Hopefully not on the Jag you have posted pics of in the past
Anyway, a couple weeks ago I posted a note on how I introduced a tiny error by setting the ucs a tiny bit off when drawing the part and sending it to cam. I blamed everything, setup, Hamier, tool height gauge. …you name it. Then I stopped for a minute decided to run a different simple part to check everything in the shop. It ran just fine, so that narrowed the tiny error to either cad or cam setup.
When you don't spend a lot of time in these programs,its so easy to stumble on a step and cause a problem that will have you casing your tail for hours or even days.
