Strangeness indeed when I choose a tool smaller then 1/4 inch to cut a circle it cuts eliptical ... i have tried the code in cncsimulator and it performs a circle. Here is the code ... any one have thoughts ? It also cutting larger then what is in the wizard ... 1 inch diameter is like a 1 inch radius instead almost twice the size.
