Cetus mk3 autobed level error

Hi im having trouble autoleveling my cetus mk3
I select Auto level from the Calibration menu, it asks me to " Please touch the switch" which i do then it moves to the first point on the bed then freezes, the printer then seems to disconnect from the pc and an error " Error: failed to get printer idle state (ctrl) (3100.3100.3100.3100.3125) " i have tryed power cycling both pc and printer and reinstalling software yet still the same.
