Remember to apply lacquer, Fixpad or tape to the bed to increase the adhesion of the
filament. Otherwise, the pieces will not adhere correctly.
The piece is being printed OK but the edges have started to come unstuck
This is also due to incorrect levelling. If the distance between the extruder nozzle and the
bed is too large, the filament at the ends of the piece will not adhere properly and will
come away. Make sure that auto-levelling is enabled, or alternatively, you can level the bed
manually again. Remember to apply lacquer to the base to increase the adhesion.
Can I pause a print job?
You can pause a print job by pressing the control wheel and selecting the Pause icon. When
you are ready to resume printing, press the Resume icon.
Can I stop a print job?
You can stop a print job in progress by pressing the control wheel and selecting the Stop
option. You can also use the kill switch by pressing and holding the control wheel. In that
case, the print job will not be resumed.
The extruder is blocked
Heat the extruder to 220 °C and push a needle through the nozzle to clear it. If it is
still blocked, follow the instructions provided on this page diwo.bq.com/en/product/

Can I add a heated bed to my printer?
You can add a standard RepRap heated bed, but you will need to switch to a higher power
supply unit. BQ accepts no liability for any resulting damage to the printer or injuries
suffered by the user.
The filament is being expelled from the extruder instead of going in
You might have connected the motors to the board the wrong way round, causing the
polarity to be inverted. Disconnect the motor and then reconnect it in the correct position.
Before you do this, make sure that the power supply to the board is disconnected.
The printer will slow down if the control wheel is moved briskly during printing
Handle the control wheel gently.
