Actually made something useful with my 3D printer.

First test print. :geek:

AMS multi-spool thingy showed up. For now the printer's setup in the sun room until I can figure out how it'll fit in the workshop. I wanted to test it's ability to switch spools on the fly (during printing).

Sumbitch, it really works! :geek:
Looked on Makers World for something easy that wouldn't break the bank. Someone had the special tools to repair the AMS if (when) it breaks. 1 hr and 3 min later...

The letters didn't come out perfect, but I think that's more on the tool designer than the printer. At any rate, I selected green tool and grey letters. The AMS hub did the trick... no intervention on my part.

one tip that may save you a lot of headache: if you start getting issues with stringy prints, where the adhesion to the plate is poor, wash the plate with dish soap and a blue scotch brite sponge. the issue is likely grease from hands or remants of old prints. Don't use hand soap as that may contain lotion additives. rinse the plate well with warm/hot watter and let it dry. We have a number of plates cleaned and ready for when a refresh is needed.

Another item you may want to consider is a filament dryer. All of these plastics absob water and then there are issues with quality.

Thanks for the cleaning tip. I'll keep that in mind.
The AMS has a built in heater/drier with desiccant. It's supposed to maintain a constant 55°C inside it. Any other spools will be kept in their sealed packaging.

that is nice. my AMS opens to air. Here is what we do with the purged filament waste: use silicone molds to mold colorful shapes. My kid then takes these to school and gives away to friends.

When I was taking an intro to Engineering class, I designed a little chopper motorcycle.

The printer switched spools for the support material. When the print was done the bike was put in a chemical bath and the support material dissolved, leaving a motorcycle that had spinning wheels and turning triple trees.
 
Not proud of this one, but figured I post for the hell of it. My butterfly valve shaft seals started to leak enough to upset the idle. The one on the right is the biggest offender. While I brush up on the community's wisdom on how to change the seals out, printed a cap and used ThreeBond to seal it over the end of the shaft. The problem with idle improved significantly.

Nice! I printed mine calling for "F" drill/.257 holes and used 6mm stainless button head screws and nuts to bolt to my basement workbench pegboard, but man are they a pain to tighten when the bench is up against the wall.

i found the model on the bamboo maker site and printed out of PLA Tough +. lets see how it holds up
