Vectric Aspire makes a mess of a circle?
Been learning Aspire for some CAM work, it seems to have a bug with simple circles where it generates G-Code with hundreds of straight lines?
Here is a simple test file - it contains two paths, first is a square with 10mm radiused corners which works perfectly. The second is a simple circle and as you can see it has used loads of straight lines this time.

Can this be fixed at all, I am using the post for Mach3 with Arcs and ATC.
Thanks

Dave can you post the Aspire file up?
I have just drawn a simple circle in Aspire and put it through the MAch3 post without any problems.
Have you done the cad in Aspire or imported from another cad package there is a command to close vectors with a smooth curve

Daft question, maybe, but did you draw the circle in Aspire or import a dxf from elsewhere? I had similar problems a little while ago because I had saved the dxf in the wrong version so it ended up as a series of line segments rather than arcs.

Hi
the file was just a quick mess about for testing the motion on my mill conversion project.
It was all done inside Aspire.
File attached

I just made a similar file in my CAD app and converted it in Aspire and its just as bad, converted in SheetCam and its perfect - about 15 lines of code :)
Seems to be an aspire bug?

Dave when I draw a circle in my Aspire it is fine when I did another circle on your drawing it is also fine. Did you draw the circle in Aspire
The post I am using is Mach2_3_Arcs_mm.pp
Re: Vectric Aspire makes a mess of a circle?
Yes i drew it in aspire, same post here although i tweaked it a little to suit my machine but only in the end code i think.
Aspire does the same thing when i import a circle from my CAD app.
Re: Vectric Aspire makes a mess of a circle?
I'm not familiar with Aspire but most CAM applications have an option for lines or arcs as some old controllers don't support arcs.
If you select a "lines, not arcs" output option in CAM the results are as described,

On reading further. I have read that if you stretch a circle in Aspire it changes to segmented lines.
Re: Vectric Aspire makes a mess of a circle?
You must have modified the circle in some way.
If I export g-code for your circle, it uses G1 segment.
If I draw a new circle over the top of your, and export g-code, I get G2/G3 moves.
