Tbf, that really depends on the market share. In the interwebs, I've read a total of 3 - 5 reports of printers catching fire. Now, if 20% of the 3D printers are Prusas, then the rest are chinese ones, which come all with the same bad components. There is not much surprise here, at least for me.

Despite from that, the groups I know usually go like "Yeah, get a CoreXY printer instead. Moving the printbed constantly in XY direction isn't a good idea."
