Getting Started

The machine settings for Cura are shown in the dialog below. These can be entered using the wizard or the machine settings dialog :


In addition the filament diameter should be set to 1.75mm on the Basic tab and the Nozzle Diameter set to 0.4mm on the Advanced Tab.

We recommend the following gcode for the start gcode :

G21        ;metric values
G90        ;absolute positioning
M82        ;set extruder to absolute mode
M107       ;start with the fan off
G28 X0 Y0  ;move X/Y to min endstops
G28 Z0     ;move Z to min endstops
G1 Z15.0 F{travel_speed} ;move the platform down 15mm
G92 E0                  ;zero the extruded length
G1 F200 E3              ;extrude 3mm of feed stock
G92 E0                  ;zero the extruded length again
G1 F{travel_speed}

and the following for the end gcode

M104 S0 ; turn off extruderM140 S0 ; turn off bed

G1 X-110 Y105 F7000 ;move X/Y to min/max

G1 Z160 ; move platform down

M84 ;steppers off

You can print your first object  within 15 minutes of receiving your new THREEDY. The THREEDY is sent out after it has been built, calibrated and tested. Each THREEDY comes with a spool of plastic pre-installed and print ready test objects on the SD card. The “Getting Started Guide” which comes with the THREEDY contains all you need to know to get started.

If the first layer of your print is not sticking to the surface or is not appearing correctly this may be because your platform is not level or your nozzle is the wrong distance from the platform.
Select the menu option “Prepare -> Auto Home -> Disable steppers.”  Carefully grip the nozzle unit and move it so that it is directly over the back left platform supporting screw. Take a standard piece of paper and slide it between the platform and the nozzle. Ideally the nozzle should very lightly grip the paper.  To ensure this is happening use the back left adjuster screw to move the platform up or down.  Then move the nozzle unit so that it is over the back right hand screw and repeat the adjustment operation using the back right adjuster screw. Move the nozzle unit so that it is over the front screw and repeat the operation with the front adjuster screw. If your platform was badly out of alignment you may need do repeat this three step cycle a couple of times.
Finally you may wish to check that the whole platform is leveled correctly by moving the nozzle unit to various points and testing with your piece of paper.

To change the filament the nozzle must be heated. Use the menu option “Control -> temperature -> nozzle”.  Set the temperature to “220C” or a value appropriate for your plastic type.

Lift the black rubber filament grip which is in the middle of the left hand side panel of the Threedy. Remove the white filament feeder tube from the hot end. To do this simultaneously press down on the small black disc and gently pull the white tube out. With a pair of scissors snip the end of the plastic filament (not the white tube!) to remove any melted parts. Pull the plastic filament back through the tube from the spool end and remove the old spool.

Put your new spool into your Threedy. Check that the end of your filament is cleanly cut and hread it through the filament guide tube which is underneath the extruder unit. Push the filament all the way through the white tube until 7cm is poking out from the end. Push the filament and the tube back into the black connector.  Push the black rubber filament grip back down to engage the filament drive wheel.
To test the plastic filament select the menu option “prepare -> move axis -> move 0.1mm ->extruder” and turn the dial to the right until the plastic comes out of the nozzle.  After a change of colour you may need to push through a small amount of plastic to ensure no residue of the previous colour remains.

Finally, turn the nozzle heater off by setting the temperature to zero degrees by using the method above ( “Control -> temperature -> nozzle”. Set the temperature to 220C) or by selecting the menu option “prepare -> cool down”.

Each spool has 1 kg of plastic. NB this does NOT include the weight of the spool itself, which is an additional 230 g (this is useful information when you want to calculate how much plastic you have remaining on a part-used spool).

If you don’t fancy designing your own prints, there are loads of 3D printable files available on the world wide web that you can download to print on your own 3D printer.

Some offer professionally designed models, others are creations shared by other users. Many are free, some also offer premium 3D print files.

Whilst this list is in no way complete, here are links to some websites you may like to try.

Explore, find something that takes your fancy, have fun with your THREEDY 3D printer!

We love to see what you’ve been printing with your THREEDY – please do keep in touch and send us photographs of your creations!
