Z axis slams into bed/bltouch offset?/autohome, start print slams

Ok so i think its my bltouch offset it was 1.9 before frimware upgrade now it gose to 13.9 on z axis. But my printer offsets are 1.9 and dont go higher then 10? Also in frimware it thinks its at 1.9 but its at 13.9? How and where would i change this? What do i do? Im not great at all this kinda new? It slams my z axis into bed after auto home and bl-touch leveling if i start print. I think its going down an extra 12!! I have took my z axis aprt 5 times now after binding when it slams! Thank you i hope someone else has had this and fixed it. Thank you for the time.

Do you have ABL_BILINEAR_SUBDIVISION enabled?

Could it be this : [github.com]

Well after reading that like it kinda seems like that. since new frimware it hits max bedleveling spots now it seems. But dont see how to try to fix or turn off? Thank you very much for your reply. Any thought on turning off

The BL-Touch Z_PROBE_OFFSET_FROM_EXTRUDER can't be 13.9 mm. The BL-Touch pin only moves a few milli-meters so it needs to be just a little bit less than 0.0mm depending on how you have it mounted.

You should turn of all bed leveling until you can get the printer to home correctly and print a small object in the center of the bed.

Okay thank you I will try now

Thank you how do i turn off the ved leveling? Thanks again i rally appreciate it

In your configuration.h file, there will be a section that looks like this:

//#define AUTO_BED_LEVELING_3POINT
//#define AUTO_BED_LEVELING_LINEAR
//#define AUTO_BED_LEVELING_BILINEAR
//#define AUTO_BED_LEVELING_UBL
//#define MESH_BED_LEVELING

Make sure all forms of Auto Bed Leveling (including MESH_BED_LEVELING) have the two // in front of them.

Okay thank you I really appreciate that I'm going to try that now put two slashes in front of all bed leveling thanks again hope this works
