_{+ 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

_{+ 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 plugged in
  • It is unlikely but maybe the limit switch is faulty, please contact us by email

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

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

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

• Contact us by email

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

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

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

• 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

_{+ 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

_{+ 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
• It is unlikely but maybe the limit switch is faulty, please contact us by email

_{+ 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
