- Maiden voyage complete!
40mm/s @ 200mm/s^2 accel. Still have lots of work to do, but it's a start. And none of that matters right this moment...
Because it's printing! :D
www.thingiverse... for tons of detail and links to more info
Insanely cool. I have great respect for the effort you made to make this into a reality.
Thanks!
IT LIVES! Congrats! Now, for the fine tuning of the Tripteron mechanicals to ensue, though it appears even with the current issues you've mentioned previously, this has better quality than many "finished" 3D printers!
it's like a cartesian printer, but with extra steps. Nice work :)
It’s gorgeous!
People have been talking about building one of these for at least four years, but you actually did it. Holy shit, dude.
Yep! I saw a way I thought would work to organize everything, and worked at it a bit at a time. I started from scratch a bit over 3 weeks ago and have been trying various designs and iterations as I went, getting closer each step.
www.thingiverse.com/thing:1903757 has a lot of links including my RepRap Forum link that chronicles the design journey if you're interested :)
And you've actually documented the build. You truly are a unicorn.
Awesome! Great work. Nice to see some more interesting kinematic designs around.
That is a very interesting design. Mesmerizing to watch!
Thanks, I think so too!
What a little cutie
Surprisingly stable considering the number of joints between actuator and nozzle on each arm.
I thought the tolerances would cause too much slop in each axis resulting in a lot more z-banding.
Very cool build
Cool design! Seriously! However, it has a major downside which is probably inherent in the concept: since the joints at least of the z-axis are strained torsionally you're going to wear them out and eventually end up with an increasing amount of play. I'm not sure how you're gonna solve this. Would you mind elaborating on it?
just spitballing here, but if you keep the entire structure light enough you would only need to replace is every x hours. since joints can be had on the cheap you could view them as a disposable item.
It's definitely the primary engineering challenge, stiffness and resilience in arms and joints. However, the bearings (608ZZ) and axle (8x30mm 12.9 grade shoulder bolts) are nowhere near their loading limits, neither in preload compression, static or dynamic. The bigger issue is potentially the printed brackets housing them, but fender washers are used to spread the force, and the mechanical properties of PLA are easily capable of handling the loads involved.
It's not nearly as big of a deal as it seems at first, but the 608ZZ bearing races would be the first to go, and are of course cheap and replaceable if needed after a 10000 hours or whatever lifetime you achieve at the preload compression you use :)
amazing!
I'm working on one tripteron like yours. i have builded everything, printed parts in abs like resin, very tough, now i'm ready to build firmware.
I'm loading on a mks robin e3, with a 3d touch instead of ir probe and sensorless homing. Can you share settings for max dimensions and accelerations and speeds? Thanks in advance @Apsu , you've done a great work!!!
nice design bro
Oh it's you!
It is me!
@@Apsuity is u!
Are you still working in this and is there firmware available really thinking about building one.. :)
Wow is amazing
What microcontroler are you using for print???
That was a MKS Sbase, which is an old smoothieboard clone. But it had completely stock firmware, because this machine is fully Cartesian. It doesn't look like it at a glance, but if you watch my Q&A stream I explain how it works.
More focus on the mechanism as a whole, and not on the head. We all know 'hot plastic oozes out of here'. What we wanna see is the this _amazing_ looking mechanism operate!
Just hold the camera still for more than 1.5 seconds and let us see it operate from a few angles.
hah! I didn't expect to get quite so many folks who weren't already following my forum/IRC and hadn't seen all the other pics and videos prior to the one where it was printing. I'll take some more motion-only videos of it soon.
Awesome!
I did you one better. I did a livestream showing lots of motion, talking through the mechanism and construction and showing lots of footage of it in motion :) Link is ruclips.net/video/wJz5fC15PbE/видео.html or just look at my channel feed
Forgive my ignorance, but, what is the advantage of this mechanism?
There are many potential advantages which are discussed in the RepRap forum thread linked on the Thingiverse page in the video description, but the short version is that it's parallel Cartesian with a fixed platform that is relatively cheap and simple to build and modify.
I don't know why I accidently not read the description. Thanks!
I don't know if you'll ever see this Eve, but how long are the lengths for the arms. It looks like double.
Hi! BOM is actually available along with the models for this build, here www.thingiverse.com/thing:1903757
@@Apsuity Thanks!
Hola cómo controlas los movimientos? Que firmware tiene?
Are you using thrust bearings in the hinge? If not how are you getting rid of the play in it?
Nope, just using a back-to-back preloading arrangement of radial deep-groove bearings, which is precisely how play is taken up in radial bearings. i.imgur.com/o2IsTWH.png is the cross-section, which was designed to always compress plastic between metal, for minimal creep and plastic deformation.
@@Apsuity oh so you used 2 bearings with them slightly offset from each other?! That's cool
I don’t understand, how the geometry is setup, that’s insane
All I can say is WOW!
:D
firmware u used ??
hello! is that plain glass? how did you get working the ir sensor with that surface??
The sensor uses 2 IR LEDs offset and modulated, and is capable of dealing with a huge variety of surfaces. The only caveat with glass is that the surface behind it isn't of lower emissivity, so I just clipped plain cardboard behind it. :P
Apsuity thanks!!!
dafuq is dis
A 3D printer! It's my implementation of the Tripteron motion platform, and as far as I know is the first (and only, so far) ever made. Tons of info here forums.reprap.org/read.php?166,719575 and www.thingiverse.com/thing:1903757
you could have made the arms a lot thinner then it would look descent
@@NSAwatchesME : The problem? Then you can't make robust hinges, etc. Looks aren't important. FUNCTION is.
