Inconsistent bed levelling

I am new to 3D printing.  I purchased an Ender 5 Pro and have not been able to get a first layer yet.  I've tried dozens of times to level the bed.  The first layer would either not come out at all because the bed was too close or it wouldn't stick because I could see the nozzle was too far from the bed.

I've come to realize that bed levelling is not consistent.  I can level the bed so that a piece of paper is barely being scratched by the nozzle.  I then move the Z-axis down by 10mm or more.  Then autohome and every time the nozzle is either pushing right up against the print surface so that I can hear the nozzle scraping the build surface after disabling the motors.  Or I can easily slide a piece of paper under it and see a lot of daylight between.

I've repeated this process of levelling the bed, moving the bed down, autohome, level again over 5 times now without even trying to print. Every time the bed level was off by a lot.  Is this normal?

@czeeb I must admit, I don't have that problem. My previous problem was me telling it too high until I notice that the nozzle is clogged up prom a previous print. I have to make sure I clean the nozzle after each print.

Now once I have levelled it, its ok. The other thing is I make my first layer to be 0.3mm just in case I levelled the bed too close so that it doesn't scratch the bed.

@derby_don I guess he solved this problem.  Bed leveling is a compulsory course for 3D printers. If you have any problems with this.

Hi all, I have the same problem. When I level corners and they are spot on, the centre of bed is too high it look like is bowed in the centre. It is brand new. Any idea??

Hi, same issue here, autohome, level the bed, then autohome, then level again (x3), everytime the z axis is always 4 or 5mm off ? 

edit : I made a video :

edit 2 : found the issue :

tl;dr : order new endstop switches

Mine isn't as bad as 4mm but levelling is a major issue, but also random. Sometimes can level and it stays fine other times just moving plate down then auto home and it's wrong. Sometimes auto home is ok, then the print is out.

 

Sometimes end up tweaking the levelling as the skirt of my print is going so that actually level for main print

 

Driving me mad! Bit confused as to if bltouch upgrade would help as install video still shows manual levelling. Is it just more accurate than the microswitch? Any point trying to adjust the z nut at the back ?
