My CoreXYUVAB as of today
-
Just published a YouTube video of my machine's current state of evolution if anyone is interested. https://www.youtube.com/watch?v=IG3AGKDzdH4.
I've attempted to explain the machine without using words - hope it works. It's best viewed on something a bit bigger than a 'phone and better still with reasonable speakers. It'll take 10 minutes of your time to watch it.
-
Pretty darn impressive! Thanks for posting!
-
That's a nice video, thank you! I especially like the fact that all elements have their place, especially the Duet elements (hinged expansion boards) and wiring.
-
It's an impressive piece of machinery. I'd be interested in seeing more of the things you produce with it.

Thanks for sharing @deckingman! Curious about the nozzle wipe procedure. What is the material/thing that you are wiping the nozzle accross? Thanks again!

It's a strip of silicone rubber, pressed into a slot that I machined into a piece of aluminium.

Congratulations!!! .... is a monster !!!

I love the bit with the £1 coin

Thanks. It shows that the load balancing gantry does what it's supposed to do - shame there are no gains in print quality though
-
Excellent printer Ian, I love the attention to detail.
There is a lot that can be learned from this printer you built.
Congratulations!

Thanks Tim. I hope people find it educational - that's the main reason why I publish this stuff on YouTube and my blog - so that others might learn something from my successes and failures.
-
@deckingman I find that I learn much more from failures. There is the added plus of the humbling that goes along with said failures....
I've learned a bunch over my lifetime
-
@timcurtis67 Oh yes. Also, no matter how old one becomes, one never stops learning. Which means one never stops having failures.
There is a saying in the north or England that I quite like and which is "If tha's never made a mistake, tha's never made owt". Which translates into "If you've never made a mistake, it's because you've never made anything"

A good old yorkshire saying Ian

@Dougal1957
True.But the best sayings emanate from Newcastle. I married a (near enough) Geordie lass - took me ages to work out what ""How man, had ya pash, divvin' be a workyticket." meant.
-
@deckingman Jeez Ian I am not surprised lol
-
@deckingman Ian something OT, but I know you're interested in mutlicolor/multimaterial printing, this may be of interest for you: https://wyss.harvard.edu/news/multimaterial-3d-printing-manufactures-complex-objects-fast/

@JoergS5 Thanks for the link. Now that I like!
Multi-colour/multi-material printing aside, I've always thought that there must be a better way of laying down molten plastic than trying to control what comes out of small nozzle by changing how we ram the stuff in to it. Replacing conventional extruders with fast switching solenoids is akin to how the internal combustion engine has evolved for using old "analogue" carburettors, which relied on a given (pulsating and variable density) air flow to "suck in" a given amount of fuel, to using electronically controlled fuel injection systems to deliver a very precise qantity of fuel based on information received from a vast array of sensors.
I truly believe that the way forward is to do away with conventional extruders and replace them with something akin to what you linked.

Ian, I´v learnd a lot bevor from your blog. Special about multicolor and the Diamond Nozzle.
Today, for me it worked not... often it is clogged and I don´t know why... not really.
My Idea, special in mutimaterial printing is... only two materials... but with a very small nozzel.
So the volum at the nozzle inside is extremly minimal.. and so ... perhaps... it´s possible to come like direct injektion.The 3-diamond nozzle contains whereby the 3 E3D´s more machanical space and therefor more Material.
Equivalent bigger is your 5-Nozzle and so.. more material.If you thing about how many material come through the small hole in the front of the nozzle... you can imagine, wich impact has a little more volume at the inside.
Thats my Idea for an very, very small Nozzle, with only two E3D and a very compact dimension.
I don´t know if it´s right and if it works... but that my Idea. -
I see the hot end with the metrol switch.
Where have you find the soo small oil filled bronze bushes and steel dowels ?
