I started on the X axis of my kit tonight and ran into a problem that has me paused. The movement of the x-carriage is really jerky as if it’s catching on something. At first I thought It was a bad bearing so I started to take the x carriage bearings out to test them individually.
What I found was that the sticking/jerking only happens on one of the two 10mm smooth rods. All bearings travel well on one rod and all bearings stick/jerk on the other. I’m guessing the bad smooth rod is slightly out of spec and causing the bearings to bind.
Any advice about how I might be able to resolve this or get a replacement 10mm smooth rod, 370mm in length?
