05.1 Removing objects and cleaning the build plate
The roughness of the build plate on the Blocks Zero provides optimum adhesion. It is not
necessary to add glues, lacquers or other similar products, just ensure that the plate is lev-
eled and at an ideal distance from the nozzle. To remove the printed objects you can bend
the plate slightly or use a spatula or x-acto. It is advisable to clean the lament residues on
the plate between prints. To clean it you can use water or alcohol and can also resort to a
spatula or x-acto if necessary.
05.2 Cleaning the Nozzle
After several prints it is normal for the nozzle to show some dirt due to the accumulation of
plastic debris. To clean it it is necessary to set the nozzle temperature to 220ºC. After reach-
ing this temperature, the operator can use a dry cloth or cleaning paper to remove the dirt.
05.3 Firmware updates
Go to the product page on the internet where you can see the latest rmware version avail-
able. If the version on your machine is older, you must download the HEX le and if you do
not have the Cura software installed, you must do so. To upgrade the rmware, you need to
connect the printer to a computer with the USB cable provided with the Blocks zero. Then
execute Cura and select the Settings » Printer » Manage Printers menu and then select
the right machine and click Upgrade rmware » Upload custom rmware. Select the
downloaded HEX le, wait for the upload and press OK.
05.4 Rod lubrication
To lubricate polished rods, the operator must place two to three drops of machine oil on
each rod. To lubricate the threaded rod that causes the print head to move vertically, a little
grease must be applied.
05.5 Belt tensioning
Over time the belts may lose some tension. To adjust the tension, just adjust the two mov-
able pulleys, one for the printing platform and one for the print head. The operator must
also ensure that these are aligned between the pinions and the pulleys. (To learn more
about belt tensioning, see page 65 of the TIPS section of the Blocks Zero assembly guide.)
