MatterControl 2.0 exits suddenly

  • I'm just getting started with MC 2.0 and the first small print ran fine but the second one exited with no warning or message on a simple file that's printing fine under MC 1.5 right now. My buddy who has been using MC 1.7 said his first experience with MC 2.0 also crashed. Is MatterControl 2.0 really buggy or should I give it another try?

    Hey @Cabacon

    We do not normally get too many reports from our users on 2.0 that it crashes without warning like you are experiencing but we welcome a crash report on our GitHub if one gets generated. I would highly recommend trying to stick to the most recent build of Mattercontrol as any issues you encounter will will try to take care of rather quickly depending on severity.

    From my experience MC 2.0 is not all that buggy, and to be honest, our tech team are going to see the majority of the issues outside of the development team.

    Let me know if you have any questions.

  • Thanks.

    Where would I look to see if a crash report got generated?

    If the computer is able to generate one then it could be exported but if the software just crashes without warning there you may not be able to make one up. We are tracking this same issue on the Mac versions so we may have to get any information we can from you in the GitHub on the computer and computer specification.


  • Hi, i have the same problem with MC 2.0. And i try with MC 1.75 and with this version i have the error: Connection Failed: unknown reason. My printer is a Prusa i3 EG-1(+) on windows 8.1.

  • I have been keeping a log of MatterControl failures on my Mac with OS X 10.11. It is really annoying. I am not familiar with GitHub.

    Exited the program after printing about three layers with no warning or messages.

    Exited the program after slicing a file with no warning or messages.

    Exited the program after slicing a file with no warning or messages.

    Exited the program after printing about 15 minutes with no warning or messages.

  • When "saving as" MC 2.0 will exit without warning or generating an error. It also will not save the file. MC will just close out.
