⬢Cool down the printer. Go to More > Temperature > Cooldown. Wait till the printer is cooled down!

Make sure the heatbed is cooled down to ambient temperature.

⬢Spegni l'interruttore di alimentazione (simbolo "O").

From now on we will demonstrate the lubrication of the Magballs on the printer with the lights on for better visibility inside the printer. Please note, do not switch ON the printer. The printer in the pictures is shown with the lights on for better visualisation for customers.

Passo 5 Rilascio del blocco dell'apertura dello sportello

⬢Open the lid.

⬢Con un cacciavite piatto, allenta il blocco di apertura dello sportello ruotandolo di 120° in senso antiorario.

Il finecorsa Door-opening-stopper è una parte stampata, basta una leggera torsione per allentare questa parte.

Passo 8 Print head releasing

⬢Prima di procedere, si consiglia di proteggere il piano riscaldato.

Make sure the heatbed is cooled down to ambient temperature. Place the cloth approximately to the front center part of the heatbed.

⬢Posiziona il panno antipolvere all'incirca nella parte anteriore centrale del piano riscaldato.
