Hello,
The Ronchi was only the first test, I was going to move to foucault and figureXP later.
I see scanners are as cheap as chips, a little more info on how you went about your setup would be great. At this moment I was going for a dial indicator at 0.001 and $130 posted. Main reason being is that the figurexp goes to three decimal places.
The scanners are from $30 though.
