Ahhhh....
So. I changed to .5 and it still was bad. I watched the gear motion again, worked fine up until it would be coming out the end, and retraction it would turn. I disassembled the whole thing and hmmm. The set screw had come loose, the gear wasn't on there at all. So, fix that and I get out the best 15mm cube I've ever gotten. Pyramid! No dice. That one has a lot of retraction and flaws are revealed. I got a couple mm high on the hollow posts, very nice looking, no threads. Then it would jam, or something, just go to pot. At least once, and maybe always, it was mechanical. I used a screw I had on hand for attaching the bearing. It's a bit thicker than low profile so my bolts aren't as tight as they should be because it rubs on the heat sink. So once a screw worked itself loose attaching the heatsink fan etc. during the retract moves. Got that back on there, tried lighter retraction of .2 and .1. While nothing worked loose still bad results after a couple mm high on the posts. Setting aside for the evening I tried something simpler and now I have bed adhesion issues. However I see what looks like filament too high on the tip, near the ceramic. Looks like a leak. <sigh/>
Good night. Try again tomorrow.
