No, I have never used a probe
My level is somewhere between beginner and almost beginner .
I have made some watch buckles, machined some trial watch cases from Aluminium with just flipping over using a ''stop'' of sorts, that was close enough to prove the tooling and tool paths etc, but not something that would be considered ''done''
I have enough stock in Aluminium for 15 more trial pcs and enough 316 stainless for the same. By that point I want to have the final tool paths, tools to use and setup on the machine.
Youtube has been a big help, taught me most things and forums also.
I will spend the evening as you suggest Youtube!
