RE: [CAD_CAM_EDM_DRO] EMC Continuous Contouring

Hi Andy,

I have used the following command to machine a circle

G03 x2.25 y 1.25 i-1.25 j0.00

which machines the entire circle without stopping.

To generate this code, I drew the circle in cad, exported to dxf and used
ACE to convert the dxf to g-code. There were some other positioning lines
in the resulting g-code file, but they were just positioning to the proper
xy coordinates for the beginning of the circle. This worked correctly in
EMC.
