CR-X Technical Notes
Z-Axis Sensor
The Z-Axis sensor is an externally mounted attachment to this printer, and must be
attached to the machine before turning the machine on. It is secured by two channel
nuts, which will turn and lock into place while tightening. The Z-axis sensor must be
mounted with the bottom of the sensor mounting in line with the base of the printer.

Levelling the bed
Like any printer, the bed must be levelled before use. This brings the nozzle to the
correct distance to the bed, and also accounts for any irregularities in the two z-axis
motors. Levelling the corners should be enough, but you can pre-heat the bed to get a
flat surface and level the centre as well. You should level so that you can feel slight
resistance when trying to remove a piece of paper, and the plastic should stick to the
bed without hassle.
Nozzle too far from bed
Nozzle too close to bed
Plastic not sticking (PLA)
Plastic not extruding
Plastic comes off mid print
Plastic has rough edges on first layer
Paper slides between bed and nozzle
easily
Takes force to move paper between
nozzle and bed.

gap between
the nozzle and

consistently)

CR-X Technical Notes
Loose/wobbly head
If the extruder head wobbles or can be shaken by hand on the X-axis railing, you must
tighten the tension nut to a point where it stops wobbling, then a slight turn after that.
The tension nut is located behind the bottom wheel, as part of the axle; this brings the
bottom wheel up closer towards the rail. Use the included spanner or a spanner from our
TH1910 set.
Nozzle assembly / thermocouple replacement
The front shield / fan-housing of the extruder can be easily removed by 2-3 screws on
the front of the extruder. Within, the nozzle is attached by a further 2 screws, which
mount it on to the base plate. From this point it should be easy to remove and replace
the nozzle, heater, or thermocouple when needed.

CR-X Technical Notes
Blockages should not occur at the nozzle and should be more prone to other areas;
which can be easily removed by disassembling the nozzle assembly. TH1766 would
help with this, as with TD2132.
Thermocouple errors usually show through abnormally high temperature readings while
the nozzle is still cold to touch. It is held in place by a small screw located on the side of
the nozzle.
