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
