This is a video showing some of the things we can accomplish with this machine:

2. Setting up the machine in Ultimaker Cura Slicer

In order to slice your own models, you should first set up the machine in the slicer. Follow these steps:

1. In the upper menu, go to Settings>Printer>Add Printer

2. Go to Add a non-networked printer>Custom>Custom FFF printer. Change the Printer name to Clay 40100

3. In the Printer tab, copy the settings as they are shown in the following image:

4. In the same screen, and in the Start G-code and End G-Code copy in each box the corresponding text below: 

START G-CODE

_{;Basic settings: Layer height: {layer_height} Walls: {wall_thickness} Fill: {fill_density}
G21 ;metric values
G90 ;absolute positioning
M107 ;start with the fan off
G28 ;move to endstops
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}
M117 Printing...}

END G-CODE

_{M104 S0 ;extruder heater off
M140 S0 ;heated bed heater off (if you have it)
G91 ;relative positioning
G1 E-1 F300 ;retract the filament a bit before lifting the nozzle, to release some of the pressure
G1 Z+0.5 E-5 X-20 Y-20 F{travel_speed} ;move Z up a bit and retract filament even more
G28 ;move to endstops
M84 ;steppers off}
G90 ;absolute positioning

5. In the Extruder 1 tab, copy the settings as they are shown in the following image:

6. Download the following print profiles to your computer: (Click on the links below)

7. In the upper menu, go to Settings>Printer>Manage Printers and select the tab Profiles.
