Safety Instructions
Building the printer will require a certain amount of physical dexterity, common sense
and a thorough understanding of what you are doing. We have provided this detailed
instruction to help you assemble it easily.
However ultimately we cannot be responsible for your health and safety whilst
building or operating the printer, with that in mind be sure you are confident with
what you are doing prior to commencing with building or buying. Read the entire
manual to enable you to make an informed decision.
Building and operating involves electricity, so all necessary precautions should be
taken and adhered to, the printer runs on 12V supplied by a certified power supply, so
you shouldn’t ever have to get involved with anything over 12V but bear in mind
there can still be high currents involved and even at 12V they shouldn’t be taken
lightly.
High temperatures are involved with 3D Printing, the Extrusion nozzle of the hot end
can run about 230°C, the heated bed runs 110°C and the molten plastic extruded will
initially be at around 200°C, so special care and attention should be made when
handling these parts of the printer during operation.
We wouldn’t recommend leaving your printer running unattended, or at least until you
are confident to do so. We cannot be held responsible for any loss, damage, threat,
hurt or other negligent result from either building or using the printer.

* Tips: Try to keep the thread rods parallel and the four wood pieces parallel. The
Y-axis must be a rectangle, that is the rods on both side should be parallel, so is the
front and back plate. Otherwise it will cause obstruction for the belt later. You can use
a Digital Caliper to measure.
