  • Y axis longer after upgrade.

    We have recently upgraded to Pc-Dmis ver.3.7mr3.
    For some reason my Y axis is loinger -
    I have a fixture with two alignment bushing spaced at 2000.000mm.
    After the upgrade the machine reports the distance between them at 2000.300mm.
    Is it possible that the new version is not reading the error map?
    Is there anything i should adjust in PC-Dmis setting editor?

    Any info greatly appreciated.
    Thank you.

    What version did you come from? If you came from something OLDER than V3.5 (pre-V3.5) then NO, it is NOT reading your error map.

      Thank you for a quick reply.

      The upgrade was from 3.7 to 3.7Mr.3
      That's why i'm kind of puzzled as to why would the reading change?

      Thank you.

        Well, it might depend on HOW you did the update?

        1) Did you install OVER the existing version?
        2) Did you make a COPY of the existing version, then install into the copy?
        3) Did you install into a virgin directory?

        If you installed into a virgin directory, that is 99% likely to be the problem.

        If you installed OVER the working copy, well, SHAME ON YOU! (really, shame on you). Your safest bet is to make a copy of the entire working directory, then install into that copy. If you installed into your working copy, well, you can see, you really have no safe way to get back to it.

          It was installed into a new directory named Pc-Dmis3.7Mr3
          The really weird thing is that now, even if i run the older version the measurements are out. Something has changed and i have no idea what.
          Coud it be that the error map is stored in the controler and new version somehow changed the PC-Dmis settings and it now does not read the map?

            I would bet that if you installed it into a NEW, blank directory, that the registry got changed and that is wher eit turns on/off the table map. Also, just to be on the safe side, do NOT use -+/* in your directory name. My installed, working directories are:

            PCD32063MR3
            PCD3205MR3
            PCD3500
            PCD3500MR1
            PCD3500MR2
            PCD3500MR3
            PCD3700MR3

            How you turn the table map back on wil ldepends on your controller. The SHARPE32 is different from the SHARPE32Z which are different from any other controller. Also, some controllers from older, updated machines, will ahve a seperate directory, NOT inside the PCD directory, with all this stuff in it.

            There are 2 places you need to change the settings (in the SETTINGS EDITOR) to get the comp on for the Sharpe32 controller, but my machine is running right now and I can not access the settings editor.

              The controler we have is DEA (Brown & Sharpe).

              I assumed that new software stores the map in registry. Is that not correct?
              If it's stored in the controller, should not the new version read it from the controller?
              I'm confused here.
              Thank you for all the help so far.

                Mine is a DEA, the files you refer to are in the PCDMIS directory. If you copy the original directory and install to the copy as Matt recommends I think you'll be fine.

                  I moved the files to pc-dmis (after backing it up to cd) directory.
                  I still experience the issue. I wonder if i should change anything in pc-dmis settings file to enable it to read the error map. It seems as it is not reading it at all.

                    We had a concern about whether or not the comp files were being read correctly and B and S told us to look in the settings.

                    In the settings editor look for the Sharpe 32 controller and click on it.

                    Look for VolCompMethod

                    Value should be 14 for a Sharpe 32.

                    If Value=0 then machine is NOT looking for comp map.
                    if Value=1 then machine is looking for the wrong file for a Sharpe 32

                      Hi,

                      Thanks again for all the help.

                      I have looked into settings and under VolCompMethod my settings are set to 1. Could that be the issue.
                      I have also looked in settings for the previous version and it seems as it's set for 1 also. I have also ooked in long not used 3.5 version and i can't find the VolCompMethod value in there. Should i try to change the value to 14?

                      Also, i do not see Sharp 32 in there - all changes are under leitz controler

                      Thank you.

                        What is UseVolcomp value used for? Mine is set to 0 in the 3.7mr3 settings.

                          I think you may have the correct number. 14 is for a Sharpe32 controller and that is not what you have....

                            I belive i do, but i'm not sure.

                            I also been comparing the settings in all my versions of software.
                            There is some differences.
                            For one, the software is looking at compens.dat file instead of comp.dat and also UseVolcomp is set to 0. I also compared both comp.dat and compens.dat and they are exactly same (i used beyond compare 2.0).
                            I'm kind of lost now. Hope i can resolve this soon.

                              More of what i have found out.

                              The controler type we have is DEA and the interface is B&S Leitz.
                              I wonder if the machine should read the error map from the controller and for some reason it is not.
                              When i place the compens.dat file in the Pc-Dmis3.7mr3 folder and enable (change from 0 to 1) the UseVolcomp setting under Leitz menu in settings editor and than fire up the pc-dmis it comes up with the message that is saying the "Volumetric compensation is being used in both the controller and the pc"
                              When i remove the compens.dat file from the folder and leave the UseVolcomp at 1 than i get an error "Invalid VolComp configuration, volcomp will not be used"
                              When i change the UseVolcomp back to 0 it's all ok (no messages).
                              Is there any help file explaining as to what all those settings do.
                              I know that if the error map is read from the controller than i would need hyperterminal to access it. For now i just want to verify if it reads any error map at all.

                              Thanks for all your help so far. I will update this post if find anything else.
