I will give that a try. I tightened up the belts, “polished” the conduit, tightened the middle assembly just a touch, and one of the roller blocks just a bit.
Seemed to be a little better but I noticed one point in the motion where it was bad. It appears that I managed to get the seam next to the bearings and there is a little rough spot. I will work on that area a little bit and also run a program. I really need it to stop raining here so I can get my bench top and finish this thing up.
