Each time you attach a new Smart Extruder+, you will need to run the Z-Axis Homing Calibration routine.
This process will make sure the build plate is positioned at the correct distance from the Smart Extruder+
when you begin a print. Before attempting to run Z-axis homing, allow the Smart Extruder+ to cool. Once
cooled, unload any filament and clear any debris from the extruder nozzle and build plate. Navigate to
Settings > Calibration > Calibrate Z-Axis Oset on the Control Panel to begin Z-axis homing calibration.
The MakerBot Replicator+ will then check and record the location of the build plate.
Before beginning the leveling process, please consult MakerBot Support at https://support.makerbot.com.
The build plate is the base on which your prints will form and is leveled at the MakerBot factory, but over
time it might shi slightly. If you’re having trouble with print adhesion, you may need to level the plate
again.
Navigate to Settings > Calibration > Level Build Plate > Start Assisted Leveling on the Control Panel to
begin leveling the build plate. If filament is loaded, you will be prompted to unload filament.
Before attempting to level your build plate, allow the Smart Extruder+ to cool and clear any debris from the
extruder nozzle and build plate.
When directed with the control panel, using the 4 mm hex key included in the setup kit, first tighten the
front le and right screws 2-3 full turns. Select Continue with the dial.
Next, turn the leveling screws slowly until a light appears on the extruder. Press the control panel dial to
move to the next step of the leveling process. The extruder will move to dierent points around the build
plate to make sure the plate is at the appropriate distance from the Smart Extruder+ nozzle. Turn the
leveling screws according to the instructions that appear on the control panel screen. Instructions on the
MakerBot Replicator+ control panel will also guide you through this process.
The surface of the MakerBot Replicator+ build plate, known as the Grip Surface, allows for better print
adhesion and quality than using a surface like blue tape. However, over time, the grip surface can become
cracked and damaged. If these cracks or tears begin to aect print quality, it is time to replace the grip
surface.
