1. Plug the power supply into the 120 VAC wall outlet

   You should see a green indicator light on the power supply

2. Plug the other end of the power supply into the printer's power outlet and flip the switch to ON (| = ON, O = OFF)

   • The printer menu will light up and display: ULIO 3D BRIX Ready

3. End of this step

Troubleshooting if required

_{+ The green indicator light does not turn on}

Make sure the 120 VAC cable is securely connected to the wall outlet and the power supply

• Try another wall outlet
• It is unlikely, but maybe the power supply is blown, please contact us by email

_{+ The printer's LCD screen does not turn on}

• Make sure the power supply (24 VDC) is securely connected to the printer

• Make sure the printer power switch is flipped to the ON (|) position

_{+ Printer menu does not display ULIO 3D BRIX Ready}

• Please contact us by email

Make sure you have added a thin layer of lubricant wherever there is contact between the printer structure and the moving part of the hot nozzle (a tube of lubricant is included with the kit)

Initiate X-axis zeroing (Home X)

• Click the yellow button on the microcontroller → Motion → Home X → Click the yellow button again to initiate the command
• The X-axis rack should move to the right and make contact with the X-axis limit switch
• End of this step

Troubleshooting if required

_{+ The X-axis rack does not move at all}

• Make sure the X-axis connector is securely plugged into the X-motor
• It's unlikely, but it could be that the X-axis gear is slipping on the motor shaft
• It is unlikely, but it is possible that the X motor is defective, please contact us by email

_{+ The X-axis rack moves once and then stops moving}

• Zeroing initiation was not performed correctly
  • Redo the X axis zeroing

• Make sure the X-axis limit switch connector is securely plugged in
• It is unlikely but maybe the limit switch is faulty, please contact us by email

Make sure you have added a thin layer of lubricant wherever there is contact between the printer structure and the moving part of the print bed (a tube of lubricant is included with the kit)

Initiate Y-axis zeroing (Home Y)

• Click the yellow button on the microcontroller → Motion → Home Y → Click the yellow button again to initiate the command
• The Y-axis rack should move straight ahead and make contact with the Y limit switch
• End of this step

Troubleshooting if required

_{+ The Y-axis rack does not move at all}

• Make sure the Y-axis connector is securely plugged into the Y-motor
• It's unlikely, but it could be that the Y-axis gear is slipping on the motor shaft
• It is unlikely, but it is possible that the Y motor is defective, please contact us by email

_{+ The Y-axis rack moves once and then stops moving}

• Zeroing initiation was not performed correctly
  • Redo the Y axis zeroing
  • Make sure the Y-axis limit switch connector is plugged in
  • It is unlikely, but it could be that the limit switch is faulty, please contact us by email

_{+ The Y-axis rack moves with difficulty}

• Make sure you have added a thin layer of lubricant
• Make sure the bricks are laid correctly

_{+ The Y-axis rack is not heading in the right direction}

• Make sure you have installed the print bed in the correct orientation (refer to the manual).

_{+ The Y-axis rack is moving in the correct direction but cannot reach the Y limit switch}

• Disable the Y motor:
  • Click the yellow button on the microcontroller → Motion → Disable Steppers
• Try manually moving the Y-axis rack and check if it can reach the limit switch (you should hear a click) otherwise:
  • Contact us by email

_{+ The Y-axis rack reaches the limit switch but the Y motor continues to rotate}

• Make sure the Y-axis limit switch connector is securely plugged in
• It is unlikely, but it could be that the limit switch is faulty, please contact us by email

Initiate Z-axis zeroing (Home Z) Once the manual adjustment is complete, we can proceed to zero the Z axis (Home Z).

• Click the yellow button on the microcontroller → Motion → Home Z → Click the yellow button again to initiate the command
• The Z-axis rack should move upward and make contact with the Z limit switch
• End of this step

Troubleshooting if required

_{+ The Z-axis rack cannot reach the limit switch and you hear clicking noises}

• Click here to proceed to the troubleshooting section

_{+ The Z-axis rack does not move at all}

• Make sure the Z-axis connector is securely plugged into the Z-motor
• It's unlikely but maybe the Z axis gear is slipping on the motor shaft
• It is unlikely but maybe the Z motor is defective, please contact us by email

_{+ The Z-axis rack is not heading in the right direction}

• Make sure you have installed the Z-axis rack in the correct direction (refer to the manual)

_{+ The Z-axis rack moves once and then stops moving}

* Redo the Z axis zeroing

_{+ The Z-axis rack is moving in the correct direction but cannot reach the Z limit switch}

• Disable the Z motor:
  • Click the yellow button on the microcontroller → Motion → Disable Steppers
• Try manually moving the Z-axis rack and check if it can reach the limit switch (you should hear a click) otherwise:
  • Repeat adjusting the distance between the hot nozzle and the center of the print bed

_{+ The Z-axis rack reaches the limit switch but the Z motor continues to rotate}

• Make sure the Z-axis limit switch connector is securely plugged in

Preparation of PLA filament

• Cut the end of the filament at a 45-degree angle.
• Straighten the tip of the filament about 3 inches, pinch the handle of the extruder, and insert 1 inch of filament into the white Bowden tube.

Automatic filament loading

• Click the yellow button on the microcontroller → Change Filament → Load Filament → Preheat PLA → Click the yellow button again to initiate the command
• The hot nozzle should start heating up for PLA
• Wait until the temperature reaches 210 to 215°C
• When the buzzer sounds, click the yellow button to start loading the filament
• The extruder motor spins counterclockwise and pushes the filament through the white tube to the hotend
  • If the filament has difficulty passing through the gold fitting:
  • Cut the filament 45 degrees in the opposite direction, then try loading again (see previous steps)
  • You should see filament coming out of the tip of the hot nozzle, if not click purge more If you are unable to load the filament please contact us by email
• End of this step

IMPORTANT NOTICE:

NEVER touch the tip of the hotend with your fingers, as it is very hot!

Troubleshooting if required

_{+ The extruder does not turn at all}

• Make sure the hot nozzle temperature is at least 180°C
• Make sure the extruder connector is securely plugged into the motor
• It is unlikely, but it may be that the extruder motor is faulty, please contact us by email

_{+ The extruder does not rotate counterclockwise}

• This is unlikely, please contact us by email

_{+ The motor shaft turns but not the toothed gear}

• It's unlikely, but make sure the toothed gear adjustment screw is tight on the flat side of the motor else:
• Contact us by email

_{+ The filament comes out curling}

• You have an extrusion problem (probably a partially clogged nozzle) please contact us by email
