The following description shows calibration universally for the maker construction kit and the preassembled device. Subchapters
"15. b) Setting of the Z-Stop" and "15. d) Setting of the Printing Plate" apply to both models.
 Whethertosettheprintingplateinthehotorcoldconditiondependsonwhetheryouhaveappliedanadhesivelmtotheprinting
plate or not. By default, this is included in the delivery only for the construction kit.
 Itisasimplerulethatcalibrationisperformedinthecoldconditionwiththelmandinthehotconditionwithout.Thisisbecausethe

Calibration should be performed now and then. It is a prerequisite for high printing quality. Always perform calibration after transport
of the 3D-printer or after any changes to the printing plate.
 Thepreassembleddevicewascalibratedinproductionalready.Beforeyouprintforthersttime,checkthedistancebetweenthe
nozzle and the printing plate in the hot condition in any case.
