@larsbrubaker ahhh that makes sense. Good to know! I'll stick to the windows version then. Thanks again for all your hard work.

@larsbrubaker So I just downloaded the alpha on my Windows machine and it works perfectly! Problem fixed! Thanks!

I also tried it on my two mac machines (one very stable hackintosh and one Macbook Pro 2015) and found that the problem is still there on those. I don't have linux installed at the moment so I can't test it on that.

Would it be possible for you to take a look at the Mac OS version as well?

Thanks in advance!

@larsbrubaker Fantastic! Thanks so much for taking a look at that and I'm glad the support trick worked! I'll download the alpha now to try it and report back. Cheers!

I've had this issue for a while now and its driven me crazy as the USB connection to my Flashforge Creator Pro sometimes seems to freeze mid print - so the SD Card *.x3g route seems to be the most reliable way for me. But I just couldn't seem to get the program too produce the *.x3g files.

However... I THINK I FINALLY FOUND A WORKAROUND!

Not sure if this will work for others (I would be interested to know) but here goes... So I found that Mattercontrol 2.0 only seems to fail to export the *.x3g IF it comes up with the "Possible Unsupported Parts Detected" error in the export file window. So I found if I then made sure to generate supports, it started to export the *.x3g files just fine.

But that was annoying as there were a few times when I DIDN'T want to print with supports. So I found that if I opened the "Generate Support" tab at the top of the main window (next to the "Arrange All Parts" button) and set the "Overhang Angle" to 0, the error went away and I could export unsupported parts.

Like I say, no idea if this will help anyone else, but thought I would share in case it does!
