Removing The Filament From The Extruder; Printing Objects From The Usb Flash Drive - CraftUnique CraftBot User Manual

4. Move the extruder switch on the top of the extruder to the left into the "unlocked" position. This will
allow the filament to bypass the gears. Push the filament into the extruder hole as far as it will go.
5. On the LCD screen main menu select either the extruder or the thermometer icon from the extruder
menu, press the thermometer button. At this point you will see a new menu indicating the "Head
temp" and "Bed temp". You can select the extruder icon and the bed icon (line with 3 wavy lines
above) to commence heating. One the extruder is fully heated, you may start the printing process.
6. When you see the filament begin to extrude, return the extruder switch to the right, into the "locked"
position.
7. You can also use the "extrude" menu in the touchscreen to push for filament out of the nozzle.
8. Re-insert the filament guide tube back into the hole at the top of the extruder.

6. REMOVING THE FILAMENT FROM THE EXTRUDER

Never remove the filament from the extruder if the extruder is cold! Always preheat the extruder before
removing or changing filaments. Removing the filament from a cold extruder might damage it! You
don't have to remove the filament between prints.
1. Heat up the extruder (see section 10.5.)
2. Once the extruder reaches the target temperature of your filament (keeping in mind that different
materials such PLA, ABS, and PET have different temperature characteristics), press the "extrude"
button briefly, and then touch the "reverse" button and hold a short while. Once the gears have
begun to retract the filament you will be free to pull it out from the printer and then load a new
filament.

7. PRINTING OBJECTS FROM THE USB FLASH DRIVE

1. Save the printing command file created by CraftWare slicer program on a USB flash drive. The pen
drive provided with CraftBot has design samples saved on it. (3D designs must be converted into
a printing command file with the help of the CraftWare slicer software. For details on this go to
chapter „Using CraftWare" or to www.craftunique.com/craftware)
2. Insert the USB drive into the USB slot located on the top front of the appliance (above the LCD screen).
3. Select the USB Print option from the main menu.
4. Scroll down with the arrow to select the object's file name.
5. Push the printer icon in the left corner.
6. The appliance will heat up the extruder and the build plate to the desired heat.
7. Printing will start if the required operational temperature is reached – until then you will see the
current heat along with the status message: „Now printing „file name". Heating"
8. During printing the status of the print is displayed on the LCD screen, indicating progress, based
upon a percentage of the job completed.
