7. Secure the filament guide tube to the 
back of the printer using the two clips. 
Ensure that the guide tube can reach the 
extruder, but do not connect it to the 
extruder yet. 
8. Remove the outer plastic nut from the 
filament support bracket, then insert the 
threaded end through the hole in the 
back of the printer. Screw the nut onto 
bracket and tighten it from both sides. 
Take care not to over-tighten. 
9. Ensure that the power switch is in the 
OFF position (with the Oside depressed). 
Insert the C13 plug on the included AC 
power cord into the C14 panel connector, 
then plug the other end into a nearby AC 
power outlet. Depress the Iside of the 
power switch to turn the printer ON. 
11. Press the center button on the control 
pad to activate the menu system. Select 
the Info & Settings -> Preheat Settings -> 
Extruder entries. Use the Up and Down 
buttons to change the target temperature 
to 215°C, then press the middle button to 
set it. Press the Left button twice to 
return to the main screen, then select 
Preheat -> Start Preheating. 
 
 
 
 
 
 
 
 
 
 
12. Once the target temperatures have 
been reached, place the spool of PLA 
filament onto the filament bracket. Insert 
the filament into the bottom of the 
filament guide tube and continue pushing 
until it emerges from the other end. 
10. Squeeze each corner of the build 
platform and tighten the wingnuts to 
minimize the platform height. Press the 
middle button on the control pad to 
activate the menu system. Use the Up and 
Down button to move the pointer to the 
Utilities entry, then press the middle 
button to select it. Cursor down to select 
the Level Build Plate entry. Follow the on-
screen instruction while adjusting the 
wing nuts to raise the plate to the point 
where you can just slide a single sheet of 
paper between the build platform and the 
nozzle at all points on the platform. 
13. Press the center button to open the 
menu system, then select Utilities -> 
Change Filament -> Load. Feed the 
filament into the opening in the top of 
the extruder. Once filament starts 
extruding out of the nozzle, press the 
center button to stop the load process. 
Without removing the filament, insert the 
top end of the filament guide tube into 
the larger hole in the top of the extruder 
surrounding the inserted filament. 
 
14. Insert the SD card into the vertical slot 
on the right side of the printer. Open the 
menu system and select Build from SD. 
Choose one of the sample 3D models, 
either 42mmboxright.X3G or Test 
right.X3G, and press the center button to 
begin printing the sample. Please note 
that the single extruder is referred to as 
the Right Extruder when slicing models.
