Can't connect to/control Rostock Max v2 with MatterControl

[Ligerzero_942]

Hello,
I'm having trouble using MatterControl to calibrate my printer in accordance with the official manual.

When i run MatterControl as a non super-user I cannot connect to my printer for "Unknown Reason." When I try again running as root one of a few things will happen.
-MatterControl will attempt to connect but fail with "Invalid Printer Response." Changing the baudrate from 115200 to 250000, trying and failing to connect dut to "invalid Printer Response" then changing BACK to 115200 and attempting to connect will net a "Status:Connected" while in the printing section of the UI it will still state "Attempting to Connect..." During this state the printer cannot be controlled at all, the machine cannot be homed, commands entered in the terminal get no response, and temperature data is displayed as "0.0" rather than the 22 C on the Rostock's LCD display.

-MatterControl will attempt to connect to the printer but never will.

-MatterControl will crash at somepoint.

Something to note:
At one point I was able to get MatterControl to properly connect to the printer (I don't know how though), from their I was able to verify the endstops were working correctly, home the printer and control the cheapskates from the Control menu, turn the hot end and heated bed on and off and attempt to run a PID autotune. However during the autotune MatterControl crashed and I was not able to complete the test. I was able to verify from the printer's LCD display that the temperature in the hotend did not exceed 220C and was able to safely cool back down. Since that crash I have not been able to successfully connect to the printer and control it.

I have also tried using Octoprint but experienced similar connectivity and control issues. I did not try to control the printer in Octoprint but I was able to get a connection.

I'm using
A newly built rostock max v2
Rambo firmware: Repetier 091 ROSTOCKMAX from the seemecnc download site.
MatterControl 1.2
Ubuntu Linux 14.04

Any help or advice would be appreciated.

bah, disregard. just noticed you're using linux.

I was able to fix the connectivity issues by patching pyserial to better use non-standard baud rates. Now i'm calibrating but the MC crashes are making it difficult. I have copy and pasted the error messages I get below:

Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.

Any help or advice would be appreciated.

Please send that information to the MatterControl guys - they don't hang out here much. You can report the crash on the github repo for MatterControl.

Looks like a Mono issue with .Net applications. Have you tried to update to the newest version?

Linux to me is very much an enthusiast OS. I don't do much with it besides tinker with various flavors and configure a LAMP server for HTML/PHP testing.
