I have my z endstops on all printers on a wheel, too, so I can simply perform a little twist to my endstop to lower or higher the entire bed, when needed. This of course does not affect the bed levelling itself. When a print does not stick I lower the node and when I see the nose is rubbing the filament down, I raise it again. That way I don´t have to use the wheels under the bed and don´t even have to mess with the z endstop settings in the printers firmware, as the process is done 100% mechanical.
