So I'm at my limit with my ender 3 and could really use some help.. I have installed a bltouch and have no end of issues since and cant figure out wtf is wrong.

Physical install went fine, it was an official creality kit and I flashed it and took away the z end stop as per instructions.. I had no luck with original flash as the probe wouldn't allow the end to get close enough to the bed so I found an updated firmware and managed to get that to work. I have also just installed yellow springs and octoprint. Issue now is when I try to level the bed it all goes to bog. I use a chep bed levelling gcode, I get the paper to just be under the end and think it's fine, then I try a test print and the end is suddenly not low enough and I just end up with this horrific blob being dragged around the bed....

Can someone tell me what I'm. Doing wrong?
