Hi gmarkusic,
there might be a couple of reasons for your observations (in order of likeliness):
- limit of distance between sensor and hot-bed exceeded => adjust bed screws by full turns, run tramming, then try leveling
- firmware corruption => re-install printer firmware
- CR-touch defective => connect USB host i.e. Pronterface & test CR-touch several times. In case of defective sensor replace it.
- mechanical problem on X-axis => turn printer off, move left extruder along the X-axis manually & remove dirt in case of mechanical resistance
- weak power supply unit => turn off nozzle & bed heating by setting 0°C temperature & run leveling. In case of success: Check PSU output voltage using a multimeter
Additionally, take a look here.
Good luck!
