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:
- Auto-Home
- Step the Z-Axis down until there’s slight resistance on a sheet of paper between the nozzle and bed
- Take that value (Roughly -1.3) and put it into the Z-Axis Offset value
- 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.
Wait, sorry. What’s supposed to touch the bed? The hot end or the ABL sensor?
