A3X Driven Support Shaft (TPU)

After weeks of testing, I happily introduce the A3X Driven Support Shaft! I was tired of seeing tangles in my AMS randomly at the worst possible times, so I set out to find the cause and hopefully, a solution. What I found was my AMS driven support shafts on slots 2 and 4 were not always “gripping” the spool as the machine began to roll the filament back up. The timing was, ever so slightly, off which would cause a bird nest of filament inside the AMS. Sometimes the machine could recover, however, other times, it could not. Therefore, I would be left with an error code and a paused print job. To remedy this, I installed a brand-new driven support shaft from Bambu Lab, but it did not fix my issue and slot 4 (I used it exclusively to determine the fix) continued to give me trouble. Thus, I set off to create my own driven shaft and to be quite honest, I was surprised when it actually worked out after having the issues for so long. The A3X Driven Support Shaft was born.
