Complaints about the author, methods, prior art etc aside... I've got a lathe here from the late 80's that has CNC. It has tool depth sensing via electrical contact and a bed leveling algorithm. Taking stuff that has existed for 30 years that anyone with community college level machine shop training knows about, tacking "with the 3d printerz!1!!" on and running to the patent office is a giant dick move on the same level as all of the "on the intertubes" patents we've been dealing with.

They may have great intentions. Who knows, but boy-howdy if it walks like a troll...

Same thing with networking, queueing etc. It has existed since the dawn of desktop printers, but now that they add "3D" to the name, it's considered a novel invention? The patent system is flawed.
