Now finish the housing, and hang a load on it, like the worm of a BS-1 while making another worm to replace the crappy worm in the Chinese BS-1. That worm is doomed to a higher wear rate, a fact I'm becoming aware of as I exercise this BS-1 servo for tuning. That is why I bought the ender3, but I was using O.P's code which was crappy code IMO. Turns out the ender3 can make stuff a heck of a lot better that the code I could DL from thingiverse. I now have the extruder motor on the x carriage, moving a modified stock hot end, and while its slower than some because the heating is only once the filament is in the nozzle, dozens of times more dependable than the stock setup. No clogging from cold filament because the hot stuff backs up into the heat sink and freezes. I think this loose ring idea has the most promise of making a long lasting drive, and shorter axially than any design so far. Please continue.
