Inserting and removal of the SD card maybe an issue. Running from usb is only for testing or small prints IMHO.
Also, the machine does shake at different frequencies depending on different factors. I have mine or a heavy workbench and sometimes a certain infill and speed will setup a harmonic that can knock a WD-40 can over, or at least walk in around awhile.
As far as the heat issue goes the prints are best do in a warm draft free environment. I print in a 40C+ shop and prints are great. Or at least as good as I need because quality is speed dependent to a degree.
Ventalation is an issue. I sat next to my machine (in a big shop but downwind) for 6 hours one day and the fumes totally put me down four hours later with hangover like symptoms for the next few days. A charcoal filter vent system ?? maybe??
