Ultimaker 2+ Connect user manual 29
5.3 Maintenance schedule
To keep your Ultimaker 2+ Connect in optimal condition, we recommend the following maintenance schedule,
based on 1,500 printing hours per year.
If the usage frequency is higher, we recommend performing more frequent maintenance on your printer to
ensure optimal printing results.
Maintenance actions shall only be performed by an adult. Carefully follow the provided instructions. Where
possible, ensure the printer is turned o before performing maintenance. Otherwise, if the printer is connected
to the Digital Factory, ensure the Ultimaker 2+ Connect is unavailable to accept new print jobs from starting
remotely through the Digital Factory.
For most maintenance actions, it is required to remove the Air Manager cover and/or front enclosure in order
to reach the parts of the printer.
Every month Clean the printer Keep the Ultimaker 2+ Connect clean for optimal printing results. This includes:
• Cleaning the glass build plate
• Removing degraded material from the outside of the nozzle
• Removing particles from the inside of the Bowden tube
• Cleaning the inside of the printer
• Clean the Air Manager components
Lubricate the axles Apply a small drop of oil to the X, Y, and Z axles. Move the print head and build
plate to equally distribute the oil.
Only use the supplied oil, as other oils or grease may aect the coating of
the axles.
Every three months Check for play on the axles The X and Y axles in the frame should only rotate, not move back and forth.
Firmly attempt to move the axles individually. If there is play, follow the
instructions on the Ultimaker website to correct it.
Check the tension of the
short belts
The short belts attached to the X and Y motors should be tight to correctly
transfer the movement to the print head. If the belt tension is too low, follow the
instructions on the Ultimaker website to correct it.
Lubricate the lead screw
of the Z motor
Apply a small amount of grease to the lead screw of the Z motor. Move the build
plate up and down to equally distribute the grease.
Retighten the hot end
isolator
Insert the hex screwdriver into one of the holes of the hot end isolator and fully
tighten it. This prevents material leaking between the hot end components.
Every year Clean the feeder Small lament particles can gather on the feeder’s knurled wheel. Unload the
material and open the feeder to clean the inside with a small brush. Follow the
instructions on the Ultimaker website.
Lubricate the feeder gear Remove the feeder from the back panel to access the feeder gear. Clean it rst,
then apply a small amount of grease to the gear. Follow the instructions on the
Ultimaker website.
Replace the Bowden tube Materials can slightly scratch the inside of the Bowden tube and the ends of the
tube can get damaged by the tube coupling collets. It is advised to replace it
after one year of printing.
