This is for anyone that has upgraded their TAZ with hardened rails and bearings…
What bearings did you purchase and where did you source them? Do they run nice and smooth for you? How do you oil / grease them?
I went with Misumi bearings and rails and have found the bearings, especially on the Y axis to run a little rough. The roughness translates to a stippling or texturing on the side wall of my parts when the Y axis is moving.
I am going on the assumption that this is caused by a bearing problem. If anyone has other ideas, I would love to hear them.
It is difficult to get a good picture of this but here are a couple of examples. You can see the problem more clearly if you view the full size image.
X axis is nice and smooth as it should be.
Y axis has this odd textured look.
