Introduction:
The Creality K1 Series all (as of feburary 2025) use four strain gauges under each corner of the hotbed to determine when the nozzle is contacting while homing and z-levelling. The levelling PCB Adapter Board under the hotbed and the strain gauges themselves can sometimes be defective requiring replacement. You will know if the nozzle continues pushing through the buildplate causing damage while homing/levelling.
