4 Test Printing
Please test nozzles before your first printing, which is required for first printing only.
4.1 Using the ReplicatorG Control Panel
1)
Click the button as shown right to open the control panel.
The control panel pops up.
Press these buttons
only when temperature
reaches 220°c
Use arrows to “Jog”
the machine
around.
X = Left-Right
Y = Front-Back
Z = Up-Down
REVERSE : unloads filament
FORWARD : loads filament
Tells you the current
Temperature of your left
and right extruders.
Single extruder cubes
will appear as
“right” extruders
When testing make sure the nozzle is well above the
build plate. You can “disable” stepper motors in an
emergency to stop the head crashing into the bed
2)
Type in target temperature
Usually :230°c for PLA
210°c for ABS
Once the nozzle is at temperature (220° C), load filament as shown below.
Click “Forward” button, and then take the filament and push it. You'll have to use
some force. After a few moments you should feel the motor pulling it in. Then let go.
You’ll see some plastic start to come out the nozzle.
When that happens you may hear the noise like “tah-tah-tah” . Please maintain
pressure on the filament for 25 seconds. Then the noise will disappear. It also works
when changing material.
18
Mbot Manual ~ Cube (PLY or PVC, Single or Dual)
3)
If the noise doesn’t disappear:
Click the “Backward” button on the control panel, to pull the filament out. Cut off the
used segment. Input “230” as target temperature and press “Enter” on keyboard.
When current temperature rises to 230° C, click the “Forward” button. Then take the
filament and push it with some force until some plastic comes out the nozzle.
If it still will not load please remove front fan and check that there is nothing blocking the filament path and try again.
NOTE fans go on with the voltage info at the back of the fan not facing forward.
Close the control panel if the machine works well.
If plastic stop coming out the nozzle or the noise reappear during printing, please stop printing and
rotate z-axis manually to keep the nozzle from the build bed. Then take the measures described
above .

5.4 Other Important Printing Information
1. Spool placement
When assembling the spool
holder bracket (i.e. our printing
example since chapter 3) to
hold material, please push in
the direction as the red arrow
points, in order to get the
maximum space.
The blue filament pictured
right has been loaded so that
the filament loads clockwise
and consequently can drop
back off the spool and across
the spool holder. It will then
get stuck between the black
spool and the back of the machine, or even get jammed
between the spool holder and
spool!
The red filament shows the
correct placement of the
spool, with the filament being draw up from the bottom of the spool straight up to the filament feeder tube. The blue spool should be turned around to mirror the red.

2. The Printer Bed
The composite printer bed supplied as standard with the Cube is a
thick layer of fibreglass with a top layer of special material that
makes your print stick whether in ABS, PLA or other material.
Other 3D printers use a heated bed so that ABS prints sticks when
it is hot, but releases when cool.
BilbyCNC have found the printout sticks to the bed better than
using a heated bed—but the downside is that releasing the
printout can be difficult.
Printer Bed Close-up
BilbyCNC consider the printer bed to be a wearing part and damage to it’s surface is not
covered under warranty. We suggest the following tips to help you get the maximum life out of
your bed.
PRINTING WITH PLA—BLUE TAPE
If you are printing with PLA, blue painters masking tape still seems
best at having your print stick during printing, but easily removed
when complete.
Apply strips of the tape over your printing area evenly and smoothly.
You may find you need to adjust the bed level after applying to allow
for the thickness of the tape.
When the tape gets “worn” or damaged. Simply remove the tape and
apply new tape.
PRINTING WITH ABS—ABS SLURRY
Acetone is flammable and not good for you—please read the safety precautions on the bottle.
ABS can stick so well to the bed that the bed is damaged when removing your print—this is
especially true for prints with a large “footprint” - where the area of plastic directly in contact
with the bed is large. We strongly suggest making an ABS “slurry” to apply to your bed.
To make the slurry, put some scrap ABS filament in Acetone in a safe container such as a
glass jar (acetone will dissolve many plastics). It is freely available, try your local hardware
store.
The filament will dissolve over a few hours to form a liquid. Acetone is normally very runny—
like water. The resulting liquid can be very thick, but you want to keep it runny. It will dry almost
instantly, so you want to err on the runny side, any excess will evaporate. Just add more acetone if required.
Use some folded paper towel to dip in the slurry and wipe across the bed, getting it as smooth
and even as possible. It will dry almost instantly.
26
Mbot Manual ~ Cube (PLY or PVC, Single or Dual)
The layer you’ve just created will stick very well to the bed, and your print will stick well to it. In
some ways it creates a sacrificial layer between the bed and printout. It will be the weakest
point if you need to use a spatula to remove the print, so neither the bed or your printout are
damaged. Simply reapply the slurry when it gets damaged or scraped off. You can remove the
layer with paper towel and acetone if you require.
3. Temperatures and Feed Rates
INTRODUCTION
The MBot Cube and Cube 2 are based on the open source Makerbot designs and software for the Replicator 1.
It works well with a special version of the ReplicatorG software, which takes into account the different size, offsets and
setup of the Cube.
Please read our accompanying sheet on preparing the printer bed before printing.
PRINTING SPEEDS
The Cube is not the fastest of printers, but it has the advantage that you can experiment with the setting in the ReplicatorG software. We have found the following settings advantageous when used with the standard, BilbyCNC or nylon
type filaments

6 Two-Colour (Dual) Printing
To print a model with two colors, you’ll first have to have both parts saved as separate .stl files.
Then generate GCode by ReplicatorG for each model to generate one x3g print file.
Step—By—Step example : Earth
The picutre below shows the model after slicing.
1) Click the “File” menu and choose the file for Part 1.
2)
Then go to “GCode” -> “Merge .stl fir DualExtrustion)
The pop-up window shows as below.
Click here and select the model file
for the left extruder to print
Click here and select the model file
for the right extruder to print
Click here and select the
directory to save the GCode
28
Mbot Manual ~ Cube (PLY or PVC, Single or Dual)
3)
Click the “Merge” button and you’ll see three pop-up windows as shown below.
In the EARTH example : on the two setting windows, uncheck the “use raft/support” option and
select “None” in the “Support Material” list; because two models can support each other.
You can now enter all your desired settings for Layer height, Shells etc.
We suggest :
Layer Height : 0.27
Shells: 3
Fill : 10%
Temperature : 210
Feedrate : 41
Travel Speed : 60
Then click “Generate GCode” on both windows
For further Technical Support visit www.bilbycnc.com.au
29
You will then get 2 pop up progress windows as ReplicatorG slices both files
It can take up to 30 minutes to slice the Earth example file.
When finished it will look like this :
