Disable software endstops (M211 S0), preheat and with motion z to grab paper: get deltaz (positive or negative, for example 0.3)

• configuration → runout sensors → off
• temperature → preheat PLA → preheat PLA
• motion → z

adjust probe z-offest adding deltaz:

• configuration → probe z-offest → =z-offest+deltaz

enable software endstops (M211 S1)
