Re: [CAD_CAM_EDM_DRO] 3D Printing

Yeah, I love RAMPs too... my point was that if you wanted to, you *could*
borrow them from your printer to do something else... in other words, the
controller is not a unitasker, but rather a multi-use tool... granted,
there are some very valid reasons for having a unitasker tool, but for the
average maker/DIYer, multi-use tools are far more preferable...
