Identical results laser scan after laser scan.

My programs give me identical results for the auto features that are extracted from the COP. The first time the program is ran everything is fine, but when ran again which includes COP empty command and new laser scan to make a new COP I get identical results and my 3 point COP-to-CAD (1000pt, 20 interations refinement included) alignment gets screwed up. The results are identical out to 5 decimal places. If I run the program once, then close program and close PC DMIS 2014.1, then start PC DMIS again and load the program again I get repeatable results that are good and they are not identical. Anybody have a idea whats going on here? Also PC DMIS runs slower and slower as the day progresses. I'm using 2014.1 with a Romer Arm and RS2 laser probe.

  • My response here probably is not going to be very much help as I have never ran into this problem in 3 years of running PC DMIS ( 4 different versions ) with an RS1 laser.

    What kind of auto features are you trying to extract? I build almost all of my features from individual auto points.

    I have had PC DMIS go right past my COP and make the nominal CAD data my measured data, although this happens far and few between and it is usually only 1 or two points, not the entire program.

    My next suggestion would be to contact Tech support, even though I have never really gotten any help from them. There is probably a check box checked some where in one of the many menus that shouldn't be checked.

    One other possibility would be to get a settings file from some one and see if it changes anything. This would wipe out any settings that you have and your tool bar and screen arrangements. I am not even sure if it is possible to install some one else's settings file on your machine, but I could send you my settings file.....worth a shot. sstaral@wafco.com


    As far as PC DMIS running slower and slower, I believe this is common. Some times closing PC DMIS down and restarting it takes care of this.
