| I'm having the same problem. It has something to do with the Post Processor settings X,Y,I,J. Does anyone know the right tokens, variables, and movement scripts settings in DesKam to get #2 below to look like #1.

| This is just a guess, since I don't know your software at all, but change your maximum arc command to 1/2 or 1/4 of a full circle. This will create endpoints that are different than the start point, which is what makes a full circle arc command seem a bit "strange" to your controller, because it is already at the endpoint position named in the full circle command.

| The same general principles apply. There are several different permutations to guess through, to get the proper settings for your controller to recognise arc output properly. As I pointed out before, you should change your maximum arc output command to 1/2 of a circle. Also, you need to discover whether the I and J components of the G02/G03 command are to be incremental or absolute position values. These settings might also change depending on whether your main program is running in absolute (G90) or incremental (G91) mode.
