Welcome to the SeeMeCNC Community

Last night I down loaded MatterControl from the SeeMeCNC web site and
successfully printed out two parts. Everything was great. This morning I
decided to try a couple more prints.- the software went bonkers. I uninstalled
the software and reinstalled it. No luck, it did the same thing. When I pick the
Advanced Controls arrow there is a bunch of windows in the lower part that
just keep cycling back and forth. Also there is a window that pops up that says
"Unhandled exception...". See the image below. I really like the software but
if there is not a fix I guess I'm going to have to forget it.

If anyone has any ideas please let me know.

Thanks,

This looks like a backwards compatibility issue. Specifically, I'd say the slice engine selection is invalid in your current version. The SeeMeCNC version of the latest update (1.1) should be available soon, but in the meantime if you download the latest version directly from the MC site I believe it will solve this issue and preserve all current settings.

Originally I did download the software from the MC site. The thing is the bed
was square and when I tried to print, the hot end went down than it went to
the 2 o'clock position. I did some research and found the SeeMeCNC had
a version for the Orion Delta. So I'm a little nervous about downloading
from their site.

I have had some other issues lately (not 3D printing) so I have had to do
couple of "Restore points" on the computer. I don't think that is the problem
but I have to study it little more.

Thanks,

Gotcha. In that case going from the new version back to the old version is almost certainly what caused the issue. The SeeMeCNC pre-release version of 1.1 is available here if you'd prefer to try that.
