I’ve already read all the lubing guide for bambulab A1, The y axis rails, the X axis Linear rails and the z axis Lead screws. Haven’t seen any lubing guide for the Z axis linear rod.
Yes the A1 is driven by a lead screw but a teardown video on youtube shows that the lead screws only drive the z axis and is it has no top berring it actually wiggles and is guided by a linear rod. I wonder why bambu doesn’t have a wiki for this. Maybe you don’t need to lubricate the linear rod in its entire life time? Or I’m the first one to talk about this.
Too simple, maybe? Wipe the rod down with a clean cloth and some IPA and then put a couple of drops of lightweight lubricating oil on the shaft and run the bearing through it a few times by hand…
the A1 mini has vertical linear rails exposed outside and is easy to lubricate. We cannot just leave the linear rods in the A1 with no maintenance. I think bambu needs to see this post.
