Which version of Visual Mill are you useing? Back when I had version 3 it crashed alot on 2d machining. Put your file up here and I can try it out and give you a step by step on how to do it.

Yes. To cut a shape out you'd use 2d profiling. Be sure to select your regeions before using profile, or it won't do anything.

You can tell it how many passes to do (depth) and weather to cut on the left or right side of your shape.

Ya Thanks i got it to Cut but the result is all jagedey ???

Thanks

[MrBean]

Hmmmm. I'm not sure why that would be. Visualmill will make the gcode to the exact shape of what you've drawn. So, unless you drew it all "jagedey" I can only assume it's your router setup/mechanics. Any chance you could post a picture of your cut out item?

[Biggermens]

Thare is the file i am working on you can see the art is not jagedy but the cut line is
i had to put .zip at the end so i can up load it

Thanks

Here is the Dxf i did with corel draw

[MrBean]

I looked at the first (VMP) file that you posted. In the Geometry list, I expanded the curves menu, and they are all polylines, so they will be jagged.
Can you save the file with arcs instead of just polylines? That would fix it.

[Biggermens]

Do i have to redraw the art work ??

[MrBean]

That depends on what else you have the file saved as, other than the dxf you posted here. I've never used Coral draw and don't know what it's native editable fromat is. e.g. PhotoShop's native format is .psd

If you only have it saved as the dxf, then I'd say you need to redo it and save it with arcs.

I'll upload a similar dxf here in ~10 mins. You can load that into Vismill and see that the geometry contains arcs. Yours does not. So you need to either, resave the original file as a .dxf with arcs, or redraw the text and then save as .dxf with arcs.

[MrBean]

Check this dxf out in visualmill. If you expand the "curves" item, under "geometry" you'll see that it's made of arcs and polylines.

This should give a smoother output.

BTW. The simulation of the cutting is always rougher than it actually comes out of the machine. Unless of course your machines max resolution is really low, like 1mm.

You can also set the facetting preferences and the machine accuracy outputs under preferences. But always try to work with arcs instead of polylines.
