"Failed to detect a focus position for feature <featurename>"

vpt.se
What can cause this?

Tried
- new probe files
- different Z-heights
- different lightning
- different backgrounds
- different surfaces

I can visually "see" that it does focus very well, during the autofocus phase - however, it does not seem to "lock" or "detect" this...
CMM-V (HP-C-VE) in 2016.0 SP1.

Ideas?

  • - Yup, I have that artifact and it was with that artifact the tech tried to calibrate to but it couldn't achieve focus... I think the probe in the probefile listed as "CMM-V", not "CMM-Ve" (if there is any difference between the two, probefile-wise).

    I have not tried it myself - yet.

    I had both CMMV, then CMMVe, ther's a difference of size and of distance of work (not sure for this point) and a difference of image quality.
    I don't think Hexagon still sale the first one.
    One of my old posts on the vision forum was about the star stylus which is used to calibrate angles : why is it the same stylus while the cmmv are different ????????

    There are some utilities to check some parameters without pc-dmis, some wires to check, options with framegrabber, compatibility with 64bits..... (for example, falcon board can work in 64, not the matrox).
    Did you look at the ftp : ftp://ftp.wilcoxassoc.com/Hardware/Vision/ (I'm unable to add the link as a link, it adds http before ftp !!!!! Disappointed (but it seems to work after posting Slight smile
    There are some (old) informations, but always usefull !!!!!
