For the most part My AO-100 is printing perfectly. There does seem to be a little play in the axis now that I have about 14lbs through it, but even when things were new I was experiencing varying layer protrusion that seemed to happen in a pattern. You can see it good in the photos below.
It seems to appear every 5 layers or so and gets worse as I decrease layer height. I have noticed that since the beginning, the Acme Rods so seem to not be aligned good and they wobble when turning. I was told that upgrading to the X end clamp 2.0 could fix this, but have yet to print the new clamps. What are your thoughts on the matter?
