Tinker Tuesday for August 27, 2024

This thread is for anyone working on personal projects to share their progress, and hold themselves somewhat accountable to a group of peers. We can coordinate weekly standup type meetings if their is interest.

Post your project, your progress from last week, and what you hope to accomplish this week.


Last week's thread was quite a bit less active than the original one, but I think this is an idea worth continuing, so here we are. Though one thing that might be worth discussing is the pacing of the thread. If there's not so much activity, maybe we can go from weekly to monthly, and if anyone want's to give weekly reports, they can do so under their project's top level comment. Let me know what you think!

I recently purchased a Bambulabs 3d printer, and while I have been loving the thing overall, the automatic filament switcher has been giving me some trouble. The "AMS" holds four spools of filament, and has a pretty clever design where it can switch between the materials mid-print, so you can have multi-color or multi-material prints.

My problem is, the 1st, 2nd, and 4th spools work perfectly. The third spools starts to ingest filament, then proceeds to grind it to shreds while not feeding.

I've disassembled, cleaned, and reassembled the thing four times now, to no avail thus far, but tonight I make attempt number five. Wish me luck?

Good luck! Is it position number three that's broken, or the spool that you have loaded there?

Position number 3, to be exact - tried a number of filament types including the ones loaded to the other feeds, and they all exhibited the same behavior. I suspect it's the hub where the four PTFE tubes are combined which must have some sort of blockage, despite being able to manually feed through it, since that's the only piece I haven't fully taken apart yet.
