Our Deltabot progress

Hi folks,

Yes, you might have thought the Delta bot design is dead-in-the-water, but its quite alive actually and still under active development. The calibration issue is solved now, the extruder had some setbacks most of all due to sheer lack-of-time, but the software is progressing. Its now in its integration stage.

However, to tease you folks a bit, i've tried to let it draw some images. See the Delta wiki page.

With regards,
Reinoud and Torsten

Nice, any update on the firmware? I am building a Delta and would like to use your firmware with it if possible. Thanks, great work!

Rob

The firmware is still a work-in-progress... that's its main problem :-S Its code is still very volatile. I'll see if i can release it soonish.

What is your delta looking like? Is it stepper based? Is it a real delta or a 6 legged platform?

With regards,
Reinoud

It uses steppers and is very much like yours but uses gears instead of belts. I have everything cut except the upper arm/gear mounts which I will finish tonight and it should be assembled and moving by tomorrow.



Does your code interface with replicatorg or something else? I will need to modify the code for my own use anyway but if I had even a half-way working starting point that would be great. I am planning on using http://deltafimware.googlecode.com/ unless there is something better.

Thanks,
Rob

Hi Rob,

nice design! Hmm... we might borrow some ideas

As of the firmware, that link you are referring to is an ancient version of our firmware. It is, just as the current one, communicating with the S3G protocol.

I'll see what i can do for the firmware.

With regards,
Reinoud

It's assembled, now it just needs some code to make it move...

However, to tease you folks a bit, i've tried to let it draw some images. See the Delta wiki page.

I saw that!

Extraordinarily nice bit of work, guys! Don't forget to ping the other devs working on Δ-bots in reprap-dev, btw. (This forum actually should be subsumed into reprap-dev, since you guys are devs who keep doing dev.)

Reinoud, Torsten, Rob, could you upload files for your machines to the wiki? I think Spacexula and I will want to do up a blog post on them, and the files are one of the important bits.

Remember, you're all RepRap developers (once you've joined the super-secret developer mailing list), and the wiki, RepRap.org, [reprap.org] is for everyone and everything!

Rob, btw, is that waterjetted-aluminum? It looks very cool.

Also, do you think your machine will need torsion plates / cross-bracing on the three pillars?

I wish I had access to a waterjet It was cut on my Taig mill. I will post some plans after I get it moving and see if it needs modifications.
The threaded rod seemed pretty stiff at the store but for that length there is a little bit of movement. There were some that were about twice as thick, I may try those.

Thanks,
Rob

Hello,

i dont want to bother you, but I'm very interested in the progress of your delta reprap and very avid of any information.

Have you managed yet to get some objects 3D printed, last thing I saw was the plotted image, which looked already very promising?

Regards & thanks
Claude

I got a bit further with the Delta Printer but it wasn't pretty. If anyone is interested I have more info here.

(Just seen it on Hackaday)
I missed that you made a working firmware ! I believed it was the biggest gap to print with a deltabot...

And when reading that the laser attempt wasn't as good as expected I thought "lets put a bowden on it !!" ^^
(in case a little stepper is to heavy for the arms)

Back again after quite some time of inactivity! Yes i'm still busy with the Delta bot. In fact i'm busy rewriting the firmware and the software in general. We've been both far too busy but our goal is to have it print in the next few months for real!

The state of the bot is that i can hover at resonably high speed under 0.1 mm above the platform. The extruder motor part seems to be working and the extruder itself has been designed but not built yet. *sigh* i wish i had a 3d printer working It now has to be build out of triplex and even though thats good for this stage it makes updating a bit harder since neither of us has a lasercutter for our own too.

Its nice to see there are other groups working on Delta bots too and i'm anxious to see the results. Hopefully next time i'll be able to show some more shots or even a printed part!
