Frequently Asked Questions

screws or knobs that control the position of the bed. If your printer
has an adjustable bed and you’re having trouble getting your first
layer to stick to the bed, the first thing you will want to verify is
that your printer’s bed is flat and level. If the bed is not level, one
side of your bed may be too close to the nozzle, while the other
side is too far away. Achieving a perfect first layer requires a level
print bed. Cura already includes a useful bed leveling wizard that
guides you through the bed leveling process. You can find this
wizard by going to Tools > Bed Leveling Wizard, and following
the on-screen instructions.
(2) Nozzle starts too far away from the bed
Once your bed has been properly leveled, you still need to
make sure that the nozzle is starting at the correct height relative to
the build platform. Your goal is to locate your nozzle the perfect
distance away from the build plate-not too far and not too close.
For good adhesion to the build plate, you want your filament to be
slightly squished against the build plate. While you can adjust
these settings by modifying the hardware, it is typically much
easier (and much more precise!) to make these changes from Cura.
To do this, click “Edit Process Settings” to open your process
settings and then go to the G-Code tab. You can use the Z-Axis
global G-Code Offset to make very fine adjustments to your
nozzle position. For example, if you enter-0.05mm for the Z-axis
G-Code offset, the nozzle will begin printing 0.05mm closer to
your build platform. Be careful to only make small adjustments to
this setting. Each layer of your part is usually only around 0.2mm
thick, so a small adjustment goes a long way!
