After 3 cm heated bed for grid 2 plate keeps hitting the floor when pausing ( loosing position )

after installing a heated bed of 3 cm thick, now the plate keeps hitting the floor when pausing ( loosing position ) or cancelling. the reason is that it still calculates according to the original plate. how can i change the overall printing Z height ? thank you in advance.

from mprint location path in tools folder there is a slicer folder inside mprint slicer . modify the ‘end’ gcode for examle z110 instead of z115
