Extruder head off-centre
The device no longer recognizes
the exact extruder position and
cannot build.
Return the extruder to the home
position to recalibrate the
BRESSER T-
REX 2. Abort your
object, empty the construction
platform, send the extruder to the
home position and restart your
object.
No PLA extrusion or adhesion to
the construction tape.
This may be due to the platform and
extruder head not being properly
aligned (levelled).
By levelling the platform, the
extruder head is aligned, which
improves the quality of the object.
Abort your object, empty the design
platform, level the extruder in the
home position, and restart your
object.
BRESSER T-REX 2 frozen
before object start.
BRESSER T-REX 2 may receive
contradictory commands.
Turn off the power switch, wait 30
seconds, and
turn on the power
switch.
Entanglements at the end of the
construction.
A layer of your object is not
adhering properly, the model was
secured to the construction
platform with minimal contact, or
the object was built floating and
without supports
above the
construction platform. Wrong Z-axis
offset, extruder tip is not aligned
with the correct distance to the
design platform.
Use the preview function of your
slicing software to display the
height and position of the first layer.
Build with supports
if necessary.
For information on calibrating the Z-
axis offset, contact Customer
Service.
No filament leaks.
Extruder clogged. Filament not
loaded properly.
Try changing the filament to make
sure the extruder gears have
gripped the filament properly.
Contact customer service.
Extruder not in home position.
Limit switch wiring
Contact customer service.
Straggly or frayed plastic layers
on steep overhangs.
Object overhangs are too far apart
or too steep (angle less than 45
degrees).
Building with supports.
