Someone in a local woodworking group was asking about CNC’s. Someone responded about Shapeoko, but felt the need to clarify that all the hobby CNC’s are not actually CNC’s, but rather “NC” (numerically controlled, but not “computer numerically controlled”). According to him and his instructor at a local technical training institute, the fact that they don’t have any kind of feedback was the differentiator.
This was the first time I’d ever seen the term “NC”, much less that all the hobby machines that are being sold are not actually CNC’s, no matter what the industry calls them. But admittedly, my training comes courtesy of Google and YouTube, so my expertise is rather limited. So I thought I’d post and see if there were any opinions in here.
I thought that one might also argue that since you can hook up limit switches to the MPCNC and LR machines, that could be considered feedback, as it helps the machine know where the tool is. But I’m more curious about the differentiation in general.
