Welcome to the SeeMeCNC Community

Well, activated for just a few printer posts. Currently Prusa, RepRap, Bigrep, and the Autodesk Generic FFF post.

I modeled a test piece in Fusion, a 3" cylinder, 1" tall, with 3, 1" holes. The file size with normal slice settings was 17.5 Mb. After checking all of the appropriate boxes to activate arc recognition, the file size dropped to 6.5 Mb.

I haven't tried printing it yet, as I have to setup the printer configurations for my FT-5, running a Duet wifi.

Also on the list is to import a stl file, and see how it handles that.

It does not appear to do Arc fitting to stl files, It will generate G2s when using spherical infill. It's still early yet. MeshCAM figured out how to do that, but it did take a few versions before Robert figured it out.
