Z Axis Bearing Support
by epideath, published
I don't really like bushings so I will slowly be moving to bearings where ever I can. I liked Jetguys idea and it makes good mechanical sense. But one I didn't really want to modify my ToM permanently with the tubes and I would have to pull it apart more to do that. Two I wanted to get bearings on the Z axis. My first thought was to use a linear bearing and it still may go that way. But this seems to be working from my preliminary tests. I haven't done any hi speed tests or anything of the sort. Just a basic cube.
This may be a WIP not sure :) we'll have to see how this one works out and see if there are any improvements. If any one else builds this I would really like to know your results. This was designed for the HBP it won't fit with the ABP.

Well I can say that they are still working fine. But keep in mind i'm not printing on them all day either, or even every day. But i don't see any failures or cracks. I haven't had to change my z home setting so I will assume that there is no fatigue either.
I actually had purchased some from VXB http://www.vxb.com/ but some have gotten them from Ebay. I'm not sure if Makerbot sells them or not, but they are not a standard part on the ToM.
