11. MAINTENANCE
Given the machine characteristics, it is very important to periodically check the different components so we don’t lose
print quality and to avoid errors.
Rods lubrication
Oiling the rods from time to time is recommended, especially when they suffer from difficulties moving or make more
noise than usual. Place a few drops on the rods, and move the axes so that the mechanism distributes it uniformly.
The same process should be applied to the two Z threaded rods.
Filament maintenance
Filament spools should be stored in a cool, dry place as heat and humidity affects this kind of plastic. If a coil is not to be
used for a long period of time, store it in a sealed plastic bag.
Ensure that the filament is neatly coiled. A loose coil can cause it to curl incorrectly, and cause jerks affecting printing and
the machine components.
Cleaning the printer dock
After several prints, the hotbed glass gets dirty, and layers of adhesive coating, plastic dust and debris accumulate. To
clean the glass, it must be removed from the printer. The remains of the coating and dust are easily removed by placing the
glass under water with a little soap.
Any remaining plastic stuck to the dock can be removed with a boxcutter, being careful not to scratch the glass. Acetone
can also be used as it acts as a solvent.
12. TIPS AND TRICKS
There are certain things that we must take into account when using and maintaining the machine:
•
Do not spill liquids on the hotbed or hotend as they could damage the other components. To clean individual
machine parts, first remove them from the machine. The only advised product for improved printing adhesion is
the coating spray included with the machine.
•
If difficulties are encountered while removing the printed objects, remove the glass first to avoid decalibration.
•
Do not overheat the hotend. Although its maximun temperature is firmware limited, do not use other methods to
heat it above the established range.
•
Do not handle the electronic parts of the machine when it is on, it could cause damage to its components.
•
Do not turn off the printer immediately after printing. Allow some time for the fans to cool the different compo-
nents down.
