    The best I can say right now is make sure the the top of the material is 0 in Vcarve. It's past my bedtime

    Ok i'm still stuck.....I've tried messing with some of the z settngs in the programming process but am still clearly missing something...I thought perhaps i'd just do a simple gcode using text from vcarve….I used the word test and it did actually go into the wood, and cut but it cut some weird shape with a series of lines......what file type should I be taking to the cnc on the memory stick?......previously what I have been trying was .nc type...i'm just saving the toolpath after I do a design and that's what i'm taking to the cnc, should I be taking the .crv file?

    Mach3 should be happy with a .nc file. The code snippet you posted looked like it should work with Mach3. You can attach the whole G code file to a post if you change the extension to .txt. It really is just a text file anyway. I'll take a look at the file and see what it looks like in a viewer.

    I just almost feel like it's a setting of some type that I haven't done right, because I've tried other files and they all have the same behavior...the bit will dive into the wood a little bit then lift up and it will be trying to do the cutting about half a inch or so above the surface of the material. its like I don't have some type of parameter set right

    A half inch above the material is what the G code shows. I'm not sure what is causing the tool to dive to about zero, that's not in the G code. But Z0.5700 is where Vcarve is telling it to go. It looks like Vcarve thinks the top of the material is above 0.5700, maybe around 0.9500?

    I have never used Vcarve, but in general in any CAM program there is a way to set the working surface. I don't have time to download and learn Vcarve right now, but you might take a look at the online tutorials.

    The tool diving down might be the Safe Z setting in Mach3. I think it should be a couple inches or more above the work. Maybe at the Z home position.

    that is funny I just completed a tutorial for making a small sign in vcarve and followed their every step so I could look at the gcode to see what it looks like compared to what I have produced....thanks for your time and help.....if I figure this out i'll post it back on this thread...
