Thanks for posting those. They were helpful, sort of.
Here is the thing, we also need to see the line before and after a G02 or G03 move to really check your code. Also it is important that the lines you show us are lines that cause an error.
My instinct is that the code is correct. There is nothing wrong with the lines you posted. Those are what arc commands look like when using radius style programming for arcs.
Here is what I would do in your situation:
Give the Laguna folks a call. Email them your design file and let them know you are using a .25 end mill. They are a training facility for Vectric products so have them post your file, test run it on their machine and send you the cnc code for testing on your machine. That will tell you if it is something specific to your machine.
Without seeing more of the program I am suspecting that you may have set some cutter compensation numbers that result in the tool not being able to cut the radii. That is a pure guess, nothing more.
