Ender 3 Pro CR Touch Z-axis offset? - eviltoast

I just installed the CR Touch kit on my Ender 3 Pro. Everything is wired up, but I can’t seem to get the Z-Axis offset correct. My process is:

  1. Auto-Home
  2. Step the Z-Axis down until there’s slight resistance on a sheet of paper between the nozzle and bed
  3. Take that value (Roughly -1.3) and put it into the Z-Axis Offset value
  4. Level bed

All of this works, but when the bed is leveling, the CR Touch needle is hitting the bed way earlier than the nozzle by maybe a few mm. When I go to print, there doesn’t seem to be adhesion in some places on the glass bed.

What am I doing wrong? :(

    In addition to what has already been said, personally I use auto-home and then move the hot end to the middle of the bed (On my printer, after auto-home it is the ABL sensor that is in the middle of the bed) and then set the Z position to 0mm.

    Then I go change the Z Offset setting until it touches the bed with the paper like you did.

    In theory I suppose the result should be the same but it might be worth a try if what has been already suggested by u/p1mrx is not your problem.
