1. Regular Checks and Maintenance
IX. MAINTENANCE
Periodically, and this depends on the usage of the printer, it is necessary to perform some simple checks and maintenance. Some
of these actions may be needed to solve a problem like cleaning a clogged nozzle. When it is first used parts of the printer will ‘bed
in’ so perform these checks often.
Routine checks:
Re level the build plate
This has been described earlier but over time the level of the build plate can change so perform the levelling checks frequently,
especially if you are having adhesion problems on the first layer.
Clean the Build Plate
Make sure the surface of the build plate is free from dust and any other contamination. Do not use abrasive cleaners! Wiping it down
using a microfiber cloth with a little Isopropyl alcohol or a no residue window cleaner is recommended.
Check the Drive belt tension
Frequently check the tension on the X and Y axis drive belts and adjust if needed. It only takes a few seconds so it is recommended
to check this before each print.
Check the extruder gear
Over time the toothed gear on the extruder can be clogged with filament fragments. Remove and clean with a stiff brush, then replace.
Check for Play in the roller assemblies
It is important to keep the V rollers and the profile extrusions that they run in clean to ensure free running. Also periodically check
that there is no binding during their movement and there is no discernible play between the rollers and the profile groves that they
run in.
