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.
Profile 2.tap.zip
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 curveLast edited by Clive S; 09-07-2016 at 10:59 PM.

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?

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.

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,

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.Gerry
