length checkout trouble

We do a length check out every morning. It's always within the allowable
0.059mm. Today we can't get the range or standard deviation under around0.200mm. We had the same trouble a couple months ago and had the ROMER repaired. For the last two weeks the length checkout was fine, but today bad numbers. We've cleaned everthing - magnets, table top, length bar, etc.
We've also reloaded the arm specs.
Does anyone have any ideas what might be going on?
Thanks...

Look at the arm to see if you can see any obvious damage from being hit or dropped.
You can call romer tech support- they can walk you through some diagnostics in CIM CORE utilities (arm aid) that checks the boards and encoders.
