Heated bed cable damage
The cable that connect the heated bed to the board rubs the steeper motor case damaging it. This is not something that normally wouldn't be a problem but if the bed is used to it maximum, moving back and forward the hot bed, then the steeper motor case keep taking aways bites of the cable cover making it extremely dangerous.
Could you please indicate where I can get a replacement for the cable? There is not supplier for that cable online, neither on the creality shop.
Also as product improvement you should check how either sercure the cable so this does not happen or cover the case avoiding any sharp ends
