Best is to send an e-mail using the support ticket system, not the e-mail. They get around 1500-2000 e-mails a day, so your mail can take weeks to process.

hello, I see a lot of questions about "multiple extruders" on the makerbot and BfB machines, but there are some drawbacks on having multiple extruders (this is currently true for all machines with dual extrusion): [*:3dub05x2]Unwanted extrusion. The bowden tube (that feeds the filament in the printhead) is a bit flexible. When you stop the printhead in the middle of a print, it will continue to extrude a couple of mm, even when you are not printing. For dual printheads, this means that you get a little blob on your print when you are changing printheads. Onliest thing to prevent this is to cool down the printhead so that the plastic will not become liquid. [*:3dub05x2]Switching of printhead. The printhead will need to reheat itself if you are printing in multiple colors, to prevent the problem of dripping. This takes time & will reduce speed. The printhead will also change for every dual color layer. [*:3dub05x2]Software is not adjusted to print in multiple colors. Even with makerbot, you need to have 2 STL files (one for every color), create 2 files, and then merge them together. It is not possible to print "1 file". [*:3dub05x2]Print in 1 color at a time. The printhead cant print multiple colors, at least not at the same time. Its either color 1 or color 2, not a mix of both. So best is just to print 1 color, then change filament, and print the second color. Ultimaker has support for dual extrusion, they had it even before the makerbot came with "dualstrusion", but Ultimaker never made dual extruders due to the problems that I mentioned. What I would recommend for you (and I think this is the best solution) is to make the print in color 1 (and leave a little bit of space for the text), change filament, print the letters in color 2, and glue them on the print with a drop of superglue. The machine is accurate enough to do that (and you wouldnt lose too much time)

They dont work in the weekends...

Is "never heard of it" also an option?

Petition is noted, will ask for it next week at UM headquarters. However, when they are shipping with Marlin, they need to be sure that it is functioning properly

Tutorial of the assembly is on wiki.ultimaker.com. I dont know which one is the latest version, but they rarely differ much between batches. The Ultimaker one should be the latest "official" one. Dont know how thick the wood is, but I think it was 4mm triplex. Electronic board is RAMPS 1.5.4, not makerbot Gen 4. Be careful about that one

Hello. Happy that another ultimaker owner joined the club. How is the printing going, and what was your first print?

I also mentioned this in the ultimaker troubleshooting guide.

But keep in mind couple of things: 1. I cant say when it will be made public. Depends on the UM team. 2. Upgrading will be possible for all UM machines, so if you buy a machine now, you can buy an upgrade kit when it gets out. Its a promise of mine. Else UM gets stuck with a lot of stuff that they cant sell. 3. There is a possibility that it will never make it into the market. Its a prototype, not the next-gen ultimaker. Its same with the UM+, it never made it into the market, because of the next rule. 4. Ultimaker wants to deliver quality, not quantity. If its not to quality standard, it wont get on the market. And before I forget, the UM team has 2-head printers, but they dont comply with rule 4...

Cracked nozzle head? Sounds like something went wrong during shipping, or a production fault that slipped through the checks. Best is if you call/mail ultimaker, send them a picture of the cracked nozzle, and ask for a replacement. They have some spare parts for these cases. There are some topics about heating the nozzle and then screwing it apart, but dont know if that will work (aka I never tried).

Really hard to tell (took me an hour to think about the best way to say it). Its actually more than just adding a dual head. I would classify it as MTV's "Pimp my ride", where they take an old car and convert into a new one. But be sure that I (and the UM team) wont disappoint current owners of the ultimaker. Something I learned from school: "Never create something new if it already exists, but make it faster & better instead. It will save you a lot of time and disappointments later."

I can only say that I am working on a research project for Ultimaker. Hopefully drop some jaws when my research is released. I am sure that its something you have never seen on a 3d-at-home machine EDIT: Daid, you are right. The ultimaker was designed with dual extrusion in mind, but the dripping made it utterly impossible to print good prints. Take also in account that the bowden tube also causes a little bit of extrusion even when the thing is not extruding.

If we knew, then they would be out of business

Makerbot, BfB, everything else at this moment. If they use STL files, they will need one file per printhead. They convert it into 1 g-code file for the printer. But if you design an object with multiple colors, you need to have multiple files (one for every color).

Make them. STL has the limiting factor that it can only process 1 color. I am working on a way to use multiple colors in 1 file, but that can take some time.

That would be very uncommon. In fact, if that happens you would be the first to know

Added the solution for this problem to the wiki.

I came from the BfB rapman... I would say that one was a 1000 bucks down the drain actually. Its sitting here using the space, half-broken because I didnt want to print replacement parts for it. I am afraid that if I transport it somewhere, it would break apart :S If someone knows a good use for it, please tell me. Use the parts to build a 2nd ultimaker. The motors, rods and electronics should be good. You could also use the parts for an eggbot or an CnC mill. Or sell the parts. Actually have an eggbot lying around. Pretty funny stuff, especially when its eastern or when the chickens are laying eggs. I am thinking about building an ultimaker clone (since the stepper motors are bigger). I wish I had some free tinkering time...

Nice one. Are there any files of it online, so we can replicate your beautiful thing? :lol:

I would say its a crooked polulu, if I read this: If I read correctly: You changed the z-motor to another axis and then it works fine? If so, then I would get a replacement "polulu stepper" from Ultimaker.

Well, I am sure that it will come as an upgrade (for older machines) and an extra addition for the newer machines. Should wait and see

That is correct. I am pretty sure that they hired someone to answer the support tickets, but that can take some time. If you happen to have defective hardware, they will send you a replacement free of charge (in some cases the customer bought a replacement locally, and ultimaker paid it back). Also the community is really willing to help if you happen to have problems. I am sure that they are working on a HBP, but it wont be on sale unless they are sure that it meets their quality standards (heating quickly, easy to use, ...)

I tried 240mm/s (800%) with an experimental ultimaker (one from the protolab) and used skeinforge 35 with failsafe settings. Didnt print the nicest prints at all, but it was fast as hell (was literally shocked). At one moment I even slowed it down because I got afraid it would shake everything from the table. Hint for those that try to do the same: Start slow, get a hand on the powerswitch, and slowly speed up. When it goes terribly wrong, you can quickly press the button. If you know that normal 3d printers print at a maximum of 32mm/s, and the ultimaker team got speeds upto 500mm/s with their machine, you know how fast an ultimaker can become.

The ultimaker only has an USB connection and extension pins. At the moment it will only work with a computer running replicatorG (repG) or with the Ultiboard (only SD) will it print objects. USB thumb drives wont work. The SDcard only works when you attach an upgrade like the Ultiboard. (i am noting the ultiboard because i know that the firmware works properly with it.)
