CR10 smart stops randomly during print

I’ve started to have issues with my creality CR10smart lately. It randomly stops during printing, sometimes at 10% sometimes 60% or any %. some prints may fail 3 times and suddenly the fourth it will print 100%.

The weird thing is that the printer stops at a point, keeps everything at that place and keeps bed and nozzle temperature at print temperature (creating a little blob where the print head stops). I read somewhere that it might be faulty connection, but all cables look perfectly fine.

Sidenote, the progress bar on the creality screen has stopped showing the print progress since a while, but did not have any impact on the prints.

Any idea how i can fix this?

Hello Sebastien, I have just recently purchased a 2nd hand CR-10 Smart, and face exactly the same issues as you. Any large print seems to fail. Firmware for both screen and motherboard is updated. Have you found a solution for the issue, and can pass on a hint?

Thanks in advance.
