corner ringing
This is a type of pr int defect characterized by a ripple pat-
tern which quickly dampens and is seen on the vertical faces
of prints, particularly after a direction change in the sur-
face.
cylindrical coordinates
Cylindrical coordin at es are one way of extending polar co-
ordinates to three-dimensional space: cylindrical coordi-
nates use the r and ✓ of polar coordinates, plus a z height.

DHCP
DHCP (Dy n am i c Host Configuration Protocol) is a cli ent/server
protocol that automatically provides an IP host (such as
your 3D printer) with its IP address and other related net-
working parameters such as the IP subnet mask and de-
fault gateway I P address. In the absence of a DHCP server
on a local network, each network device (such as your 3D
printer) will need to have a statically (i.e.,manually)as-
signed IP address.
extruder
The extruder, or extruder nozzle, of a 3D printer is the
nozzle at the bottom of the print head, that is extruding
the melted filament. 144, 145, 176, 220, 225, 232, 233, 235,
