Bed Levelling fail when Light on

Hello, i have an X1C printer for 2 years now , and after the last update i have issues regarding the bed leveling when the built in led in printer is “on” , the pressure sensors of the heated bed fail.

I know that because every time i start a print with a light off then the print starts correctly.

Do we have any solution on that ?

Probably not, as you’re the first person I’ve heard reporting that issue. I’m running the latest beta and haven’t encountered it myself. Have you tried performing a factory reset on your printer?

Following a three-month period of troubleshooting, encompassing factory resets, bed alignments, and lubrication adjustments to the linear screws, a definitive solution remained elusive, particularly given the repeated suggestion of sensor replacement for the heated bed. A user on Reddit proposed an alternative approach involving the unscrew and screwing of three bolts surrounding the heated bed, as illustrated in the provided image.

Light actually was random event. The real issue was that sensors always had an external disturbance.
