Hi,
Precision isn't very high, around 0.05-0.1 mm should be enough.
But I have no ideea how should I measure an distance in this range (few milimeters) and with such precision.
Do you have any links or some information about this subject ?
I think that sould be someting reflexive.
I have seen Laser Scanners on net it means that using laser sould work but I didn't found any explanation for a novice like me..
Thanks,
DAniel

Hi Daniel,

Maybe optical? Open loop Stepper motors? Closed loop servos?

What precision do you need?
