A small update to the topic.
On the left, Benchy cut and sent to print on CrealityPrint v6.1 and on the right, the same project cut and sent to print on CrealityPrint v5.1.7.
When this broken print on the left ended, the hotbed moved forward rapidly until you could hear the y-axis belt jumping on the stepper motor gear, and after clicking OK, the printer screen displayed the message CM2789 Abnormal resistance in the y-axis movement direction motor released. Fix issue and restart.
In the case of print cut and send on CrealityPrint v5.1.7 , the one on the right side of the photo, there was no such strange behavior.
Also, the same project cut and sent to print by OrcaSlicer v2.3.0 ends with failure.
Default models for printing placed by Creality on the machine come out perfectly, after downloading the gcode of these prints I read in the header that they were cut in CrealityPrint v5.1.7
I contacted Creality online consultant, he sent several links to their wiki, which indicated a poorly closed camera shutter, loose screws and added that they were very sorry for the problems and that’s all they can advise at the moment
When the printer is turned off mechanically everything moves smoothly.
When turned on manually forcing the head movement you can also easily go around the entire hotbed.
Does anyone have any idea how to solve this problem?
