Bl touch z offset

HudsonCap

I cant get my Bl touch z offset right. I have an ender 3 pro and iv fallowed many guides none of them have fixed my problem. first when it looks right the front of the print is fine but the back is to lose any help would be helpful. i am new to 3d printing so if im doing something wrong its probably because of that.

Hi,

What are you using the probe for?

if its fine at the front but not at the back then the issue is with your bed levelling not the offset.
This is the macro I use for levelling my bed on my ender 3

Run this and it will tell you how much each corner needs adjusting.
