hardly overengineering.
The 5th gen doesn't have a heated bed, the auto calibration apparently doesn't work, the extruders are crap and I haven't come across anyone who's got the wifi or on board camera to work properly.

I'd have to go for seriously under engineered, badly made and not a patch on the first and second generation models.

Given that the two 3d printers in my workshop are rip offs of older makerbot models - as are many thousands the world over. It's sad to see a company that obviously got it absolutely right early on, to hit such a low ebb.
