  • Page 19: Chapter 2 - Printer Preparation

    Chapter 2 – printer Preparation PREPARING THE PRINTER This chapter describes the procedures that must be followed to configure the Olivetti S2 printer correctly and set it up properly for the following printing phases. Unblocking the extruder assembly To protect the printer during shipment, the printing carriage is blocked into position using bands.

  • Page 20: Aligning The Printing Table

    Aligning the printing table To obtain good printing quality it is of fundamental importance to ensure that the first layer deposited is distributed uniformly on the printing table. For this purpose it is essential to ensure that the printing table is aligned correctly. Although the printer has already been set up in the factory it may be necessary to repeat this operation due to the stresses caused by transportation.
  • Page 21 Figure 2-4 Blue-coloured display screen after Bed Setting is selected Press the jog dialer again. The extruder assembly moves to the first Adjustment position (there are 5 in total). Try to pass the 0.10 mm feeler gauge supplied between the Extruder 1 nozzle and the tempered glass. If the feeler gauge moves freely between the nozzle and the glass, you must work on the reference self-locking nut turning it in the clockwise direction until no light passes between the glass/ gauge/nozzle.
  • Page 22 Adjusting nuts Adjusting nuts Figure 2-5 Adjusting nut positions After the first adjustment is complete, press the jog dialer again. The extruder assembly moves to the second adjustment position. Now repeat the adjustment as described at point 4, and press the jog dialer to bring the extruder assembly to the next adjustment position.

  • Page 24: Adjusting The Printing Nozzle Heights

    Adjusting the printing nozzle heights To ensure correct printer operation and optimise printing quality, you must adjust the printing nozzle heights. Although this adjustment has already been carried out in the factory, it may be necessary to repeat the operation due to the stresses of transportation.

  • Page 25: Adjusting The Height Of The Second Printing Nozzle

    Figure 2-7 Using the 0.10 mm feeler gauge, adjust the distance between the nozzle and the table WARNING: Incorrectly executed height adjustments may result in bad printing quality or, in the worst case, provoke a collision between the hot-end and the printing table, causing damage to the machine. WARNING: The height adjustment operation must be carried out with the nozzles in a clean condition, free from plastic residues.

  • Page 26: Loading The Filament Bobbins

    Loading the filament bobbins To load correctly the material filaments to be used for printing, follow the procedures below: Insert the bobbin of material onto the special bobbin supports, keeping the thread oriented towards the lower opening of the feeder. This means that, when looking at the machine from the back, the bobbin for extruder 1 will rotate in a clockwise direction, while that for the extruder 2 will rotate in an anti-clockwise direction.

  • Page 31: Preparing The Printing Table

    Printing using dual extruders The Olivetti S2 printer is able to print with both extruders 1 and 2 active, enabling you to print workpieces in two colours or composed of different materials. To print in two colours and obtain good results, you must calibrate both extruders.
  • Page 32 To ensure correct calibration: Load the material for printing into both feeders. Select the file from the SD card. Give the print command. The printer proceeds to print a first square with extruder 1 and then a second square with extruder 2. If the calibration between the two heads is perfect, the two squares will be perfectly superimposed, otherwise there will be an offset between them.

  • Page 40: Gcode Printing

    Printing using two extruders To print using both Olivetti S2 extruders, the first thing to do is check that the second extruder is calibrated correctly with respect to the first extruder following the procedures in the section on printer preparation.

  • Page 41: Suspending And Interrupting Printing

    Figure 3-2 Dual extruders in slicing SW Refer to the Slicing SW manual for the correct settings for the dual extruders and based on the type of result you want to obtain. Once the GCODE is generated for the two extruders, all you have to do is issue the print command using the procedures already described for using a single extruder.
