That be great, I dont' even know how to describe this situation now.

The spool with the yellow work flawlessly while, the spool with the black tpu would fail 1/5 time during the rewind process. I already replaced the parts so all the bearing would fit snuggly (printed with 0.4 nozzle at 0.2 layer height). Here is my observation.
issue 1: If the track is extending to the highest point occasionally it will fail to unwind, that leads to the stray filament and eventually lead to filament unwind outside the spool will loop around the shaft.
issue 2: Sometime the mechanism will unwind the filament pass a bit too much, beyond the hob gear.
issue 3. once a while the spool will unwind fully pulling the filament all the way back.

This is my observation. Can't wait to hear back from your experience printing with it.

Sounds good :) this is a work in progress. At least one of the spool is working now. Thanks again for the tips you pointed out so far, they have been very helpful.
