C2 User Manual, Release 1.0.0
• Make sure there are no broken pieces of filament within the extruder.
• Make sure all cords are neatly tucked away to avoid unnecessary accidents while the printer is in operation.
• Make sure all of your software is up to date (on screen prompts will let you know when updates are available,
but only if you are connected to a Wi-Fi network).
And to ensure the best 3D printing experience now and in the future, use the following Robo C2 maintenance tips
regularly (every 6-12 months, depending on use):
3.2 Cleaning the feeder gear
Steps to take to clean your feeder gear
1. First, turn off your machine and remove the extruder cover.
2. Once that is off, go ahead and use a toothbrush to brush the feed gear to remove debris.
3. Rotate the feeder gear by turning the motor shaft by hand and repeat steps until the entire feeder gear is cleaned.
4. Place the extruder cap back onto the top of your extruder assembly and plug in Robo C2.
3.3 Lubricating the axis
There are two types of linear rods, and two types of bearings in Robo C2, and they must be lubricated differently to
ensure best prints.
White Lithium Grease
• The rods that carry the extruder head are ball bearings and should be lubricated with a white-lithium grease
to ensure smooth travel.
• The z-axis lead screw also needs a white lithium grease for lubrication. Dap a small amount onto the rod,
and let the printer move up and down from the next print to lubricate itself.
3-in-1 Oil
• The x and y brackets have a smooth bushing inside of them, and need to be lubricated once every 2-4
months. Wipe down the build up that these bearing produce on the rods over time with a cleaning agent.
The bearings can be greased with a few drops of 3-in-1 oil, or sewing machine oil to lubricate sufficiently.
3.4 Cleaning the print bed surface
• The Robo C2 print bed surface is a sheet of black painters tape. Make sure to clean it with rubbing alcohol to
ensure your print sticks to its surface.
• After 15 or 20 prints, you may need to replace this sheet if you see that your prints are not sticking to it. Ensure
that the print sheet is laid completely flat on the build platform, and that it is flush and level across the surface.
• When you run out of print surfaces, you can order more at www.robo3d.com.
• When removing and replacing the entire print bed, double check that its magnets align with the magnets on the
platform to ensure it is seated correctly. Build platforms that aren’t seated correctly will result in failed prints.
