That’s it! You have just finished assembling your very own Litto 3D printer. However there are just a few things to
check before you power-up the printer for the very first time:
1. Make sure all screws and components are properly screwed down and secured.
2. While manually moving the the gantry system (extruder, belts, pulley, smooth rods, bearings), all components
should operate smoothly and not interferre with one another. Check that all sets screws on the pulley are
tightened, and all belts are aligned so they are seating fully in the teeths of the pulley.
3. All electronics are properly plugged in and seated into their correct ports. Make sure there are no exposed
wires in contact with electronic components, and the electronic cooling fan is properly mounted and directing
airflow to the Pololu driver.
4. Make sure there is no foreign objects along the path of moving components. Avoid using lubricant on the
linear bearing (Z Axis + Carriage). Most lubricants (especially ones that contain propellants) might absorb dirt
and become more viscous over time, which can cause more friction and cause damage to the bearings.
