3D Printing Guinness World Record Try by LeTourneau University

[jebba]

To be honest, I don't quite follow your argument. I quite assure you it is easier to print all of the same thing than a whole variety of things. On the TAZ machines there, which was what made up the large majority of the machines in the video, we printed about 22 different parts. You can see the parts list here:
LulzBot TAZ 3D Printer Parts Printed on a LulzBot TAZ 3D Printer Source Code
We did consider printing all the same thing yesterday, but we didn't want to halt production of actual parts because we figured it didn't matter, and it would interrupt the schedule. We're doing this weekdays during business hours. But if Guiness says it all has to be the same, then we'll just do that--that won't be a problem.
Thanks for your consideration,

I guess I come from an older school of Guinness records where something major needs to be done to get a record, in your case you just ran your day to day operations - which to some might not seem like alot of effort for a record, that's why printing the same thing and actually having some form of rules to the record seems a bit more appropriate for a Guinness record, but I guess for the moment you can sleep at night

Thanks for the Post Jeff. Nice talking to you guys today in New York. I have embedded the video below. Looks you you have pretty much blew away the record attempt of 50, before they even got to try. Should be interesting to see how Guinness handles this:

OMFG, they did 108. We beat them by one. Crazy. We weren't even going to run them all, glad we did!

Actually they set the record at 102. They had 108 in the room, but only 102 of them functioned properly.

How do you guys run all of those printers? I am a developer for botqueue.com, which allows you to control multiple 3d printers, and that would be a lovely stress test after the 0.5 version is released.

It seems like it takes a lot of bandwidth to run all of those bots. How do you guys run them all?

For the older AO-100s, we just had a lot of USB and would have one computer running pronterface drive ~15 or so. For the TAZ, we are putting Beagle Bone Blacks on all of them, and we control them via OctoPrint. We are familiar with Botqueue, but we haven't run it on the cluster. Perhaps we could re-visit that.
Thanks!

Yeah, and with the 0.5 release of BotQueue I'm basically making it easier to handle in house servers as well as make it easier to add bots. Having Lulzbot basically test it with that many bots would be crazy cool. Unfortunately, I wouldn't say that BotQueue in its current version would be very helpful to you as the latest Slic3r version is only 0.9.10b.

We pre-slice all the files then just feed the machines gcode. So they aren't getting new slices on the fly as they are sent to the print job. Each slic3r config gets custom built for that part. Once we get the full 135 TAZ and BeagleBone Blacks on all of them, it may be reasonably "easy" to set up to run botqueue. I have put botqueue on our cluster meeting agenda, so we'll discuss it over the next couple weekly meetings.
Thanks!

Well if there's any features you want while I'm working on the 0.5 version, let me know and I'll get them added.

Thank you!
