Primeline scrapes the bed

New v-core 3.1 default 400 with EBB42v1.2 & SKRAT, all looks well but primeline scrapes the bed (EMERGENCY STOP) this is after homing and mesh completes successfully. I set my Z offset using the paper method. Attaaching printer.cfg

Do you still have the klipper log from when it happened?

I dont, guess i was running Z-probe wrong, did PROBE_CALIBRATE and its "starting" to work, prints are sliding off at layer 2, adjusting and testing

You said earlier you did it via the paper test. Was that not with probe calibrate? https://www.klipper3d.org/Bed_Level.html#the-paper-test

it was not with probe-calibrate, just used mainsail then z offset>>save, I think i dindnt try to "get z=0" just did a save config when i hit the paper, also removed the gcode offset from the filament gcode (z=0 was the default) seems to be working, curious why probe_calibrate isnt the default instruction?

What instruction are you referring to? But yeah, probe offset is from z=0. If you don't start from there you will get incorrect results like you experienced
