Arch linux issue - Cannot access a disposed object

1karcio · April 2016

Hi Guys

Sometimes I hit this issue, but problem is sometimes. Could you please see logs? What more info you need.

Linux xxxx 4.4.5-1-ARCH #1 SMP PREEMPT Thu Mar 10 07:38:19 CET 2016 x86_64 GNU/Linux

SOFT: Repetier-Host V1.6.1

Printer: Fabrikator Mini 3D

output ...

Unhandled Exception:

Issue is really annoing. Could you please give me some advice. Where I should look at? I would add attchment, stl file but I think I can't do that here.

The backtrace shows no line coming from repetier-host, so it must be some background code from .NET. SO maybe reading registry (homedir/.mono/Repetier-Host or so).

Can you say when this message appears to guess what it might belong to?

HI Sorry I forgot to mention. This happens when I do slice,

Like:
1. Open STL project
2. Slice with CuraEngine (Recomended for Fabrikator mini 3d)

This happens randomly but very often on my two machines with Arch linux, I will check this homedir/.mono/Repetier-Host tonight and I will paste what I found.

I'm using official package from http://download.repetier.com/files/host/linux/repetierHostLinux_1_6_1.tgz
I know there is package in AUR but I did not use it yet.

Hi guys

an idea what is wrong. Sometimes when I doing slice with the same parameters all works fine, sometimes not.
