I’ve been thinking about a 3d printer filament buffer for a while, but haven’t really made the time to actually solve this problem, mostly because my multi-material printing has, to date, been pretty minor. That’s not to say I haven’t been using my MMU, only to say that so far my prints have primarily needed tens of tool changes rather than hundreds. At this scale, my “non-buffer” buffering solution worked reasonably well. I’ve only had one or two jams, and it wasn’t that big of a deal. Well, I decided to try a “big” project, and printed some miniatures with soluble supports which resulted in 216 tool changes. This, I found, is why the filament buffer exists.

After a week of troubleshooting, I’ve finally gotten my printer back up and running again. If you read my last post, you’ll remember that I upgraded my Prusa with the new MMU2S, and while building the upgrade itself wasn’t too bad, getting everything working again afterward didn’t go well. I didn’t document the time I spent troubleshooting, taking things apart, and putting them back together, but I did document the original build, so here’s the image montage of that, then I’ll talk through the steps I took to get it all back working again.
Prusa Multi-material Upgrade – Part 1
Over the weekend, I decided it was time to build my long-awaited multi-material upgrade for my Prusa 3d printer. I had planned on ordering this way back in March, but the combination of my funds and other things I wanted to order at the same time being out of stock stayed my hand. Still, after lots of different delays, I finally got around to ordering it and building it. Continue reading Prusa Multi-material Upgrade – Part 1
