I am having the same problem. I can't seem to get the bed leveled and when the bed moves vertically, it sounds as though it is making a screeching sound.
If you are having issues with getting it leveled, I would watch Creality's guide on this at
I tried this and it didn't work. The bed is about 3 inches from the nozzle. This is after I change the settings when printing as instructed then rehomed. I have been playing with this thing for almost 2 weeks and need to know is this prints or not by tomorrow as that is the last day to return it.
If their official support video does not work, you can try contacting Creality directly for further assistance with possible issues: https://www.creality.com/service-request
I have tried that. Their response has been very lacking. Not very helpful.
If it still not working after reaching out to them and following their help videos, it may be best to bring this back in to your local Micro Center store for further assistance.
