I have a crappy feature to try and measure (Image enclosed). It's a R75.0mm milled arc, only about 4% (14º) of the circumference to measure on a fairly large rad.
I'm working from CAD and I'm starting with a fixed rad circle with 30 points (I have no scanning head), then aligning on that FR circle, doing a 2nd fixed rad circle, again 30 points and aligning now on that 2nd FR circle, then taking a 3rd circle, but least square this time, again 30 points. I'm getting fairly large errors from print, which may well be absolutely true, just checking if I'm approaching it correctly and my results are as trustworthy as possible?
Thanks folks
