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.

True, but thatâs a power issue, if the power to the printer goes out, the print is going to fail anyway 
just make sure the Pi has a sufficient psu.

yeah thanks, I meant that i would apreciate if some one has a good and simple tutorial for using the raspberry pi⌠
Look for âTomâs guideâ 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 itâs 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 donât know how to fix this.
question: why would you build you own image? there is a ready to go image called âOctoPiâ which has everything pre-installed⌠just download the img and flash it to your driveâŚ
I donât understand what I have to do to get started in the sense:
- connect my laptop tot the USB of UM2
- and thenâŚ

Open Cure,
Go to machine settings.
Change Gcode flavor to (makerbot⌠something)
I donât have Cura available at the moment.
The icon changes to Print from usb.
Then you can print with usb.
Hey Freek,
3DPrinterOS controls Ultimaker 2 over USB! You can try it at cloud.3dprinteros.com
Taavi,
You can print through usb I have found, but it didnât (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 âofficially supportedâ 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 âRepRap Flavorâ G-Code, instead of âUltiGCodeâ. If you are using Cura, you will have to go to:
Machine > Machine settingsâŚ
find âGCode flavorâ in the Machine settings window (itâs on the bottom-left for me)
and set it to âRepRap (Marlin/Sprinter)â
Alternatively, you can use other slicers (I use and rather like Simplify3D, although itâs 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, ideallyâUSB 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 âAUTOâ works just fine for me, but in Simplify3D it always tries to connect via my Bluetooth âportâ 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 itâs 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 Arduinoâs own resources as well as the UM2âs GitHub repository for its firmware might be good places to start: https://github.com/Ultimaker/Ultimaker2Marlin if youâre going to be writing your own software targeting a UM2, youâll probably need to get in there at some point. Thatâs probably about all the help I can personally offer. Definitely check out the Ultimaker forum, too. I would be surprised if someone hadnât tackled and documented a helpful project somewhere out there.
