Z- axis sensor and leveling

Hey all,

First time I noticed something was wrong was starting a new print and the nozzle was just dragging the heat pad around.

I investigated, I changed the springs, tried leveling but everything was still too high. Come to find out my z axis sensor was loose and had been shifting downwards. Okay

I try setting the z-axis about close to where my bed is sitting with the springs not under pressure. Cool.

Then I try any other corner, they’re too high and I can’t level it down enough, it’s like corner 1 is too low. Holy hell I am driving myself insane! Also noticed the actual metal pad everything sits on is slated high on back, with a difference of 1/8".

So where am I supposed to have the z-axis sensor sitting? How do I fix this?

You need to set it up pretty much when you’re beef is level and tight (at least I did). This article explains it pretty well.

Side note - I upgraded to a bl touch and have never had to fuss with it ever again

Yeah I’m going to try again today to level it. I just get so frustrated then I have to set it aside before I want to yeet the whole thing off the balcony.

As for the bl touch, I’ve looked at it, but I am super wary of it because I have no experience with upgrading boards/software side of things. I am so scared I’m going to brick the whole damn thing.

Also not two minutes after my last post my printer decided it wanted to cooperate and become level. Nothing like technology to make you feel stupid.
