8.0 Supplementary Information
Flow Rate
This describes the rate of extrusion from the nozzle - normally
measured in mm³/s.
Footprint
This is the amount of flat area Robox® occupies when stood on
a surface - 370x340mm.
Gantry
This describes the assembly which includes the Z carriages,
X rails and X carriage. Its level is adjustable using two
independent Z drive screws.
GCode
The industry standard language for CNC control commands - it
has two distinct subsets - G and M codes, where G codes are
motion commands, and M codes are logic commands, such as
heater control.
HeadLock™
Refers to the printhead replacement system in Robox® - it
allows you to change the printhead quickly and easily.
HIPS
High Impact Polystyrene - a simple thermoplastic which is
frequently used as dissolvable support material as it bonds well
to ABS and can be dissolved in Limonene, leaving the ABS part
intact - see section 6.2.2.
Homing
As there is no direct feedback from the stepper motor in terms
of position, homing is how Robox® determines the location of
all axes before starting a print. Each axis moves until it reaches
its endstop, which is then defined as the origin. Because the
soware knows the length of each axis, soware limits can be
used at the other end of travel.
Hot End
This commonly refers to the heated nozzle section of the
extrusion system and includes the heater block and nozzles
inside the printhead.
Hygroscopic
This describes the tendency for some thermoplastics to absorb
moisture from the air - see section 4.3.
Infill
See fill.
Kapton® Tape
Kapton® is a trade name of polyimide, frequently used for high
temperature adhesive tapes and films. Many other printers use
Kapton® film as a bed surface, however in Robox®, PEI removes
the need for any coating on the bed.
Layer Height
This describes the height in mm of each individual layer of the
3D printed object. The thinner each layer is, the smoother the
appearance of the outside surface will be, reducing the ‘stair
stepping’ eect. Thinner layers = more layers = longer print.
