A way to get faster printing with Taz 6

Hey guys! I’m a PhD student at the University of Michigan and I’ve been doing research on how to make 3D printers print faster. We’ve come up with a software solution called Ulendo that seems to work really well. I’m interested to hear what you all think about it. Check out the video: https://www.youtube.com/watch?v=w-_gY23yGwY

We’re also doing a beta program right now so you can sign up to try Ulendo for free on our website: https://www.ulendo.io/

(There’s also a ton of other info on the site.)

So does this replace the printer’s stock firmware? Does a specialized slicer need to be used?

Ulendo Software is a one-time software purchase, delivered on a Raspberry Pi device.

We’ve actually set it up to run alongside the printer’s firmware. So once you set up Ulendo, you can either run a print with Marlin or run it with Ulendo. This gives you the option to use it when you want.

And no specialized slicer needed. Just save the Gcode with your favorite slicer on the Pi and print.

Interesting… does this only change non-printing travel time or does it affect travel time while laying down filament?

I did look at the beta, but noticed it currently requires TAZ 6 (I have a Workhorse & Pro).

Also… you might want to look at OctoPrint / OctoPi. OctoPi is a Raspbian OS image meant to act as a print server/controller so you don’t have to keep a computer tethered to the printer and you can control it via any web browser… in addition to remote monitoring (you can use a camera to make sure the print is still going ok and cancel it if you find your making a plate of spaghetti).

This is the sort of thing that might work well as a plug-in module for OctoPrint. (OctoPrint is the software … OctoPi is the OS image for the Raspberry Pi that runs OctoPrint).

@TheVirtualTim it affects travel time while laying down filament. And we plan to expand to other printers soon, so we’ll hopefully have support for the Workhorse and Pro soon.

Connecting Ulendo with OctoPrint is a great idea and we’re actually already working on it! Stay tuned for updates on that as well

I’m in Dearborn… not so far from Ann Arbor. So if you want to run tests on a TAZ Workhorse or TAZ Pro … I have one of each and am happy to run jobs.

And for grins… the spacetime interval is ∂s = √ ((c∂t)^2 - (∂x)^2)

Which says … as velocity increases towards the speed of light… time slows down.

If you can get the printer to move at the speed of light… then the print job will finish instantly. (With apologies… the physics/astronomy geek in me couldn’t resist.) :smiley:

Ok, so my tongue is firmly pressed in cheek … but on a more serious note I am very happy to learn that you are working on a way to increase print times and looking forward to reading about your progress.

Would this shorten the life expectancy of the machine itself- wearing out certain pieces a bit quicker than normal? On my machine I had to slow it down a bit because some of the 3d printed parts started to crumble due to high usage. (the bu**er of it is that you need a 3d printer to print out the bits that’s broken?- joke.)

This is a great question! We haven’t done a detailed long-term study of how Ulendo changes the life expectancy of the machine, but my inclination is that it would not necessarily shorten the life expectancy.

The software actually modifies the commanded trajectories to prevent vibration on the machine, so, for the same print settings, printing with Ulendo would lead to less vibration than without, which would ideally increase the life span of the machine. Of course, then the question is that if you slowed down the machine, would this still be the case? And if so, what would the speeds that you run Ulendo at need to be to get the same wear over time? That, we don’t know yet.

If anyone is interested, we wrote a white paper that has some more details on how it works. You can download for free at: https://www.ulendo.io/download-white-paper
