Q: I get the Error on successive palpations

This means that while touching on the same spot on the mandrel for 3 times, the deviation from probing to probing is >3µm


  • Check conductivity of mandrel
  • check for impurities on the mandrel (grease, fat) clean it
  • Check conductivity of chuck relative to machine table
  • probe on a different place on the mandrel by rotating the mandrel a few degrees

Q: The wire does not start probing the mandrel, it moves to the opposite direction or directly to the circumference of the mandrel

A: The Parameter “Ignore G70, G71, G72” is not properly set. Please check the Prerequisites

Q: I have issues with the conductivity


Normally the setup can be run in Dry-Run mode. On some machines better results can be achieved:

  • when wirefeed is enabled
  • when water flows along the wire
  • when water is inside the tank

If this does not help:

  • check the resistance value of the mandrel relative to the machine table
  • check the resistance value of the rotation axis relative to the machine table
  • check any parts concerned like chuck, collet, …
