I saw post in this general purpose forum where this guy claimed he asked chatgpt to learn about cnc-milling machines and material properties and produce g-code to mill a gear. People were replying "I dont understand, but thats cool!" etc. I checked his code and it did circle with G3 and then it did "finishing pass" which was also circle by rotating the chuck or A-axle. When I asked him about it, he just said "Oh, I didn't look at the code"
