Can someone help me? I have an Ender 3 V3 and broke the ribbon that attaches to the touchscreen. I am in the process of getting a replacement, but I need to do something about my z offset. It doesn’t seem to be taking when I change it through the software. Every time I print, it is smashed down, and I end up canceling the print. I can’t find any help on manually leveling the print bed, adjusting the limit switch, or precise ways to set z offset through the app or software and for it to stick.
As far as I know, the ribbons are broken and the software can’t send any commands to the firmware, you need to find an aftermarket to fix the ribbons
Hello @Christy_Timms …! 
Welcome to the Creality Forum…! 
Glad you could make it over here… 
I’m not sure which Ender-3 V3 you have but to look for instructions on leveling you could try this

. Pick out your printer and see if there is something in the menu to help you. Also a You Tube search might help. Sorry I don’t have that model so i can’t be much help.
