Lubricating - CraftBot Flow User Manual

8.2. Lubricating

The CraftBot printer should be lubricated at least once after every 50 hours of use or every 6 months.
Tools needed for lubrication:
• PTFE based spray lubricant or grease
• 2 separate lint-free rags or thicker stronger paper towels
• Personal protection such as gloves and safety glasses/goggles
• Lighting to see the interior of the CraftBot correctly (lamp)
1. Move the build plate and the extruder to the „Home" position.
2. Once the extruder and bed are in the home position, turn the CraftBot printer off and unplug it from the
electrical outlet.
3. If you look beneath the build plate you will see three rods that run vertically in which the build platform moves up
and down on. The two outside rods are smooth and the center rod is threaded. These three rods are known as
the "Z-axis rods".
4. Place a folded paper towel or a lint-free rag behind the center rod. This rag is used to protect other areas of the
printer from any over-spray that may occur.
5. LUBRICATE ONLY THE PARTS RECOMMENDED IN THIS MANUAL!
6. Spray the threaded Z-axis rod at a relatively close distance to reduce over-spray. Make sure the lubricant
reaches the inside of every thread (if using grease, spread with hand wearing gloves).
7. Make sure not to over-lubricate, spray only the minimum required amount!
8. Do not spray the other two rods directly! Spray the towels and wipe it onto the rods.
9. Remove the rag from the CraftBot interior.
10. Plug in and power up the CraftBot and move the build plate to the lowest point (go to Axes menu, and press the
Z down arrow until the bed reaches the lowest point).
11. Turn the CraftBot printer off and unplug it from the electrical outlet.
12. Place a second clean rag on top of the heated build plate to protect the components and Kapton from any over-
spray.
13. Repeat the process for the top side of the Z-axis rods the same as you performed on the bottom side:
protective rag behind threaded rod, spray, wipe excess lubricant on other two outside rods.
14. Power up the CraftBot once again and raise the build plate back up to the highest position (set the X, Y and Z to
the home position).
15. Turn the CraftBot printer off and unplug it from the electrical outlet.
16. Wipe any excess lubricant off from the bottom side of the Z-axis rods.
17. Power up your CraftBot once again and move the build plate back to the lowest point.
18. Turn the CraftBot printer off and unplug it from the electrical outlet.
19. Wipe any excess lubricant off from the top side of the Z-axis rods.
20. Power up the CraftBot once again and raise the build plate back up to the highest position.
21. Turn the CraftBot printer off and unplug it from the electrical outlet. The motors will now disengage so that you can
move the extruders freely by hand.
22. Use an oiled rag to lubricate the X and Y linear rails. Do not spray from above! Move the extruders back and forth
by hand to both extremes of the axes. When the extruders move absolutely smoothly you are finished.
