Replacing a Head

When a head reaches the 1500 build hour odometer limit (800 hours for a TPU 92A head or
700 hours for an ABS-CF10 head), a warning will be displayed on the User Interface and the
head's Head Status Icon will be highlighted in red on the Materials page. You can continue
using a head which has exceeded its odometer limit, but it is highly recommended that you
change the head as part quality will be unpredictable. See
instructions on replacing a head. Replacing an ABS-CF10 head is the same as replacing a
standard head.
The process for replacing a PLA head varies slightly from the process for replacing a standard
head. When building with PLA material a specialized PLA head is used. The PLA head must be
installed into the model head location within the gantry. A cooling module is used in conjunction
with the PLA model head and must be installed into the support head location within the gantry.
The PLA model head extrudes both model and support materials. See
