I tried with the raspberry pi… but i got stuck with the correct image to download… and im really bad with coding, or linux…does some one have a good tutorial simple (for simple human beings)?

google OctoPi 
its also referenced on the octoprint homepage. it’s basically a ready to go image for the raspberry pi with octoprint on it.
Hi,
Yes you can, Simplify3D allows you to do this. However I tend not to use this feature very much as it means leaving the computer on for the entire print. Also, if it crashes then the print will fail.

yeah thanks, I meant that i would apreciate if some one has a good and simple tutorial for using the raspberry pi…
Look for ‘Tom’s guide’ on youtube. Nice tutorial about the raspberry pi and connecting it to the um2.
Hi Eytan, I gave Octoprint a try last saturday and wrote an Instructable with my struggles 
Maybe it’s helpful to you

Thanx to you all, I will dive into the pi en octoprint first and check that out
This is possible without 3rd party application.
Just set the settings of the GCode flavor to Makerbot
You just have to set the van in the gcode to activate it.
But i don’t know how to fix this.
question: why would you build you own image? there is a ready to go image called “OctoPi” which has everything pre-installed… just download the img and flash it to your drive…
I don’t understand what I have to do to get started in the sense:
- connect my laptop tot the USB of UM2
- and then…
Hey Freek,
3DPrinterOS controls Ultimaker 2 over USB! You can try it at cloud.3dprinteros.com 3
Taavi,
You can print through usb I have found, but it didn’t (may no longer apply) respect endstop limits
try a wifi SD card, then use prontrface to initiate print from sd card?
I think what you want can be achieve with Astroprint. Let me know
No, you can only upload files using the sd card.
Yes, you certainly can. While print-over-USB for the Ultimaker 2 is currently not “officially supported” by Ultimaker (the company), because some users have experienced mid-print errors caused by slow or faulty USB connections, the Ultimaker 2 (and Cura) can do it.
You will just need to pass the UM2 “RepRap Flavor” G-Code, instead of “UltiGCode”. If you are using Cura, you will have to go to:
Machine > Machine settings…
find “GCode flavor” in the Machine settings window (it’s on the bottom-left for me)
and set it to “RepRap (Marlin/Sprinter)”
Alternatively, you can use other slicers (I use and rather like Simplify3D, although it’s not free) which will enable it more or less automatically.
You may encounter some issues with USB printing, like mid-print stops or glitches that cause your printer to behave weirdly or print incorrectly (although I think most people have no problems with it, myself included). To minimize these issues, use a nice, short USB cord (no more than 6ft, ideally—USB protocols do a lot of error correcting and the longer the cable is the more error correcting that needs to happen) and connect it directly to your computer, instead of through a USB hub.
If you have issues with connecting to the printer, make sure you have the Serial Port and baudrate correct (in Cura “AUTO” works just fine for me, but in Simplify3D it always tries to connect via my Bluetooth “port” by default, so I have to remember to change it to USB).
Hope that helps!
Yes this helps, thnxs, I am going to try this out
What i really want to do is to do it with my own slicer. do you know where i can find the specification of the USB interface what to send.
(I can probably can find this out using simplify and look what simplify is sending, but it’s more easy to start with the documentation)
Hmm, well… the Ultimaker 2 is more-or-less completely Open Source and the hardware is built on top of Arduino. So Arduino’s own resources as well as the UM2’s GitHub repository for its firmware might be good places to start: https://github.com/Ultimaker/Ultimaker2Marlin 3 if you’re going to be writing your own software targeting a UM2, you’ll probably need to get in there at some point. That’s probably about all the help I can personally offer. Definitely check out the Ultimaker forum, too. I would be surprised if someone hadn’t tackled and documented a helpful project somewhere out there.
