I have made a small adjustment to my Helixa spindle position and now I receive Extensometer Failure Error?


It is more than likely that the belt tension needs a little more adjustment.  See picture below:  If you insert the Allen key and turn Anticlockwise it will increase the tension.  Increase the tension in small increments, only turn the screw ¼ of a turn at a time until the error does not occur after running your tests.
