maker or toolmaker.
    and that puts it outside my budget

    i haven't tried ocr-trace yet, dont have a copy of corel draw, but i may give that a shot.

    Is there a limitation on your speed? I would spend money on upgrading the driver or whatever is holding down the speed before buying an expensive cad/cam program.

    I use the corel OCR program to scan client line drawings. It is only a start. After cleaning up the scan and converting to dxf, I open in OneCNC, set a new layer on the drawing, and place points at all relevant places and intersections, then make a new CAD drawing as an overlay.
    The OCR settings take a while to figure out, the lines can end up jagged. Also, my scanner can alter the scale of the original drawing, so everything needs to be dimensioned before I start or I can be off by up to 0.1 inch. On my system, the scan is saved to a bitmap, the bitmap is opened in Corel OCR, vectored, saved to dxf, then opened in OneCNC. Like translating from english to french to korean.

    I'm debating which one is more important.. i'll know more after i getahold of corel draw.

    I'm not using the driver/motors that cheap cnc usually ships with, i already had a stepperworld controller.
    i'm looking at making a chopper circuit instead, that way i dont have to use power resistors and loose power there.

    sounds like a lot of fun

    A chopper will give you more speed but it needs to be combined with a higher voltage. For example a unipolar controller on 12 volts with resistors will give you roughly the same speed as a chopper on 12 volts. A chopper board is really nice because you can go to the higher voltage without having to buy and try to cool those big resistors.

    I wish it wouldn't crash.
