Relevant for
The Prusa CORE One INDX, CORE One/+, CORE One L, and the Original Prusa MK4/S, MK3.9/S are equipped with a loadcell, which detects whether the nozzle is close enough to the steel sheet for printing and prevents damage from the nozzle digging into the steel sheet.
The loadcell measures the amount of force that the nozzle applies to the steel sheet. In case the measured value is abnormally high, or undefined, the printer will show the message "Loadcell measured an infinite or undefined load value."
