Maintenance/Optimal operational tips
The FELIXprinter is an easy product to maintain and clean. To keep enjoying your FELIXprinter and
ensure optimal print performance, regular maintenance is very important.
12.1
General tips for optimal operation
-
Make sure the filament enters the hot-end is clean from dust. You can do this by letting it run
through a piece of sponge before it enters the hot-end. You will be surprised how much dust will
accumulate during a 5 hour print. That would have all entered the hot-end and formed a layer of
contaminants, which would interfere with the heat going into the filament. A filament-cleaning
accessory is provided, as described in Chapter 9.
-
Do not use too high temperatures. They will make the filament decompose and contaminate the
inside of the nozzle.
-
Do not leave the hot-end heated for hours. The filament might decompose after leaving it at high
temperatures, leaving a layer of contaminants behind in the hot-end nozzle.
-
Use good quality filament.
12.2
Cleaning
-
To ensure good bed adhesion of prints we recommend cleaning the heating bed with spirit, alcohol,
thinner or nail polish remover. We recommend doing this before each print, especially for long prints.
-
Be careful not to get any liquid onto the electric board, as it can damage the electronics permanently.
-
Dust the printer off with a moist piece of cloth.
12.3
Regular maintainance
-
Lubricate the vertical spindle and the linear railings; we recommend doing this every 3 months.
-
After some time the belts might lose a little tension. Tighten the screw in the belt tensioning part
until a healthy tension is back on the belt. For an indication of how to tension the belt check out this
