Hello,
I’m having a problem with the calibration of my 3D printer. When I start a print, regardless of the software (Creality Print, Orcaslicer, or Cura), the printer starts calibrating the bed. So far, no errors have been detected, except that the printer won’t print and instead starts calibrating non-stop in a loop. It calibrates for hours. I can only manually turn off the machine, otherwise the calibration will never stop. I tried disabling it, but the printer still starts calibrating. I tried restoring the machine to factory settings, but during calibration, it starts calibrating again in a loop. The day before yesterday, I had no problems; the printer printed fine, but since yesterday, I’ve been unable to start a print without being stuck on a continuous calibration of the bed. Has anyone else had this problem, and if so, what’s the solution? I had thought about using the “Co Print KCM Set” kit to switch to color because apparently you have to change the entire operating system and I think that this could solve the problem but is that really where it comes from? Mysteries
I’ll check if there are any damaged components and if everything is connected correctly just in case.
I made a video that explains my problem even better, but I also realized that the calibration is done randomly on the points of the platters
Havent updated the software by any chance?
No, but if I turn the printer off and then turn it back on, it starts again. It’s stuck on calibration. But I don’t understand, Creality has two different guarantees on their machines? The warranty they sent me in a photo by email explains that the components are guaranteed for 3 months max but on the store’s website it is guaranteed for 12 months. Do you know how long the warranty could be?
I found a solution, from Orca, I can control the printer, I deleted the part in the gcode that requires calibration before each print. I can normally print again. I will have to try one day to launch the calibration, but as long as it works without, it’s good. 
After a few attempts, nothing works and I can no longer print at all. The printer is stuck on this calibration. Everything is connected correctly and no components are burned out. I will see what to do but I think I will change printers, I think that is the best solution
Bummer, you’d think creality would have its act together by now.
I had a lot of repairs at my expense, almost half the price of the printer. For me, the problem is more complex than expected. The sensors react well with the printer, but the nozzle is too far from the bed, you can easily pass a finger between the nozzle and the bed. What surprises me is that Orca manages to generate the bed mesh but the printer remains stuck in its calibration. I managed to get different errors by letting it run for two hours.
The calibration is very strange over two hours. First it tests the four points as usual then each point of the board, i.e. the 36 points. Then it comes back to the middle and as in the video will be blocked between the middle and the back of the board. After a while it will test the four points again and take the center of the board as a starting point. It tests the center then goes to the first point of the board, comes back to the center then goes back to the second. Then it redoes the four points before testing the board in all directions and especially diagonally. It redoes the four points after and starts again point by point.
the first error is generated after the first calibration before entering the endless loop:
Abnormal auto-leveling! Please check according to the instructions.
By clicking on report, a report is sent to creality and I am asked to contact them
then the second one comes:
Error code 3000 Unknown exception
then the third:
Error code 2342 Unknown exception
then the fourth: Abnormal mainboard fan! please check according to the instruction
and the last one: CL2533: The level sensor may be subject to external interference
According to the Creality wiki, only the last code is known. This code will be displayed almost two hours after the calibration is launched, but the printer will continue its loop.
For me the problem comes from the motherboard and more precisely from the heat. A fan placed on the side with little space and almost no other opening towards the motherboard is not enough. I really dread the summer, I will have to think about modifying this if I do not want all the other components to end up burning out
After receiving the 4 sensors and the electronic card, still the same problem but Creality sent me a video “Service Tutorial Ender-3 V3 Plus Layer line adjustment” which I followed to the letter and everything works correctly again
