Error checking

[ajlunis]

I see in the code that you already have a TODO for this, but I really wish there was file error checking implemented. Around 1/4 of the time with the stock QIDI Print software, even over Ethernet, I get incomplete files and only find out when it tells me "Invalid GCode" hours into the print. I'd be willing to pay a decent amount of money if you're able to implement this or have any insight. Support wasn't very helpful. Thanks.

Ya, haven't got around to it - been learning blender 2.8.. ;). I'll try to get to it in December along with a progress bar.
