  • straight knife measured to be bent with deviations up to 20 microns

  • cutting wheel quite possibly damaged

  • attempted cutting of module with silicon removed showed that the module is not immobile during cutting

  • movement in 10s of microns while cutting observed (could be solved with new/better knife and wheel)

ToDo: 1) repair knife and wheel 2) measure friction due to vacuum 3) check movement with deeper wheel bite and/or smaller cut angle
