    1) Clean all drives and ways and scales
    2) Replace a controller
    3) Replace a drive
    4) Replace a drive belt
    5) Tighten a drive belt

      Your CMM has to move from A to B in an allotted time. If it doesn't you get an "excess lag error". As usual Matt is right start with cleaning, check for anything obstructing the movement of the CMM etc

          Low or obstructed air pressure can cause that too.
          When in doubt, post code. A second set of eyes might see something you missed.

            Usually, just cleaning the scales will take care of the problem - but, it could be the encoder getting ready to check out.

              Also listen for air leaks I had this problem in the past and the seal around my counter balance was leaking air creating a low pressure conidtion past the air

                The encoder is what got me. Cleaning is good though and the first place to start. We had our CMM completely rebuilt a couple years ago and it was a nightmare. They treated us right but it was still a mess. I hope it is just cleaning. repacing an encoder is no biggie but not cheap.
                One way to maybe keep from replacing it is to take the encoder bearing out for whichever axis and clean it thoroughly with a stiff brush and alcohol. This helps and maybe all it needs. Just be careful about putting it back in correctly.

                  Thanks for all the input. It was due to the fact that there are offices over the lab and the walking is creating vibrations and causing ceiling tile dust to fall on the cmm. After wiping it off, the problem was gone. I knew that the encoders shouldn't be the problem and there was no air problem. The cmm is fairly new and has been taken good care of.

                  Thanks Again,
