Taz 6 Adjustable Y Bearing Mount

thingiverse

I noticed that the Taz 6 is designed with quite a bit of bearing clearance. See this video: youtu.be/18L_bJcZ_i8, which shows the original bearing holder. This results in a visibly uneven surface on printed parts. The idea here is to cut between the fins of the bearing so that the bearing can be compressed, and squeeze the bearing onto the shaft with clamping screws. So far, I've noticed a significant increase in drag on the shaft before the clearance is completely eliminated. It seems most of the remaining play is between the bearing and the holder. I think the solution to this is to fill the gap between the bearing and the holder with glue, and clamp it tightly to the shaft, then when the glue hardens, loosen the screws until the bearing drags only slightly on the shaft. After trying gluing the bearing into the sleeve, I improved the situation, but tightening the bearing enough to remove all play increased friction too much. I also found that there is much more play in the center of the bearings than at the ends, so the bearing is only really in contact with the shaft near the ends of the bearing. I've decided to stop working on this path to improving the printer because it's not yielding any better results.
