In September, I bought an Ender 3 v3 Core XZ printer and I like its speed and precision. But for the past month, randomly and for no reason, when starting a print job, in the last phase of the initial adjustment, when after cleaning the nozzle it returns to the center, in one of the downward movements it does not touch the bed and then rises halfway and gives the error CL2529. There is no obstacle preventing it from descending.
If I press to restart the print, it adjusts correctly and prints without any problems.
I have been searching forums and have not found a solution. I would appreciate it if anyone could give me some ideas on how to fix this.
Thank you.
