GCode export not working and warning message can't be turned back on

[larsbrubaker]

From customer:

• Load GCode file
• Click 'Do not show this again' on warning
• no longer can print gcode file
• make it work
• make it possible to turn warning back on (settings)

I am trying to run GCode from Matter Control that I am slicing on a different computer.

When you first start with Matter Control and load a GCode file and click Print, it will give a warning box saying that you are running a GCode file that may not be for the Printer. It has a 'Do not show this again' checkbox. I clicked the check box after a few times so this wouldn't show up since I am slicing everything with Matter Control and not worried about what it is doing.

Now I do not have the warning box. And when click Print the Matter Control window flashes very quickly and then does nothing else. I can continue on like I had done nothing. It does not start heating the extruder or bed so that tells me it hasn't even starting running the GCode.

I load the file by 'Open' just like I open a STL. It will load up the 2D window just fine, and the settings for the print as expected.

So I guess an easier question would be Can I change the setting somehow to get the checkbox turned back off? I can not find this in the settings anywhere.
