Good morning all,

I'll have to reverse engineer quite a few non-prismatic parts this autumn (3D contours, radius, etc) and gearing up for a cloud point system.
I do have a budget for this, however, and judging from the extremely HIGH cost of some relevant equipment, I find it hard to justify the expense for what I need to scan.
Another problem is the constraints I'll have to work within... e.g. probe's OD can't exceed more than 31mm on a critical part and most (if not all) of the probes within my price range are rather let's say bulky, some literally over-sized and heavy, others [no comments!].
That leads me no choice but to DIY my own 3D measuring probe (/end of short-story-made-long lol)

My question is: what sort of accuracy are you getting with the classic DIY 3 balls/3 poles type probe. I'm aiming at 0.01mm~0.02mm (which is by far the maximum my milling machine can cope with when up to temp).

Realistic? Share your numbers!
