My printer will feature LM8UU bearings/threaded rods for the z-axis and bronze sinter bushings on the x- and y-Axis.
As also, but not only, written here http://reprap.org/wiki/Lubrication, I know that one should:
- use machine oil for sinter bearings, if anything at all,
- grease on the 'more fluid' side for the linear bearings so that the lubricant stays eqally with balls on the upper and lower side
- and probably PTFE grease for the threaded rods (as for example provided by the Ultimaker UM2)
Is there a way to unify this or at least only use two lubricants?
I do not have the slightest idea about lubricants, I would not know what to actually buy if the combination would e.g. be machine oil and low viscosity grease. Do you have specific recommendations of what to avoid?
