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.
(Left: You
should be able
to see a small
gap between
the nozzle and
the bed, the
plastic should
lay out
consistently)
